Subject: [PATCH V5 0/7]dw-hdmi: convert imx hdmi to bridge/dw-hdmi
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 V5:
- refactor reg-io-width process
- add dt-bindings
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
