Message

Hello,

The following patches:
- Add support for configuring the width-mm and height-mm DRM mode
  properties in the SimpleDRM driver via Device Tree
- Document these two new Device Tree properties

This is useful for allowing interfaces such as Phosh to calculate       
proper scaling values.

Changes since RFC:
- Switch to using 32-bit DT property
- Report errors for return values of of_property_read_u32 except -EINVAL
- Calculate default value during probe
- Add documentation
