[PATCH V4 0/6] dw-hdmi: make imx hdmi publicly used by dw hdmi compatible platform

[Andy Yan]

We found freescale imx6 and rockchip rk3288 and Ingenic JZ4780 (Xburst/MIPS)
use the interface compatible Designware HDMI IP, but they also have some
lightly difference, such as phy pll configuration, register width(imx hdmi
register is one byte, but rk3288 is 4 bytes width and can only access by word),
4K support(imx6 doesn't support 4k, but rk3288 does).
 
To reuse the imx-hdmi driver, we do this patch set:
patch (1): split out imx-soc code from imx-hdmi to dw_hdmi-imx.c
patch (2): move imx-hdmi to bridge/, and rename to dw-hdmi to
make this driver indepent of drm-imx . 
And we will add rockchip platform specific code dw_hdmi-rockchip.c later,
this is depend on drm-rockchip.

Changes in V4:
- return defer if can't get ddc i2c adapter
- fix checkpatch warns
 
Changes in V3:
- refactor multi byte register access, and split it
  to one indepent patch
- convert it to a drm_bridge driver
 
Changes in V2:
- use git format-patch -M to generate these patch
- remove change-id
- remove from
