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

Some mtk spi nor has dedicated dma(s) inside. Add a new clock name, axi,
for spi nor dma bus clock.

The mt8195 pinctrl driver requires a 'pins' subnode to wrap pin properties.

This will cause any existing DTs that don't have both spi and sf clocks
defined to fail to validate which doesn't seem great.  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).

With an if/then schema adding maxItems/minItems constraints (e.g. 
'maxItems: 2' for existing compatibles). There are many examples in the 
tree.

Why?

Can we constrain this a bit more.

Don't use '_' in node names.

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: ...".

It's because the dtbs_check reports following errors,

/proj/mtk15399/cros/src/third_party/kernel/v5.10/arch/arm64/boot/dts/me
diatek/mt8195-evb.dt.yaml: pinctrl@10005000: i2c0-pins: 'pinmux' is a
required property
        From schema:
/proj/mtk15399/cros/src/third_party/kernel/v5.10/Documentation/devicetr
ee/bindings/pinctrl/pinctrl-mt8195.yaml
/proj/mtk15399/cros/src/third_party/kernel/v5.10/arch/arm64/boot/dts/me
diatek/mt8195-evb.dt.yaml: pinctrl@10005000: i2c0-pins: 'pins_bus' does
not match any of the regexes: 'pinctrl-[0-9]+'
        From schema:
/proj/mtk15399/cros/src/third_party/kernel/v5.10/Documentation/devicetr
ee/bindings/pinctrl/pinctrl-mt8195.yaml

So, I've to add 'pins' to fix this failure.

After discussed with colleagues working on pinctrl, 
'^pins' is fine for them. is this acceptable?
