Subject: [PATCH 01/28] omap3: beaglexm: fix EHCI power up GPIO dir
|
|
|
|
EHCI enable power pin is inverted (active high) in comparison
|
|
to vanilla beagle which is active low. Handle this case conditionally.
|
|
|
|
Without this fix, Beagle XM 4 port EHCI will not function and no
|
|
networking will be available
|
|
|
|
[nm@ti.com: split up, added descriptive changelogs]
