This is used with the ConnectCore 6UL SBC Pro (ccimx6ulsbcpro) board.

Changes in v1 from initial changeset [1]:

* Split configuration change into a different commit
* Provide meaningful commit messages
* Use the new DRM mxsfb driver for the AUO G101EVN010 panel

The "simple-panel" string could be dropped.

It looks good to me.  Ping me when the patch #1 gets accepted and I
will apply the test then.

Two things to keep in mind for next time: please split up DT bindings
and driver changes into two separate patches (checkpatch.pl warns about
this) and keep entries in panel-simple sorted alphabetically.

I fixed the sorting myself and also added a .txt suffix to the DT
binding documentation for consistency with other files in that
directory.

Applied to drm-misc-next, thanks.

Thierry

Re: [PATCH v1 1/4] drm/panel: simple: Add AUO G101EVN010 panel support

[Swapnil Raicha]

Hi Alex,

I am currently working on STM32MP1 based custom board and using the auo,g101evn010 panel.

The panel comes up but the colours are not as expected.
One observation is that when I pull down the notification bar on the Android Screen on the panel, due to the overlay of the notification, the colours in the background seems to be perfect then.

Not getting where to look at for this issue.
Seems to me an issue related to DRM.

Can you please suggest a solution for the same.

Waiting for a reply.

Regards,
Swapnil Raicha.
