Subject: [PATCH v4 00/12] phy: rockchip: samsung-hdptx: Support high color
 depth management

This series relies on the new HDMI PHY configuration options [1] (patch
included here for convenience) to provide high color depth management
for rockchip-samsung-hdptx, and to introduce a proper solution to setup
the TMDS character rate on this PHY.
