Subject: [PATCH v2 0/1] drm/panel: st7703: Fix resume of XBD599 panel

This is V2 of a patch that fixes flickering after resume from sleep on
panel xingbangda,xbd599 (e.g. used in PinePhone).

Please see here for the discussion around V1:
https://lore.kernel.org/all/20230212120830.46880-1-frank@oltmanns.dev/T/

V1 introduced panel specific functions for the JH057N and XBD599 panels.
Ondřej Dirman deemed this unneccesary and finally convinced me.

Therefore, V2 is a much simpler patch.

The patch is just a refactoring of Ondřej's original patch, that is
already used today by PinePhone distributions like PostmarketOS.

This patch has not been tested with the JH057N panel used in the Librem
5 devkit. I hereby kindly ask for Librem (i.e. Guido) to test this.

The patch is based on drm-next.

Ondřej, since this is just a very minor refactoring of your work, I
would gladly put you as the author, if you wish so.

Thanks,
  Frank
