[PATCH v2 0/7] Add DSI support for RK3128

[Alex Bee]

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, add support for an additional clock 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.

Please see individual patches for details about the changes.
