[PATCH v2 0/3] arm64: dts: rockchip: Enable the NPU on some rk3588 boards

[Ricardo Pardini via B4 Relay]

This series enables the NPU on a few Rockchip rk3588 boards.
In every case here, the required regulator was already in place.
As suggested by Jimmy Hon [1], since the NPU power domain supply is
being described, also remove the always-on property from the regulator.

In Jimmy's words: the commit message for the introduction of the 
pd_npu label mentions how the regulator no longer needs to be always on. 
[2]

I might send a separate series dropping always-on from the same regulator
on the boards that have already added the NPU bits with no changes to 
the regulator. I wonder if I should add Fixes for those.
