> Changes for v2:
> 
> - Rename enet_ext and audio_ext oscillator names
> - Move regulators from simple-bus (and rename to reg_3p3v:

> - Add stdout-path property to chosen node
> - Move iomuxc node to the end (as it is so large)
> - Sort with alphabetical order
> - Rename the default pinctrl to "hog"
> - Move LED pins definition from "hog" to "led" group
> - Add more descriptive names to default pins pinmux definition
> - Use spi-slave property to describe node working in this mode
> - Rename the spidev3 node to slave
> - Introduce new compatible name (lwn,bk4) for spidev driver (to avoid
