+description: |
+ Rockchip processors include support for multiple power domains which can be
+ powered up/down by software based on different application scenarios to save power.
+
+ Power domains contained within power-controller node are generic power domain
+ providers documented in Documentation/devicetree/bindings/power/power-domain.yaml.
+
+ IP cores belonging to a power domain should contain a "power-domains"
+ property that is a phandle for the power domain node representing the domain.

-Node of a device using power domains must have a power-domains property,

-power domain to use.
-The index should use macros in:
- "include/dt-bindings/power/px30-power.h" - for px30 type power domain.
- "include/dt-bindings/power/rk3036-power.h" - for rk3036 type power domain.

Hi Elaine,
You've changed the license ones again.
Could someone advise about GPL2.0 and legal stuff here?

Is this the correct position for that?

Normally the original author of a patch should be honored with help of
this command below:
git commit --amend --author="Enric Balletbo i Serra
<[email protected]>"
This places a "From: ...." on top of the commit message.
But this is still a conversion/restyle to YAML.
Meanwhile various other authors in the past have made
contributions/comments to this document as well that was GPL2.0 only at
the time.
(I'm just saying: Claiming to be the only author sounds a bit strange here)

Not sure if 'From:' is save to use here at this position for news readers ??

Currently rk3288.dtsi has some 'extra' properties.
One of the purposes of this document is to filter bogus properties in dt
files.
With "minItems: 1" you have 1 to 'endless' options.
Better restrict with:
maxItems: 1
Given this from rk3288.dtsi:
assigned-clocks = <&cru SCLK_EDP_24M>;
assigned-clock-parents = <&xin24m>;
Introduced with patch:
ARM: dts: rockchip: Assign RK3288 EDP_24M input centrally
Moved from rk3288-veyron.dtsi
Please advise if they still are needed or not.
Adding new minor properties should be added as note in the commit
message for review by Rob, because it isn't an exact conversion of the
original.

My review checks tell me I already reviewed this and IIRC that was
pointed out to you in the last version. Am I supposed to review the
whole thing again or is it unchanged or ???. I have no idea with no
version history.
As there are other issues pointed out, I'm going with 'wait for the next
version'.
