Subject: [PATCH v3 0/7] Add DSI support for RK3128

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.

changes in v3:
 Dropped the changes for the additional AHB clock for the DSI controller,
 as it's not part of the IP block. (Heiko)

Please see individual patches for details about the changes.
