From f672a82c76e8690f2b34d25975abce1b00b61877 Mon Sep 17 00:00:00 2001
From: Mauro Rossi <issor.oruam@gmail.com>
Date: Sun, 12 Aug 2018 21:43:02 +0200
Subject: [PATCH 0060/2940] drm/amdgpu: enable ABGR and XBGR formats (v2)
Add support for DRM_FORMAT_{A,X}BGR8888 in amdgpu with amd dc disabled
(v2) Crossbar registers are defined and used to swap red and blue channels,
keeping the existing coding style in each of the dce modules.
After setting crossbar bits in fb_swap, use bitwise OR for big endian
where required in DCE6 and DCE8 which do not rely on REG_SET_FIELD()
