[PATCH 0/2] Introducing I915_FORMAT_MOD_4_TILED_XE2_CCS Modifier for Xe2

[Juha-Pekka Heikkila]

These patches modify how Intel Xe driver handle compressed Tile4 framebuffers
on display with Xe2 hardware. Specifically, here is added support for
I915_FORMAT_MOD_4_TILED_XE2_CCS as a valid tiling mode for new framebuffers. 

This change remove unconditional decompression of Tile4 type framebuffers
on Xe2 display, as handling compressed versus not compressed framebuffers
have different requirement on discrete graphics than on integrated.
