v3:
- update license of dts files
- fix node name of switch
- use generic node names
- dropped leading zero in unit-addr of i2c devs

v2:
- updated switch to latest dsa bindings
- update to GPL/X11 dual license
- use stdout-path instead of bootargs
- sort devices under i2c by address
- fix node/label name on touchscreen node
- removed unnecessary status okay for pps node
- removed unnecessary container node in iomuxc
- replaced deprecated fsl,uart-has-rtscts with uart-has-rtscts
