Add Samsung AMS581VF01 panel support

[PATCH 0/2] Add Samsung AMS581VF01 panel support

Posted by Danila Tikhonov 1 month, 2 weeks ago

This patch series adds support for the Samsung AMS581VF01 panel, used in
the Google Pixel 4a (sm7150-google-sunfish). Unlike many other devices,
which may use different panels in various revisions, the Pixel 4a has only
one possible panel option. Also this panel is not used in other devices.
Testing has been done by me.

The driver initializes the panel in normal mode (High Brightness Mode and
Brightness Dimming are disabled). High Brightness Mode and Brightness
Dimming are not supported yet.

In the downstream device tree, the panel is named as
"dsi-panel-sofef01-1080p-cmd".
