Subject: [PATCH 0/6] drm/panel: atna33xc20: Fix the Samsung ATNA33XC20 panel
Date: Wed, 28 Jul 2021 09:45:51 -0700	[thread overview]
Message-ID: <20210728164557.1882787-1-dianders@chromium.org> (raw)


The overall goal of this series is to make the Samsung ATNA33XC20
panel work more properly. As part of this, we have:
* A bugfix for the recently abstracted DP AUX backlight code.
* A bugfix for the sequencing of the ti-sn65dsi86 bridge driver.
* Removal of the panel from panel-simple and moving it to its own
  driver.

If the bugfixes look good but the rest of the series needs work then
those could land early on their own. There's no real compile time
dependency on the bugfixes, things are just glitchier without them.

NOTE: this series will (slightly) conflict with my other recent series
making eDP panels probable [1]. The conflict is easy to resolve and
I'm happy to repost either once the other lands. It should be noted
that the fact that the Samsung ATNA33XC20 needs its own panel driver
means that it _can't_ handled as a probed driver. I think this is
fine, at least for now. I don't think it would be easy to make a
unified design with this panel and other panels given that it's an
AMOLED panel and has a whole bunch of different components on board.
