This series adds support for the display present in the PinePhone Pro. Patch #1 adds a devicetree binding schema for panels based on the Himax HX8394 controller, such as the HSD060BHW4 720x1440 TFT LCD panel present in the PinePhone Pro. Patch #2 adds the panel driver for this controller and finally patch #3 adds an entry for the driver in MAINTAINERS file. This version doesn't include the DTS changes, since Ondrej mentioned that there are still things to sort out before enabling it. The DTS bits will be proposed as a follow-up patch series. This allows for example the Fedora distro to support the PinePhone Pro with a DTB provided by the firmware. This is a v5 of the patch-set that addresses issues pointed out in v4: https://lists.freedesktop.org/archives/dri-devel/2022-December/384810.html The patches were tested on a PinePhone Pro Explorer Edition using a Fedora 37 Workstation image.
