Subject: [PATCH v2 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.

Please note this conflicts with the HDMI CEC series [1], hence I added
that as a b4-managed dependency.

Changes in v2:
- Replaced patch 'drm/rockchip: vop2: Add high color depth support' with
  'drm/rockchip: vop2: Check bpc before switching DCLK source'
- Rebased series onto next-20250825 while adding the HDMI CEC series as
  a dependency
- Link to v1: https://lore.kernel.org/r/20250721-rk3588-10bpc-v1-0-e95a4abcf482@collabora.com
