Subject: [PATCH 4/6] Revert "drm/panel-simple: Add Samsung ATNA33XC20"
Date: Wed, 28 Jul 2021 09:45:55 -0700	[thread overview]
Message-ID: <20210728094511.4.Id9f076ec5f35633f8ce931051af268a04c45c075@changeid> (raw)
In-Reply-To: <20210728164557.1882787-1-dianders@chromium.org>

This reverts commit 4bfe6c8f7c23b01719671b69fd29b87a35ccd9d6.

This panel's power sequencing really can't be handled properly by
panel-simple because of the special sequencing needed for the EL_ON3
GPIO. The only way it was sorta working in the past was by trying to
jam that signal into the "enable-gpio", but that really wasn't a good
fit. We'll add a custom panel driver for this panel to do it right.
