[PATCH v4 0/3] SPMI dt-bindings and nodes for Apple A11 and T2 SoCs

[PATCH v4 0/3] SPMI dt-bindings and nodes for Apple A11 and T2 SoCs

[Nick Chan]

Hi,

This series adds dt-bindings and nodes for Apple A11 and T2 SoCs,
and the existing driver appears to be compatible. Drivers for the attached
Dialog DA2422 and DA2449 PMICs will be in a future patch series.

The dt-binding patch depends on other spmi dt-binding patches that are
already applied in apple-soc/drivers-6.18, so it is best for it to be
applied through there.

Changes in v4:
- Keep the empty lines as is in the spmi dt-bindings file
- Keep DT includes in alphabetical order
- Drop tags for dt-bindings since they are sigificantly different from v2
- Link to v3: https://lore.kernel.org/r/20250829-t8015-spmi-v3-0-58b15ee2c825@gmail.com

Changes in v3:
- After discussion with the DT maintainers we agreed not to extend the
  generic compatible[1]. Change the series to the agreed-upon style.
- Now depends on a patch[2] adding the t602x spmi compatible.
- Link to v2: https://lore.kernel.org/r/20250811-t8015-spmi-v2-0-a291acf0d469@gmail.com

Changes in v2:
- Rebased on top of v6.17-rc1
- Collect Rob and Sven's tags
- Link to v1: https://lore.kernel.org/r/20250609-t8015-spmi-v1-0-b3c55ad01491@gmail.com

[PATCH v4 1/3] dt-bindings: spmi: Add Apple A11 and T2 compatible

[Nick Chan]

The SPMI bus found on Apple A11 and T2 SoCs are compatible with the
existing driver for t8103's spmi so add their compatibles.

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.

As stated in cover letter, the tags are dropped in v4 because the dt-binding patch has changed
significantly from v2. (really should be dropped in v3 though but that did not happen). And this
is actually a different patch from v3, the only difference is a newline is no longer removed.
