Thanks for using the new meta-schema format and with the correct
license.


The example fails dt_binding_check - I had to do the following to make
it pass:

diff --git a/Documentation/devicetree/bindings/display/panel/feixin,k101-im2ba02.yaml b/Documentation/devicetree/bindings/display/panel/feixin,k101-im2ba02.yaml

+
+    dsi {
         #address-cells = <1>;
         #size-cells = <0>;
         panel at 0 {

Added include to get definition of GPIO_...
And dropped the "&" as it is not OK in the example here.

And please consider if backlight really is a required property.
