Nit: Should the label be named 'vreg_gfx' (or 'vreg_vdd_gfx)') for
consistency with rest of the file?

For consistency with the rest of sc8280xp, can you rename this

	vdd_gfx_en: vdd-gfx-en-state {

(i.e. drop the 'state' from the label and shorten 'enable')?

Similar here, this should be

	i2c12_default: i2c12-default-state {

And this newline can be removed.
