[PATCH v6 0/2] drm/panel: Add panel driver for ChipWealth CH13726A based panels

This driver is based on the one by Teguh Sobirin [0], cut down to only
support the AYN Thor bottom panel.

Due to [1], the AYN vendor description patch has been folded into the
AYN QCS8550 dt series. Which means this series now depends on said
series and it must be picked up before this.
