 TI DS90Ux9xx pinmux

Hi Vladimir,

thanks for your patch!

Can we change the subject to something like "add DT bindings" rather than
"add description" as it is more specific and makes it easier for me as
maintainer.

Please reference the generic binding you're using here:
Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt

Apart from these small nitpicks it looks very standard and good.
