Are you sure "I2S" is not to generic? Don't know enough about sound, but
remember this somehow matching against possible alsa ucm profiles.
So this could maybe produce conflicts with such a generic name?

According to the schematics I have, this comes from
vccio_codec
and thus from vcc_io
So please give the regulator node simply a second phandle, like
vcc_io: vccio_codec: REG2 {
and reference the correct regulator here.
See DCDC_REG4 in rk3288-veyron.dtsi for reference.

vccio_codec as well

please use real pin names from schematics fro pinctrl entries when they are
known. This makes greping for things easier.
So please two separate definitions, "hp_det" and "phone_ctl".
