From aa1fffaa33a6497969d964216c900de071cc12c6 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0478/4131] drm/amd/display: re-order the luma chroma addres
updation
The DCE engine triggers scan as soon as the luma
address is updated, since it is updated before chroma address
the chroma data is not scanned out properly or in order.
This patch fixes this by re-ordering the same.
BUG: SWDEV-119421
TEST: (On Chromium OS for Stoney Only)
* Executed below tests to see YUV(underlay) & RGB planes on eDP
plane_test --format XR24 --size 500x100 -p --format NV12 --size 500x500
* Chroma data is scanned properly.
