Subject: [PATCH 0/5] High color depth support for RK3576/RK3588 HDMI output

Since both Rockchip RK3576 and RK3588 SoCs are capable of handling 10
bpc color depth HDMI output and we've already landed the required HDPTX
PHY driver changes to support the setup, let's add the missing bits and
pieces to VOP2, DW HDMI QP encoder and bridge library.
