While convenient, it's not a property of the DSI controller (in the SoC). And caused DTB validation issues when a panel was not connected to the board. So add the #address/#size-cells properties to the board dts[i] file where there is a panel and then remove the properties from the SoC dtsi file ... and then from the binding file as well. ad 2) There were a number of issues which were obvious to me how to fix, so I fixed those as well. One of those was the addition of port(s) or endpoints, but for that the context (ie parent nodes) got redefined ... to the same values they had in the SoC dsi node. The SoC dsi node already defined the structure where each port got a label/phandle. That allows for a simplification of the port/endpoint by referencing that label/phandle. My changes were based on yesterday's v6.17-armsoc/dts64 branch: 7f9509791507 ("arm64: dts: rockchip: add DTs for Firefly ROC-RK3588S-PC") Then applied the following patches: 86491c2b99e5 ("dt-bindings: pinctrl: rockchip: increase max amount of device functions") 6f446bbe412a ("dt-bindings: gpu: mali-utgard: Add Rockchip RK3528 compatible") ab9be0b75af5 ("dt-bindings: display: himax-hx8394: Add Huiling hl055fhav028c") 8358102806c6 ("dt-bindings: power: rockchip: Add support for RK3528") 233eda069994 ("dt-bindings: rockchip: pmu: Add compatible for RK3528") And then validated it with W=1 using dtschema-2025.6.1. The validation log file sizes: - base: 99.8 KiB - dsi: 82.1 KiB - low-hanging-fruit: 68.9 KiB I then checked whether dmesg wouldn't indicate problem on these boards: - Rock64 (rk3328) - RockPro64 (rk3399) - PineTab2 (rk3566) And I didn't find any. I don't have any px30 or rk3399-gru-* based boards, so I couldn't test with those. Changelog: - Move refactoring of port/endpoint definition to its own patch (Quentin) - Move re-ordering of nodes to its own patch (Quentin) Link to v1: https://lore.kernel.org/linux-rockchip/20250627152645.740981-1-didi.debian@cknow.org/ I also identified some other items which could reduce the DTB validation 'noise' substantially: "failed to match any schema with compatible" errors: - 'mps,mp8859': regulator/mp8859.txt - 'realtek,rt5651': sound/rt5651.txt - 'rockchip,rk3368-mailbox': mailbox/rockchip-mailbox.txt - 'rockchip,rk3399-gru-sound': sound/rockchip,rk3399-gru-sound.txt - 'ti,tsc2007': input/touchscreen/tsc2007.txt Other issues where a (small?) fix may help a lot: px30: - /isp@ff4a0000/ports: graph node has single child node 'port@0', #address-cells/#size-cells are not necessary - /syscon@ff140000/lvds/ports/port@0: graph node has single child node 'endpoint@0', #address-cells/#size-cells are not necessary - /dsi@ff450000/ports/port@0: graph node has single child node 'endpoint@0', #address-cells/#size-cells are not necessary rk3399: - /usb@fe800000: node has a unit name, but no reg or ranges property - /usb@fe900000: node has a unit name, but no reg or ranges property Cheers, Diederik Diederik de Haas (10): arm64: dts: rockchip: Move dsi address+size-cells from SoC to px30 boards arm64: dts: rockchip: Move dsi address+size-cells from SoC to rk3399 boards dt-bindings: display: rockchip,dw-mipi-dsi: Drop address/size cells arm64: dts: rockchip: Simplify VOP port definition on rk3328 arm64: dts: rockchip: Simplify edp endpoints on several rk3399 boards arm64: dts: rockchip: Simplify mipi_out endpoint on rk3399 RP64 dtso arm64: dts: rockchip: Move mipi_out node on rk3399 haikou demo dtso arm64: dts: rockchip: Fix LCD panel port on rk3566-pinetab2 arm64: dts: rockchip: Drop unneeded address+size-cells on px30 arm64: dts: rockchip: Drop regulator-compatible property on rk3399 .../rockchip/rockchip,dw-mipi-dsi.yaml | 6 ----- .../rockchip/px30-cobra-ltk050h3146w-a2.dts | 2 ++ .../dts/rockchip/px30-cobra-ltk050h3146w.dts | 2 ++ .../dts/rockchip/px30-cobra-ltk050h3148w.dts | 2 ++ .../dts/rockchip/px30-cobra-ltk500hd1829.dts | 2 ++ arch/arm64/boot/dts/rockchip/px30-evb.dts | 2 ++ .../rockchip/px30-pp1516-ltk050h3146w-a2.dts | 2 ++ .../dts/rockchip/px30-pp1516-ltk050h3148w.dts | 2 ++ arch/arm64/boot/dts/rockchip/px30.dtsi | 6 ----- .../dts/rockchip/rk3326-anbernic-rg351m.dtsi | 2 ++ .../dts/rockchip/rk3326-gameforce-chi.dts | 2 ++ .../boot/dts/rockchip/rk3326-odroid-go.dtsi | 2 ++ arch/arm64/boot/dts/rockchip/rk3328.dtsi | 6 +---- arch/arm64/boot/dts/rockchip/rk3399-base.dtsi | 4 ---- .../dts/rockchip/rk3399-gru-chromebook.dtsi | 15 ++++--------- .../boot/dts/rockchip/rk3399-gru-scarlet.dtsi | 4 +++- .../boot/dts/rockchip/rk3399-hugsun-x99.dts | 2 -- .../boot/dts/rockchip/rk3399-pinebook-pro.dts | 15 ++++--------- .../dts/rockchip/rk3399-pinephone-pro.dts | 2 ++ .../rk3399-puma-haikou-video-demo.dtso | 12 +++++----- .../boot/dts/rockchip/rk3399-rock-4c-plus.dts | 2 -- .../dts/rockchip/rk3399-rockpro64-screen.dtso | 22 ++++++------------- .../rockchip/rk3399-sapphire-excavator.dts | 16 ++++---------- .../boot/dts/rockchip/rk3566-pinetab2.dtsi | 6 ++--- 24 files changed, 54 insertions(+), 84 deletions(-) -- 2.50.0
