Now as I think of it, patch subject should be rather something like:

ARM: dts: Exynos5420: Add device nodes for GScaler blocks

because the patch alone does not have anything to do with adding device
tree support to GScaler driver.

Also please see remaining comments inline.

coding style: There should be just one space after the label.

coding style 2: Please name the node simply video-scaler. Node name is not
supposed to tell what exactly the device is. The name should be mostly
used for readability, so a person reading the sources can find that this
node represents some video scaler and then by looking at compatible value
he would be able to state that it is an GScaler block compatible with this
on Exynos 5 SoCs.

Best regards,
Tomasz
