[PATCH 0/3] drm/msm/dp: Simplify aux code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Here's a few patches that simplify the aux handling code and bubble up
timeouts and nacks to the upper DRM layers. The goal is to get DRM to
know that the other side isn't there or that there's been a timeout,
instead of saying that everything is fine and putting some error message
into the logs.
