Merge patch series "Initial Apple M3 Pro, Max and Ultra device trees"

Janne Grunau <j@jannau.net> says:

This series adds device trees for Apple silicon devices with M3 Pro, Max
and Ultra SoCs. The M3 generation has fewer devices than their M1 and M2
predecessors. The only non-laptop device is the M3 Ultra Mac Studio. The
Laptops are the known 14 and 16-inch Macbook Pros now with M3 Pro and
M3 Max SoCs. The M3 Max variant with fewer CPU and GPU cores has
additionally only a 384-bit wide memory bus instead of 512-bit of the
full M3 Max. It has a separate identifier (T6034) and so there are six
laptop device trees.
Another difference to M1 and M2 Pro/Max/Ultra is that the M3 Pro is
distinct SoC design and not a smaller M3 Max. For this reason both M3
Max variants and the M3 Ultra will use "apple,t6030" as compatible
prefix. In the M1 and M2 generations Pro, Max and Ultra SoCs shared
"apple,t6000" / "apple,t6020" as common prefix. There is currently no
known difference but M3 Pro and M3 Max are not as closely related as
previously.

This series adds the same level of hardware as the base M3 (T8122) has
in v7.2-rc1. This includes CPU cores, interrupt controller, power
states, watchdog, serial, pin controller, i2c and the boot framebuffer.
This is intended as base so that support for additional hardware can be
added to all M3 based devices at the same time.
