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 be accessed by word), 4K support(imx6 doesn't support 4k, but rk3288 does), and HDMI2.0 support.
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 v10: - split generic dw_hdmi.c improvements from patch#11(add rk3288 support) - add more display mode support mpll configuration for rk3288
Changes in v9: - move some phy configuration to platform driver
Changes in v8: - correct some spelling mistake - modify ddc-i2c-bus and interrupt description - Add documentation for rockchip dw 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
