nit: remove extra empty line.

"tbs" isn't documented in
"Documentation/devicetree/bindings/vendor-prefixes.txt". You need to add
a line for it.
Also, board compatible should only be "tbs,tbs2910".

You already include gpio.h, use GPIO_ACTIVE_{HIGH,LOW} for all gpios
properties.

I'd say default-state = "keep". Also give the LED a more meaningful
name like "power" and add a label = "power:blue".
And: There is whitespaces instead of TABs in the last level of
indentation.
Besides the comments above, this looks good to me from a DT
point-of-view, so you can add my

and don't forget to add Shawn and Sascha when sending a v2.
