+Required properities:
+- compatible: platform specific such as:
+ * "fsl,imx6q-hdmi"
+ * "fsl,imx6dl-hdmi"
+ * "rockchip,rk3288-dw-hdmi"
I think we should add a common compatible value "snps,dw-hdmi-tx" here:
compatible = "fsl,imx6q-hdmi", "snps,dw-hdmi-tx";
+- reg: Physical base address and length of the controller's registers.
+- ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
Better make ddc-i2c-bus optional, see the other thread about the ddc i2c
master.
I have the same idea too, but the patch about ddc i2c master has not
landed yet, can we change the ddc-i2c-bus to optional after the ddc
i2c master
patch land?
Check out Documentation/devicetree/bindings/drm/imx/hdmi.txt, it was
already marked as optional. We can't make it required now.
regards
Philipp
OK, got it, thanks
