Subject: [PATCH 3/5] drm: rockchip: add alpha support for RK3036, RK3066, RK3126 and RK3188
Date: Sat, 18 Jul 2020 22:03:21 +0200	[thread overview]
Message-ID: <20200718200323.3559-4-knaerzche@gmail.com> (raw)
In-Reply-To: <20200718200323.3559-1-knaerzche@gmail.com>

With commit 2aae8ed1f390
("drm/rockchip: Add per-pixel alpha support for the PX30 VOP") alpha
support was introduced for PX30's VOP.
RK3036, RK3066, RK3126 and RK3188 VOPs support alpha blending in the
same manner.
With the exception of RK3066 all of them support pre-multiplied alpha.

This patch adds the respective registers to make this work for those VOPs
as well.
