Subject: [PATCH 0/1] drm/panel: st7703: Fix initialization failures on Xingbangda XBD599

This patch fixes intermittent panel initialization failures and screen
corruption during resume from sleep on panel xingbangda,xbd599 (e.g.
used in PinePhone).

It was originally submitted by Ondrej Jirman in July 2020:
https://lore.kernel.org/all/20200716123753.3552425-1-megous@megous.com/

The original patchset contained two patches. One of them broke the panel
on the Purism Librem 5.

This is the concluding message from Guido Günther in that thread:
https://lore.kernel.org/all/20200801110409.GA6351@bogon.m.sigxcpu.org/#t

Guido wanted changes to the commit message. I updated it to adress his
requests.

I send this patch in Ondřej's name with his consent.

The patch is based on drm-next.

Please let me know what you think.

Thanks,
  Frank
