Changes in v2:
- add tbs vendor prefix to vendor-prefixes.txt
- use GPIO_ACTIVE_{HIGH,LOW}
- add led label and default-state="keep"
- whitespace cleanup
Changes in v3:
- split vendor prefix addition into separate patch
- dual-licensed: GPL or X11
- move iomuxc node to the bottom to improve readability
- remove snvs_poweroff node, not in mainline yet
- whitespace cleanup, hope I got it right now
Changes in v4:
- remove 'regulator-always-on' properties
- remove pinctrl hog_grp and add pins to associated peripheral nodes
- configure pad control settings for all used pins
