[PATCH v3 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.

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

[PATCH v3 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.
