Subject: drm/radeon/kms: add R4XX mc register access helper.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=905b68223be18937159a29b354e6a332952ff952;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git
drm/radeon/kms: add R4XX mc register access helper.
Atombios will use the mc register access helper and R4XX hw have a
bigger mc range than R3XX so add R4XX specific mc register access
helper.
