Why not just rename it to pinctrl_alive and remove the comment? The
same goes for all pinctrl nodes below.

Could above two lines be replaced with some meaningful consts? I see
it's done below.

Here and further: if possible, try to use named constants.

Why 2-cells is needed here? If you make it 1, all below reg properties
can be made 1-cell, which removes not needed 0x0.

Does this SoC have USI blocks? If so, maybe this node should be made a

Sure it doesn't need any clock? I remember having some issues until I

Are you sure all those interrupts are actually needed? Please check
this patch: daeb1c2b50fb ("arm64: dts: exynos: drop incorrectly placed
wakeup interrupts in Exynos850"). If you decide to remove those
interrupts, then bindings doc should be changed too I guess.

Move it up to other cmus, to make nodes under soc ordered alphabetically?
