[PATCH 0/4] arm64: dts: rockchip: add wolfvision pf5 mainboard

[Michael Riesch]

Habidere,

This series adds the device tree for the WolfVision PF5 mainboard, which
serves as base for recent WolfVision products. It features the Rockchip
RK3568 and can be extended with several different extension boards.

The WolfVision PF5 IO Expander is one example of such an extension board.
The corresponding device tree overlay is also included in this series.

May this be the beginning of a beautiful friendship :-)

Looking forward to your comments!

[PATCH 4/4] arm64: dts: rockchip: add wolfvision pf5 io expander board

[Michael Riesch]

Add device tree overlay for the WolfVision PF5 IO Expander board. This
extension board can be attached to the WolfVision PF5 mainboard and
features
 - TI DP83826 Ethernet PHY

Assuming you keep existing order of entries (whatever it is):

This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


New warnings running 'make CHECK_DTBS=y rockchip/rk3568-wolfvision-pf5.dtb' for 20240325-feature-wolfvision-pf5-v1-0-5725445f792a@wolfvision.net:

arch/arm64/boot/dts/rockchip/rk3568-wolfvision-pf5.dtb: hdmi@fe0a0000: Unevaluated properties are not allowed ('#sound-dai-cells' was unexpected)

just for the record, this is not the fault of the Wolfvision board,
but caused by an undocumented property in the core hdmi node.

I've prepared a fix for the binding in [0], but as Krzysztof noted,
this patch needs a v2 with a change.
