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 differences, 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 make this patch set:
(1): fix some CodingStyle warning to make checkpatch happy
(2): split out imx-soc code from imx-hdmi to dw_hdmi-imx.c
(3): move imx-hdmi to bridge/dw-hdmi, and convert it to a drm_bridge driver
(4): add rockchip rk3288 platform specific code dw_hdmi-rockchip.c
Changes in v8:
- correct some spelling mistake
- modify ddc-i2c-bus and interrupt description
- Add documentation for rockchip dw hdmi
- add support for rockchip rk3288 hdmi
Changes in v7:
- remove unused variables from structure dw_hdmi
- remove a wrong modification
- add copyrights for dw_hdmi-imx.c
Changes in v6:
- rearrange the patch order
- move some modification to patch#6
- refactor register access without reg_shift
- move some modification from patch#5
Changes in v5:
- refactor reg-io-width
Changes in v4:
- fix checkpatch CHECK
- defer probe ddc i2c adapter
Changes in v3:
- split multi register access to one indepent patch
Changes in v2:
- use git format -M to generate these patch
