Subject: [PATCH v2] arm64: dts: rockchip: add regulator-enable-ramp-delay to RK860-0/-2/-3 regulators
The RK860-0/-1/-2/-3 regulators are used on rk3588 boards in addition to
the main pmic, to supply components like the big cpu-clusters and npu.
So far nobody had a use-case for turning these off. The supplies for the
big cpu-clusters are on by default and those clusters normally are not
completely turned off during runtime.
This changed with the new Rocket driver for the NPU, which does use
runtime-pm and thus does turn off and on the NPU's supply regulator as
needed. This regulator is also needed to run to actually turn on the
power-domain for the NPU.
If the rocket driver now runtime-suspends while running a load and then
runtime-resumes again, hangs can be observed with messages like
rockchip-pm-domain fd8d8000.power-management:power-controller: failed to set domain 'nputop' on, val=0
A way to "fix" that issue when it happens, is to set the regulator to
always-on. This suggests that the power-domain is trying to get power
from the regulator before it is ready to deliver power.
And in fact the datasheet for the regulator defines an "Internal soft-start
time" characteristic. For a target output voltage of 1.0V the _typical_
time to reach at least 92% of the output, is given as 260uS.
That means the time 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.
This adds the property to all rk8600, rk8602 and rk8603 occurences that
are in mainline as of 6.16-rc1. There is currently no rk8601 used in
any in-kernel devicetree.

changes in v2:
- also adapt rk8600 in rk3566-radxa-zero-3 (Quentin)
- reword commit description to be easier to understand (Quentin)
