This series add support for the display present in the PinePhone Pro.

Patch #1 adds a driver for panels using the Himax HX8394 panel controller,
such as the HSD060BHW4 720x1440 TFT LCD panel present in the PinePhone Pro.

Patch #2 adds a devicetree binding schema for this driver and patch #3 adds
an entry for the driver in the MAINTAINERS file.

Finally patch #4 adds the needed devicetree nodes in the PinePhone Pro DTS,
to enable both the display and the touchscreen. This makes the upstream DTS
much more usable and will allow for example to enable support for the phone
in the Fedora distribution.

I only added myself as the maintainer for the driver because I don't know
if Kamil and Ondrej that worked in the driver would be interested. Please
let me know folks if you are, and I can add you too in the next revision.

The patches were tested on a PinePhone Pro Explorer Edition using a Fedora
37 Workstation image.

Best regards,
Javier
