Dear Sir/Madam:

I am having an issue with intel Baytrail GPU DRM driver.

Linux kernel version 3.10.61:
Afer calling function
properties = drmModeObjectGetProperties(drmfd, plane_id, DRM_MODE_OBJECT_PLANE);
 it only returns only one property:
  property->name = "rotation", property->prop_id =4

It looks like that the Baytrail gpu drm driver does not support colorkey.

>From what kernel version , the Baytrail GPU DRM driver starts support colorkey, and is there a way to backport it to kernel 3.10.61?
