I tested this on snow, using:

# turn on backlight
i2c dev 4; i2c mw 48 f 1; i2c mw 48 15 1; i2c md 48 0 20
gpio set gpx30
gpio set gpb20

This seems to work fine.

I also tested that the cros_ec keyboard works, using interrupt 182
instead of 174) in the FDT:

ec-interrupt = <&gpio 182 1>;

So it all looks good to me, thank you.
