Subject: [PATCH 752/752] video/da8xx-fb fix defect with vsync callback
|
|
invocation
|
|
|
|
Fix defect where SGX is running at half of the expected framerate.
|
|
The original patch (@ commit ID 9a1a810516ae9cb3259b898b6879901c5b44fa90)
|
|
seems to have a mistake where it only calls the callback
|
|
for the even or the odd frames depending on the revision of the LCD controller
|
|
This patch corrects this and invokes the callback for both odd and even frame
|
|
for just the Rev02 version of the LCDC (won't find an SGX GPU on a Rev01).
