If I understand your intent correctly, I think there's a logic bug in this
patch.

+       if (plane_state->fb->depth > bpp)
+               bpp = 8*3;

Shouldn't that say:

+       if (plane_state->fb->depth < bpp)
+               bpp = 8*3;

That is if the FB bit depth is less than the supported bpp of the display
(36-bit in my case), then clamp the bpp to that of the frame buffer (24-bit).
