Add mt8188 smi supporting in the bindings. In mt8188, there are two smi-common HW, one is for vdo(video output), the other is for vpp(video processing pipe). They connect with different smi-larbs, then some setting(bus_sel) is different. Differentiate them with the compatible string. Something like this: IOMMU(VDO) IOMMU(VPP) | | SMI_COMMON_VDO SMI_COMMON_VPP ---------------- ---------------- | | ... | | ... larb0 larb2 ... larb1 larb3 ...

2022-08-16dt-bindings: memory: mediatek,smi: Update condition for mt8195 smi nodeTinghan Shen1-1/+10
The max clock items for the dts node with compatible 'mediatek,mt8195-smi-sub-common' should be 3. However, the dtbs_check of such node will get following message, arch/arm64/boot/dts/mediatek/mt8195-evb.dtb: smi@14010000: clock-names: ['apb', 'smi', 'gals0'] is too long From schema: Documentation/devicetree/bindings/memory-controllers/mediatek,smi-common.yaml It's because the 'mediatek,mt8195-smi-sub-common' compatible incorrectly matches the 'else' conditions for gen2 HW without gals. Rewrite the 'else' condition to specifically identify the compatibles that utilizing gen2 HW without gals.

The property "clock" should be rename to "clocks", and delete the "items", the minItems/maxItems should not be put under "items".

2021-09-22dt-bindings: memory: mediatek: Add mt8195 smi sub commonYong Wu1-0/+28
Add the binding for smi-sub-common. The SMI block diagram like this: IOMMU | | smi-common ------------------ | .... | larb0 larb7 <-max is 8 The smi-common connects with smi-larb and IOMMU. The maximum larbs number that connects with a smi-common is 8. If the engines number is over 8, sometimes we use a smi-sub-common which is nearly same with smi-common. It supports up to 8 input and 1 output(smi-common has 2 output) Something like: IOMMU | | smi-common --------------------- | | ... larb0 sub-common ... <-max is 8 ----------- | | ... <-max is 8 too. larb2 larb5 We don't need extra SW setting for smi-sub-common, only the sub-common has special clocks need to enable when the engines access dram. If it is sub-common, it should have a "mediatek,smi" phandle to point to its smi-common. meanwhile the sub-common only has one gals clock.

2021-06-21dt-bindings: Drop redundant minItems/maxItemsRob Herring1-4/+2
If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.
