Hi Daniel,
Some comments. Have a look if it's useful or that you disagree with.
New nodes should be verifiable if possible.
Especially with so many properties.
Could you convert rockchip-dfi.txt and rk3399_dmc.txt to yaml instead of
changing old txt documents?
Add rockchip-dfi.yaml and rk3399_dmc.yaml before this patch in version 6.
Nodes and properties have a sort order. Please fix.
Some goes for [RESEND PATCH v5 3/4].
(This is a generic dtsi. How about cooling and dmc ??)
----
Heiko rules:
compatible
reg
interrupts
[alphabetical]
status [if needed]
----
My incomplete list:
For nodes:
If exists on top: model, compatible and chosen.
Sort things without reg alphabetical first,
then sort the rest by reg address.
Inside nodes:
If exists on top: compatible, reg and interrupts.
In alphabetical order the required properties.
Then in alphabetical order the other properties.
And as last things that start with '#' in alphabetical order.
Add status below all other properties for soc internal components with
any board-specifics.
Keep an empty line between properties and nodes.
Exceptions:
Sort pinctrl-0 above pinctrl-names, so it stays in line with clock-names
and dma-names.
Sort simple-audio-card,name above other simple-audio-card properties.
Sort regulator-name above other regulator properties.
Sort regulator-min-microvolt above regulator-max-microvolt.
