The psp tree added a patch to limit the beaglebone to 500MHz when powered by USB, which triggered conflicts in the patches. The 3.2.16 series has been rediffed as well, no functional changes. Signed-off-by: Koen Kooi <koen@dominion.thruhere.net> Signed-off-by: Denys Dmytriyenko <denys@ti.com>

Subject: [PATCH 66/68] drm/radeon: disable MSI on RV515
|
|
|
|
commit 16a5e32b83fd946312b9b13590c75d20c95c5202 upstream.
|
|
|
|
My rv515 card is very flaky with msi enabled. Every so often it loses a rearm
|
|
and never comes back, manually banging the rearm brings it back.
