[PATCH] arm64: dts: rockchip: add regulator-enable-ramp-delay to RK860-2/-3 regulators

Wed Jun 4 13:24:25 PDT 2025
The RK860-2/-3 regulators are used on rk3588 boards to supply components
like the big cpu-clusters and npu individually.
Most of these things will be, and in fact most regulator nodes right now are,
always-on - probably nobody has tried completely turning of the big clusters
for example.
This changed with the new NPU driver, which does combined runtime-suspends
with the regulator being tied to the power-domain (it supplies the pd).
If the NPU runtime-suspends while running a load and then starts again
hangs can be observed with messages like
rockchip-pm-domain fd8d8000.power-management:power-controller: failed to set domain 'nputop' on, val=0
Removing the regulator from the domain and instead setting it to always-on
"fixes" the issue, which suggests that the domain is trying to get current
from the regulator before it is ready when it gets turned back on.
And in fact the datasheet for the regulator defines an "Internal soft-start
time". For a target output voltage of 1.0V the _typical_ time to reach at
least 92% of the output is given as 260uS.
So that value is dependent on the target voltage (up to 1.5V for the type)
and also the rest of the board design.
So add a regulator-enable-ramp-delay to all rk860-2/-3 nodes we have in
mainline right now. I've chosen 500uS to be on the safe side, as
260uS is the "typical" value for 1.0V and sadly no max value is given
in the datasheet.
