Subject: [PATCH v5 08/20] drm/bridge: ti-sn65dsi86: Move all the chip-related init to the start
Date: Fri, 23 Apr 2021 09:58:54 -0700	[thread overview]
Message-ID: <20210423095743.v5.8.Ide8ba40feb2e43bc98a11edbb08d696d62dcd83e@changeid> (raw)
In-Reply-To: <20210423165906.2504169-1-dianders@chromium.org>

This is just code motion of the probe routine to move all the things
that are for the "whole chip" (instead of the GPIO parts or the
MIPI-to-eDP parts) together at the start of probe. This is in
preparation for breaking the driver into sub-drivers.

Since we're using devm for all of the "whole chip" stuff this is
actually quite easy now.
