Subject[PATCH V3 0/4] dw-hdmi: make imx hdmi publicly used by dw hdmi compatible platform
Date
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
patch (3): add multi byte register access support
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 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
