[PATCH v2 0/3] Switch Apple silicon boards to upstream device trees

[Janne Grunau]

The Linux device trees for Apple silicon devices cover now most of the
hardware as u-boot's internal device trees for M1 devices. Linux has in
addition device trees M2 and M1 and M2 Pro/Max/Ultra devices which were
never added in u-boot.
The most common use case for u-boot on Apple silicon devices does not
use DTBs from u-boot but passes runtime modified device trees from an
earlier boot loader (m1n1).
This change regresses support for the SPI on M1 and M1 Pro/Max notebooks
as SPI keyboard support is not in upstream Linux. This regression is in
my opinion acceptable due to the limited use of u-boot's DTBs for these
targets.

Changes in v2:
- Add CONFIG_OF_UPSTREAM_BUILD_VENDOR=y and
  CONFIG_OF_UPSTREAM_VENDOR="apple" to build all apple DTBs
- rebased onto v2026.07-rc1 for Linux v7.0 based DTs in dts/upstream
- Link to v1: https://patch.msgid.link/20260430-apple-dt-upstream-v1-0-dda66c16e0da@jannau.net
