Merge patch series "Switch Apple silicon boards to upstream device trees"

Browse Source 
Janne Grunau <j@jannau.net> says:

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.

- SPI keyboard (on laptops)
- SPI keyboard (on M1 laptops)
- Framebuffer
- NVMe storage
- USB 3.1 Type-C ports
Device trees are currently provided for the M1 Mac mini (2020, J274),
M1 MacBook Pro 13" (2020, J293), M1 MacBook Air (2020, J313) and M1
iMac (2021, J456/J457).
Device trees are provided in dts/upstream/src/arm64/apple/ and available
for all M1 and M2 (t8103, t8112, t600x and t602x) devices.
