Subject: [PATCH 0/3] drm/msm/dp: Simplify aux code
Date: Fri,  7 May 2021 14:25:02 -0700	[thread overview]
Message-ID: <20210507212505.1224111-1-swboyd@chromium.org> (raw)

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.
