Nice work. This patch should move the binding from Documentation/devicetree/bindings/staging/imx-drm/hdmi.txt to the location instead of making a new file and leaving the old one in place. And use git format-patch -M to highlight any changes. Regards ZubairLK
I add these bindings for dw-hdmi core, because properities like reg, interrupts, ddc-i2c-bus, reg-io-width are used by dw-hdmi core, but properities like compatible, gpr,clk, are platform specific , they are handled by the platform code like dw_hdmi-imx.c and described in platform specific dt binds like /imx-drm/hdmi.txt
