[PATCH v2 0/6] drm/panel: mantix and st7703 fixes and additions

[Guido Günther]

This adds new panel type to the mantix driver as found on the Librem 5 and
fixes a glitch in the init sequence (affecting both panels). The fix is at the
start of the series to make backporting simpler.
It also adds a patch to make st7703 use dev_err_probe().

[PATCH v2 2/6] drm/panel: mantix: Tweak init sequence

[Guido Günther]

We've seen some (non permanent) burn in and bad white balance
on some of the panels. Adding this bit from a vendor supplied
sequence fixes it.

The whole v2 looks fine to me, I'd give the devicetree
maintainers some slack to review the DT patches then I can
apply the whole series unless you have commit access yourself,
just tell me.

Nice.

I hope someone comes around and update all panel drivers to use
dev_err_probe. It is simpler and better than the current code.
And it will fix a lot of drivers that are noisy during deferral.
