Subject: dt-bindings: display: vop2: Add missing rockchip,grf property for rk3566/8
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=47d31e6598e4fda1433e747ef031cb972c57c5ae;p=linux-2.6-microblaze.git

dt-bindings: display: vop2: Add missing rockchip,grf property for rk3566/8

The clock polarity of RGB signal output is controlled by GRF, this
property is already being used in the current device tree, but
forgot to describe it as a required property in the binding file.
