 Device-Tree bindings for hdmiphy driver
 
 Required properties:
-- compatible: value should be "samsung,exynos4210-hdmiphy".
-- reg: I2C address of the hdmiphy device.
+- compatible: value should be one among the following
+       1) Samsung,exynos4210-hdmiphy".

+- reg: it holds the physical address infomration for the hdmiphy device.
+       If it is a i2c device, reg holds the I2C address of the phy. For
+       platform bus mapped phy, reg property holds physical address as
