Given that your commit message says this is only required for some SoCs shouldn't the minimum clocks requirement depend on which particular SoC/IP version is being used? Not exactly sure how one specifies that in the YAML format. Please submit patches using subject lines reflecting the style for the subsystem, this makes it easier for people to identify relevant patches. Look at what existing commits in the area you're changing are doing and make sure your subject lines visually resemble what they're doing. There's no need to resubmit to fix this alone.

That was true before this. The default for 'minItems' is the number of entries in 'items' (this is not the default for json-schema, but default for DT bindings as that's the common case). > Given that your > commit message says this is only required for some SoCs shouldn't the > minimum clocks requirement depend on which particular SoC/IP version is > being used? Not exactly sure how one specifies that in the YAML format. With an if/then schema adding maxItems/minItems constraints (e.g. 'maxItems: 2' for existing compatibles). There are many examples in the tree. Rob
Hi Mark, Thanks for the reviews and advice.

I'll update the subject at next version. It'll be "dt-bindings: spi: mtk-spi-nor: ...". regards, TingHan
This series adds basic SoC support for Mediatek's SoC MT8195. --- Changes in v6: - rebase on 5.16-rc1 - add new clock name to spi-nor dt-bindings - add "pins" property in pinctrl dt-bindings - fix fails of dtbs_checks - remove "arm,armv8" not matched in yaml from cpu compatile - fix node name of xhci - remvoe xhci upstreaming wakeup properties - remove xhci unused properties address-cells and size-cells - fix node name of ufs-phy - fix node name of spi-nor - fix node name and sub-nodes of pinctrl - fix mmc compatible Changes in v5: - enable basic nodes in mt8195-evb.dts - remove dedicated clock nodes - add mmc2 node - fix interrupt number of pinctrl node - update clock nodes to apply internal fixes - add dt-bindings for perficfg node v4 thread: https://lore.kernel.org/all/20210922093303.23720-2-seiya.wang@mediatek.com/ v3 thread: https://lore.kernel.org/all/20210601075350.31515-2-seiya.wang@mediatek.com/ v2 thread: https://lore.kernel.org/all/20210319023427.16711-10-seiya.wang@mediatek.com/ v1 thread: https://lore.kernel.org/all/20210316111443.3332-11-seiya.wang@mediatek.com/ --- Tinghan Shen (4): dt-bindings: arm: mediatek: add mt8195 pericfg compatible dt-bindings: spi: add new clock name 'axi' for spi nor dt-bindings: pinctrl: mt8195: add 'pins' wrapping node arm64: dts: Add mediatek SoC mt8195 and evaluation board .../arm/mediatek/mediatek,pericfg.yaml | 1 + .../bindings/pinctrl/pinctrl-mt8195.yaml | 307 ++--- .../bindings/spi/mediatek,spi-mtk-nor.yaml | 6 +- arch/arm64/boot/dts/mediatek/Makefile | 1 + arch/arm64/boot/dts/mediatek/mt8195-evb.dts | 209 ++++ arch/arm64/boot/dts/mediatek/mt8195.dtsi | 1034 +++++++++++++++++ 6 files changed, 1410 insertions(+), 148 deletions(-) create mode 100644 arch/arm64/boot/dts/mediatek/mt8195-evb.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8195.dtsi
