[PATCH v2 00/11] arm64: dts: imx95: various updates

[Peng Fan]

This patchset is to upstream various downstream changes.
- Correct edma channel for lpuart7/8
- Add System Counter, SCMI LMM/CPU, V2X MU, coresight nodes
- Update alias
- Add pca9632, pf09/pf53 thermal and etc.

dtbs_check will report a few failures, such as linux,code, db suffix.
The failures are not related to this patchset.

Signed-off-by: Peng Fan <peng.fan@nxp.com>

Changes in v2:
- Drop patch 8 because dt-bindings not ready, and patch 12
- Per Frank's comments: Typo fixes, node name updates, sort properties
- Add R-b from Frank
- There is still dtbs_check error, but not related to this patchset, it
is because https://lore.kernel.org/imx/20250718094723.3680482-1-peng.fan@nxp.com/
not applied.
- Link to v1: https://lore.kernel.org/r/20250815-imx9-dts-v1-0-e609eb4e3105@nxp.com

[PATCH v2 01/11] arm64: dts: imx95: Correct the lpuart7 and lpuart8 srcid

[Peng Fan]

From: Joy Zou <joy.zou@nxp.com>

According to the imx95 RM, the lpuart7 rx and tx DMA's srcid are 88 and 87,
and the lpuart8 rx and tx DMA's srcid are 90 and 89. So correct them.

[PATCH v2 08/11] arm64: dts: imx95-19x19-evk: Add Tsettle delay in m2 regulator

[Peng Fan]

From: Richard Zhu <hongxing.zhu@nxp.com>

M.2 device only can be enabled after all Power Rails reach their minimum
operating voltage (PCI Express M.2 Specification r5.1 3.1.4 Power-up
Timing). Set a delay equal to the max value of Tsettle in m2 regulator.

[Peng Fan]

System Manager supports reading out pf09 and pf53 temperature and
SCMI Agent could get the values through SCMI sensor protocol. So add
the nodes to allow Linux to get the temperature.

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


This patch series was applied (using b4) to base:
 Base: base-commit ff837884a4642382a24d10fd503acf2c3a472f10 not known, ignoring
 Base: attempting to guess base-commit...
 Base: tags/next-20250818 (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

New warnings running 'make CHECK_DTBS=y for arch/arm64/boot/dts/freescale/' for 20250818-imx9-dts-v2-0-8ba787fb5280@nxp.com:
