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.
Andy Yan (1): imx-drm: imx-hdmi: split imx soc specific code from imx-hdmi
Andy yan (1): move imx-hdmi to bridge/dw-hdmi
