Subject: [PATCH 0/2] drm: xlnx: zynqmp_kms: 16 bpp fixes for Xorg startup on AMD KV260

Hi,

Currently on default yocto images Xorg fails to start on AMD KV260
because 24/32 color depth gets detected but does not actually work.

These two patches fix the issue and now 16 bpp gets detected
and Xorg starts and draws on external HDMI display using
kernel.org based linux-yocto kernel.
