To put 'pinctrl-name' and then 'pinctrl-0' is better? :-)

The i2s dt node can drop "pinctrl-0/pinctrl-name" properties.

I will re-send this patchset (v2) after fixing it.

Shouldn't the label be rather called "i2s2" as the pinctrl entry below
suggests?

"pinctrl-name" is not a valid property. I suppose it should be
"pinctrl-names".
