Subject: [PATCH] [media] OMAP_VOUT: Fix build break caused by update_mode removal in DSS2
Date: Fri, 5 Aug 2011 12:49:21 +0530
Message-ID: <1312528761-18241-1-git-send-email-archit@ti.com>
X-Mailer: git-send-email 1.7.1
MIME-Version: 1.0
Content-Type: text/plain
The DSS2 driver does not support the configuration of the update_mode of a
panel anymore. Remove the setting of update_mode done in omap_vout_probe().
Ignore configuration of TE since omap_vout driver doesn't support manual update
displays anyway.

The Errata 588369 and 539766 demands that clean all operation be done
as clean each way at a time
This patch also raps the implementation under the CONFIG errata
macro so that for non-errata version silicon it can be disabled

Subject: [PATCH 01/10] OMAP3: beagle: add support for beagleboard xM revision C
OMAP3: beagle: add support for beagleboard xM revision C
The USB enable GPIO has been in beagleboard xM revision C.
The USER button has been moved since beagleboard xM.
Also, board specific initialization has been moved to beagle_config struct
and initialized in omap3_beagle_init_rev. Default values in struct are for xMC.

Subject: [PATCH 05/10] omap3: Add basic support for 720MHz part
This patch adds support for new speed enhanced parts with ARM
and IVA running at 720MHz and 520MHz respectively. These parts
can be probed at run-time by reading PRODID.SKUID[3:0] at
0x4830A20C [1].
This patch specifically does following:
* Detect devices capable of 720MHz.
* Add new OPP
* Ensure that OPP is conditionally enabled.
* Check for presence of IVA before attempting to enable
the corresponding OPP.

2e:40:70:f0:12:06
for the ethernet device on my Panda.
Note that this patch requires the fix patch for CPU ID register
indexes previously posted to linux-omap, otherwise the CPU ID is
misread on Panda by the existing function to do it. This patch
is already on linux-omap.

Subject: [PATCH 09/10] HACK: OMAP2+: BeagleBoard: Fix up random or missing MAC addresses for eth0 and wlan0
This was borrowed from the Panda implementation at http://patches.linaro.org/777/
This patch registers a network device notifier callback to set the mac
addresses for the onboard network assets of the BeagleBoard correctly, despite the
drivers involved have used a random or all-zeros MAC address.
The technique was suggested by Alan Cox on lkml.
It works by device path so it corrects the MAC addresses even if the
drivers are in modules loaded in an order that changes their interface
name from usual (eg, the onboard module might be "wlan1" if there is a
USB wireless stick plugged in and its module is inserted first.)

Subject: [PATCH 2/8] OMAP3+: PM: VP: generalize PRM interrupt helpers
We have multiple interrupt status hidden in the PRM interrupt status
reg. Make this handling generic to allow us to pull out LDO status such
as those for ABB from it using the same data structure and indexing. We
hence rename accordingly.
We also fix a trivial warning as the variable does not need exporting:

Subject: [PATCH 3/8] OMAP3+: PRM: add tranxdone IRQ handlers for ABB
OMAP3 and more recent platforms support a PRM interrupt to the MPU for
Adapative Body-Bias ldo transitions.
Add helpers to the OMAP3 & OMAP4 PRM code to check the status of the
interrupt and also to clear it. These will be called from the ABB code
as part of the greater voltage scaling sequence.

From a0a304bd0a2255bc661933ef23b3a0860fbee69d Mon Sep 17 00:00:00 2001
From: Mike Turquette <mturquette@ti.com>
Date: Wed, 29 Jun 2011 17:25:56 -0700
Subject: [PATCH 4/8] OMAP3+: ABB: Adaptive Body-Bias structures & data
Due to voltage domain trimming and silicon characterstics some silicon
may experience instability when operating at a high voltage. To
compensate for this an Adaptive Body-Bias ldo exists. First featured in
OMAP3630, the purpose of this ldo is to provide a voltage boost to PMOS
backgates when a voltage domain is operating at a high OPP. In this
mode the ldo is said to be in Forward Body-Bias. At OPPs within a
nominal voltage range the ABB ldo is bypassed.
This patch introduces the data structures needed to represent the ABB
ldo's in the voltage layer, and populates the appropriate data for 3630
and OMAP4. Not all voltage domains have an ABB ldo, and OMAP34xx does
not have it at all; in such cases the voltage data will be marked with
OMAP_ABB_NO_LDO.

From 8d85fedcb9866f5041e2c63b54d3eff7fd88cf18 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5/8] OMAP3+: OPP: add ABB data to voltage tables
The operating mode of the Adaptive Body-Bias ldo maps directly to the
voltage of its voltage domain. The two modes supported are bypass and
Forward Body-Bias (FBB).
This patch models this relationship by adding an opp_sel paramter to
struct omap_volt_data and populates this type in the 3630 and 4430
voltage tables.
NOMINAL_OPP causes the ABB ldo to be in bypass at that specific voltage.
FAST_OPP causes the ldo to operate in Forward Body-Bias mode.
Not all voltage domains have an ABB ldo and 3430 doesn't have one at
all. In such cases voltages are marked with OMAP_ABB_NO_LDO.

Subject: [PATCH 6/8] OMAP3+: Voltage: add ABB data to voltage domains
Starting with OMAP36xx, some voltage domains have an ABB ldo meant to
insure stability when that voltage domain is operating at a high OPP.
This patch adds struct omap_abb_instance to struct voltagedomain and
populates the data for those voltage domains that have an ABB ldo on
both 36xx and 44xx silicon.

Subject: [PATCH 7/8] OMAP3+: ABB: initialization & transition functions
The Adaptive Body-Bias ldo can be set to bypass or Forward Body-Bias
after voltage scaling is performed.
This patch implements the Adaptive Body-Bias ldo initialization routine
and the transition sequence which is needed after a vc_bypass or
vp_forceupdate sequence completes.

Subject: [PATCH 8/8] OMAP3+: Voltage: add ABB to voltage scaling
Adaptive Body-Bias ldo state should be transitioned (if necessary) after
a voltage scaling sequence completes via vc_bypass or vp_forceupdate
methods.
This patch initializes the ABB ldo's as a part of the greater voltage
initialization function and adds the ABB transition routine to both the
vc_bypass and vp_forceupdate sequences.

Subject: [PATCH 2/2] OMAP2+: OPP: allow OPP enumeration to continue if device is not present
On platforms such as OMAP3, certain variants may not have IVA, SGX
or some specific component. We currently have a check to aid fixing
wrong population of OPP entries for issues such as typos. This however
causes a conflict with valid requirement where the SoC variant does
not actually have the module present.
So, reduce the severity of the print to a debug statement and skip
registering that specific OPP, but continue down the list.

Subject: [PATCH 01/19] PM: OPP: introduce function to free cpufreq table
cpufreq table allocated by opp_init_cpufreq_table is better
freed by OPP layer itself. This allows future modifications to
the table handling to be transparent to the users.

PM: Prevent direct cpufreq scaling during initialization
It is seen that the OMAP specific cpufreq initialization code tries to
scale the MPU frequency to the highest possible without taking care of
the voltage level. On power on reset the power IC does not provide the
necessary voltage for the highest available MPU frequency (that would
satisfy all Si families). This potentially is an window of opportunity
for things to go wrong.

omap3: introduce cpufreq
OMAP OPP layer functions now have dependencies of CONFIG_CPU_FREQ only.
With this patch, omap opp layer now has its compilation flags
bound to CONFIG_CPU_FREQ. Also its code has been removed from pm34xx.c.
A new file has been created to contain cpu freq code related to
OMAP3: cpufreq34xx.c

omap3: cpufreq: allow default opp table init
For board files which choose to override the defaults, the existing
mechanism will work, for boards that would like to work with defaults,
allow init_common_hw to call init_opp_table to initialize if not
already initialized. this will allow all omap boards which have opp
tables predefined for a silicon to use the same.

omap3: opp: make independent of cpufreq
Make opp3xx data which is registered with the opp layer
dependent purely on CONFIG_PM as opp layer and pm.c users
are CONFIG_PM dependent not cpufreq dependent.
so we rename the data definition to opp3xxx_data.c (inline with what
we have for omap2), also move the build definition to be under
the existing CONFIG_PM build instead of CPUFREQ.

Subject: [PATCH 05/19] OMAP: PM: CPUFREQ: Fix conditional compilation
Fix conditional compilation. A conditional expresiion
should follow "#elif", in this case #elif clause should
check whether CONFIG_ARCH_OMAP3 is defined or not
(ie. defined(CONFIG_ARCH_OMAP3)) rather than checking for
the value of the macro.

Subject: [PATCH 07/19] OMAP: cpufreq: Split OMAP1 and OMAP2PLUS CPUfreq drivers.
This patch is an attempt to cleanup the #ifdeferry in the
omap CPUfreq drivers.
The split betwenn OMAP1 and OMAP2PLUS is logical because
- OMAP1 doesn't support opp layer.
- OMAP1 build is seperate from omap2plus.
Includes minor header/copyright updates reported by Todd Poynor.

Subject: [PATCH 08/19] OMAP2PLUS: cpufreq: Add SMP support to cater OMAP4430
On OMAP SMP configuartion, both processors share the voltage
and clock. So both CPUs needs to be scaled together and hence
needs software co-ordination.

Subject: [PATCH 10/19] OMAP2+: cpufreq: move clk name decision to init
Clk name does'nt need to dynamically detected during clk init.
move them off to driver initialization, if we dont have a clk name,
there is no point in registering the driver anyways. The actual clk
get and put is left at cpu_init and exit functions.

Subject: [PATCH 13/19] OMAP2+: cpufreq: only supports OPP library
OMAP2 is the only family using clk_[init|exit]_cpufreq_table, however,
the cpufreq code does not currently use clk_init_cpufreq_table. As a
result, it is unusuable for OMAP2 and only usable only on platforms
using OPP library.
Remove the unbalanced clk_exit_cpufreq_table(). Any platforms where
OPPs are not availble will fail on init because a freq table will not
be properly initialized.

Subject: [PATCH 15/19] OMAP2+: cpufreq: fix freq_table leak
We use a single frequency table for multiple CPUs. But, with
OMAP4, since we have multiple CPUs, the cpu_init call for CPU1
causes freq_table previously allocated for CPU0 to be overwritten.
In addition, we dont free the table on exit path.
We solve this by maintaining an atomic type counter to ensure
just a single table exists at a given time.

Subject: [PATCH 16/19] OMAP2+: CPUfreq: Remove superfluous check in target() for online CPU's.
Current OMAP2PLUS CPUfreq tagret() functions returns when all
the CPU's are not online. This breaks CPUfreq when secondary CPUs
are offlined on SMP system.
The intention of that check was just avoid CPU frequency change
during the window when CPU becomes online but it's cpufreq_init is
not done yet. Otherwise it can lead to notifiers being sent on
a CPU which is not yet registered to the governor.
But this race conditions is already managed by the CPUfreq
core driver by updating the available cpumask accordingly.
OMAP CPUFReq driver make use same cpumask for the notifiers
so the above problem doesn't exist. In my initial implementation
of the OMAP4 CPUFreq driver, I was using 'for_each_online_cpu()'
for notifiers which lead me to add that check. Later I fixed
the notifies but didn't realise that the check has become
redundant then.
Fix it by removing the superfluous check in target().
Thanks for Nishant Menon <nm@ti.com> for reporting issue
with hot-plug and Kevin Hilman <khilman@ti.com> for his
comment on excessive check in target().

Subject: [PATCH 17/19] OMAP2+: cpufreq: notify even with bad boot frequency
Sometimes, bootloaders starts up with a frequency which is not
in the OPP table. At cpu_init, policy->cur contains the frequency
we pick at boot. It is possible that system might have fixed
it's boot frequency later on as part of power initialization.
After this condition, the first call to omap_target results in the
following:
omap_getspeed(actual device frequency) != policy->cur(frequency that
cpufreq thinks that the system is at), and it is possible that
freqs.old == freqs.new (because the governor requested a scale down).
We exit without triggering the notifiers in the current code, which
does'nt let code which depends on cpufreq_notify_transition to have
accurate information as to what the system frequency is.
Instead, we do a normal transition if policy->cur is wrong, then,
freqs.old will be the actual cpu frequency, freqs.new will be the
actual new cpu frequency and all required notifiers have the accurate
information.

From 5edd966fdcf04f3166c1b7028215e502ba7d5275 Mon Sep 17 00:00:00 2001
From: Tony Lindgren <tony@atomide.com>
Date: Tue, 17 May 2011 03:51:26 -0700
Subject: [PATCH 003/149] omap: Use separate init_irq functions to avoid cpu_is_omap tests early
This allows us to remove cpu_is_omap calls from init_irq functions.
There should not be any need for cpu_is_omap calls as at this point.
During the timer init we only care about SoC generation, and not about
subrevisions.
The main reason for the patch is that we want to initialize only
minimal omap specific code from the init_early call.

From b623b767d19edcc2d08909b044e1ab57956d9d49 Mon Sep 17 00:00:00 2001
From: Tony Lindgren <tony@atomide.com>
Date: Tue, 29 Mar 2011 15:54:48 -0700
Subject: [PATCH 004/149] omap: Set separate timer init functions to avoid cpu_is_omap tests
This is needed for the following patches so we can initialize the
rest of the hardware timers later on.
As with the init_irq calls, there's no need to do cpu_is_omap calls
during the timer init as we only care about the major omap generation.
This means that we can initialize the sys_timer with the .timer
entries alone.
Note that for now we just set stubs for the various sys_timer entries
that will get populated in a later patch. The following patches will
also remove the omap_dm_timer_init calls and change the init for the
rest of the hardware timers to happen with an arch_initcall.

From 99573b33f37eede2d3d36ae71c34f5d72ccdc672 Mon Sep 17 00:00:00 2001
From: Tony Lindgren <tony@atomide.com>
Date: Tue, 29 Mar 2011 15:54:48 -0700
Subject: [PATCH 005/149] omap: Move dmtimer defines to dmtimer.h
These will be needed when dmtimer platform init code gets split
for omap1 and omap2+. These will also be needed for separate
sys_timer init and driver init for the rest of the hardware timers
in the following patches. No functional changes.

Subject: [PATCH 006/149] omap: Make a subset of dmtimer functions into inline functions
This will allow us to share the code between system timer and
dmtimer device driver code without having to initialize all the
dmtimers early. This change will also make the timer_set_next_event
more efficient as the inline functions will optimize the code
better for the timer reprogramming.

Subject: [PATCH 007/149] omap2+: Use dmtimer macros for clockevent
This patch makes timer-gp.c to use only a subset of dmtimer
functions without the need to initialize dmtimer code early.
Also note that now with the inline functions, timer_set_next_event
becomes more efficient in the lines of assembly code.

Subject: [PATCH 008/149] omap2+: Remove gptimer_wakeup for now
This removes the support for setting the wake-up timer for debugging.
Later on we can reserve gptimer1 for PM code only and have similar
functionality.

Subject: [PATCH 009/149] OMAP3+: SR: make notify independent of class
Interrupt notification mechanism of SmartReflex can be used by the
choice of implementation of the class driver. For example, Class 2 and
Class 1.5 of SmartReflex can both use the interrupt notification to
identify the transition of voltage or other events.
Hence, the actual class does not matter for notifier. Let the class
driver's handling decide how it should be used. SmartReflex driver
should provide just the primitives.

Subject: [PATCH 010/149] OMAP3+: SR: disable interrupt by default
We will enable and disable interrupt on a need basis in the class
driver. We need to keep the IRQ disabled by default else the
forceupdate or vcbypass events could trigger events that we don't
need/expect to handle.
This is a preparation for SmartReflex AVS class drivers such as
class 2 and class 1.5 which would need to use interrupts. Existing
SmartReflex AVS class 3 driver does not require to use interrupts
and is not impacted by this change.

Subject: [PATCH 014/149] omap2+: Use dmtimer macros for clocksource
Use dmtimer macros for clocksource. As with the clockevent,
this allows us to initialize the rest of dmtimer code later on.
Note that eventually we will be initializing the timesource
from init_early so sched_clock will work properly for
CONFIG_PRINTK_TIME.

Subject: [PATCH 016/149] omap2+: Rename timer-gp.c into timer.c to combine timer init functions
We can keep everything sys_timer and gptimer.c related code in
timer.c as the code will be very minimal.
Later on we can also remove timer-mpu.c, as it can be called from
omap4_timer_init function.
This allows us to get rid of confusing existing files. We currently
have timer-gp.c, timer-mpu.c, and patches have been posted to add
dmtimer.c. There's no need to have these multiple files, we can
put everything into timer.c.

From a72eaf768c2f553f72e7afc0b1c52661b2913022 Mon Sep 17 00:00:00 2001
From: Grazvydas Ignotas <notasas@gmail.com>
Date: Fri, 3 Jun 2011 19:56:33 +0000
Subject: [PATCH 017/149] omap: cleanup NAND platform data
omap_nand_platform_data fields 'options', 'gpio_irq', 'nand_setup' and
'dma_channel' are never referenced by the NAND driver, yet various
board files are initializing those fields. This is both incorrect and
confusing, so remove them. This allows to get rid of a global
variable in gpmc-nand.c.
This also corrects an issue where some boards are trying to pass NAND
16bit flag through .options, but the driver is using .devsize instead
and ignoring .options.
Finally, .dev_ready is treated as a flag by the driver, so make it bool
instead of a function pointer.

Subject: [PATCH 019/149] omap: mcbsp: Drop SPI mode support
We haven't seen any use for the SPI API in McBSP driver over the years. More
over, Peter Ujfalusi <peter.ujfalusi@ti.com> noticed that SPI mode is not
even supported since OMAP2430 so it's very unlikely that we'll see any use
for it in the future either.

Subject: [PATCH 021/149] omap2+: fix build regression
board-generic.c now contains a reference to omap3_timer, but depends
only on ARCH_OMAP2, not on ARCH_OMAP3, which controls that symbol.
omap2_timer seems to be more appropriate anyway, so use that instead.

Subject: [PATCH 023/149] OMAP4: Move common twl6030 configuration to twl-common
Reduce the amount of duplicated code by moving the common
configuration for TWL6030 (on OMAP4 platform) to the
twl-common file.
Use the omap4_pmic_get_config function from board files to
properly configure the PMIC with the common fields.

From 4a1b31f8aed87737ba84e1e5724ecfbe45732bc8 Mon Sep 17 00:00:00 2001
From: Peter Ujfalusi <peter.ujfalusi@ti.com>
Date: Tue, 7 Jun 2011 10:28:54 +0300
Subject: [PATCH 024/149] OMAP3: Move common twl configuration to twl-common
Reduce the amount of duplicated code by moving the common
configuration for twl4030/5030/tpsxx to the twl-common file.
Use the omap3_pmic_get_config function from board files to
properly configure the PMIC with the common fields.

These McBSP port number enums are used only in two places in the McBSP code
so we may remove then and just use numeric values like rest of the code does.

After commit caf64f2fdc48472995d40656eb1a75524c464447 ("omap: Make a subset
of dmtimer functions into inline functions"),
arch/arm/plat-omap/include/plat/dmtimer.h is missing an include of linux/io.h
- add it.

Subject: [PATCH 029/149] OMAP2+: hwmod: Fix smart-standby + wakeup support
The commit 86009eb326afde34ffdc5648cd344aa86b8d58d4 was adding
the wakeup support for new OMAP4 IPs. This support is incomplete for
busmaster IPs that need as well to use smart-standby with wakeup.
This new standbymode is suported on HSI and USB_HOST_FS for the moment.
Add the new MSTANDBY_SMART_WKUP flag to mark the IPs that support this
capability.
Enable this new mode when applicable in _enable_wakeup, _disable_wakeup,
_enable_sysc and _idle_sysc.
The omap_hwmod_44xx_data.c will have to be updated to add this new flag.

Without that, an IP with busmaster capability will not

The HW reset must be de-assert after the clocks are enabled

De-assert the reset after _enable_clocks and before
_wait_target_ready.
Re-assert it only when the clocks are disabled.

Subject: [PATCH 036/149] OMAP: hwmod: Move pr_debug to improve the readability
Move the pr_debug at the top of the function
to trace the entry even if the first test is failing.
That help understanding that we entered the function
but failed in it.
Move the _enable last part out of the test to reduce
indentation and improve readability.

Subject: [PATCH 044/149] OMAP4: hwmod data: Fix L3 interconnect data order and alignement
Change the position of the ocp_if structure to match the template.
Remove unneeded comma at the end of address space flag field.
Remove USER_SDMA since this ocp link is only from the l3_main_1
path that is accessible only from the MPU in that case and not
the SDMA.
