This series aims to add support for the DesignWare MIPI DSI controller and the Innoslicon D-PHY found in RK3128 SoCs. The code additions are rather tiny: It only need some code in the Rockchip dw-mipi-dsi glue layer for this SoC and do some changes in the SoC's clock driver. Support for the phy was already added when the Innosilicon D-PHY driver was initially submitted. I tested it with a 800x1280 DSI panel where all 4 lanes that are supported are used.
changes in v2: To improve power-efficiency when the DSI controller is not in use, I dropped the patch which made hclk_vio_h2p a critical clock and instead added support for an AHB clock to the DSI controller driver and updated the bindings and the addition to the SoC DT accordingly.
