[v6,0/3] arm64: dts: add i.MX95 and EVK board

Message

Add a minimal i.MX95 dtsi and EVK board dts.
i.MX95 has a M33 running SCMI firmware that supports
pinctrl/power/perf/clock and etc.

imx95-pinfunc.h will trigger checkpatch error, that is expected and same
as other i.MX platforms.

In v6, I added back a dependency on pinctrl, because [1] has got A-b/R-b
from Maintainers, so it would be soon got merged.

There will be dtbs_check error before [1] got landed. With [1] merged,
there will be no dtbs_check error.

This patchset is just a minimal support for i.MX95. After this patchset
is accepted, a following patchset will include more nodes and features.

Changes in v6:
- Add pinctrl nodes and pin settings
- Add imx95-pinfunc.h
- Drop fsl,cd-gpio-disable-wakeup which is downstream property
- Per i.MX M33 SCMI firmware, drop unused PERF entries in imx95-power.h
- Rebased to next-20240604
- Link to v5: https://lore.kernel.org/r/[e-mail]

Changes in v5:
- Drop unused regulator and alias for now.
- Fix CHECK_DTB warning.
- Link to v4: https://lore.kernel.org/r/[e-mail]

Changes in v4:
- Sort nodes by address
- Drop coresight nodes
- Align clock rates for SDHC1-3
- Drop wdog3 board specific property
- Link to v3: https://lore.kernel.org/r/[e-mail]

Changes in v3:
- Drop irqsteer node because binding not accepted
- Pass dtbs_check
- Link to v2: https://lore.kernel.org/r/[e-mail]

Changes in v2:
- Addressed Rob and Krzysztof's comments, and fix dts_check issue
  To pass the dtbs_check, need 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 freescale/imx95-19x19-evk.dtb' for [e-mail]:

arch/arm64/boot/dts/freescale/imx95-19x19-evk.dtb: scmi: protocol@19: Unevaluated properties are not allowed ('regusdhc2vmmcgrp', 'uart1grp', 'usdhc1-100mhzgrp', 'usdhc1-200mhzgrp', 'usdhc1grp', 'usdhc2-100mhzgrp', 'usdhc2-200mhzgrp', 'usdhc2gpiogrp', 'usdhc2grp' were unexpected)

Since Linus has applied the pinctrl patchset[1], the check will pass.

Shawn,
In patch 3, there is one minor comment, do you expect me to send v7
or you could help update it?

Thanks,
Peng.
