[PATCH 00/22] Initial device trees for A7-A11 based Apple devices

[Nick Chan]

Hi,

This series adds device trees for all A7-A11 SoC based iPhones, iPads,
iPod touches and Apple TVs.

The following devices has been excluded from this series:
  - All T2 devices (A10-based): bootloader does not work (yet)
  - HomePod: Not tested, and it's also a different form factor

This series supports the following on all devices:
- SMP (spin-table)
- UART
- simple-framebuffer
- watchdog
- timer
- pinctrl
- AIC interrupts

The following is supported on A7-A10:
- gpio-keys
The buttons on A11 based devices like the iPhone X is a SMC subdevice,
and cannot be supported in this way.

The following is supported on A10:
- cpufreq

A10(X) has performance and efficiency core pairs that act as single logical
cores, and only one type of core can be active at a given time. This results
in a core that suddenly have its capacity lowered in low p-states,
so the frequencies of the low p-states must be adjusted.

Patch dependencies:
- The required AIC patches[1] has been sitting in linux-next since
next-20240906, through the tip tree.
- The important serial fixes[2] will go through the samsung tree and should
be in good shape though those have not been merged.
- The optional patch to disable 32-bit EL0 on A10(X)[3] has not received
any comments (v1 or v2).

Authorship information:
- The commits to actually add the dts files are mostly made by Konard,
and Konard's sign-off is added by me with permission. I also updated the
Konrad's email in the actual dts files. Konrad can confirm this.

- Everything else is entirely made by me, including the cpufreq additions
into the dts file for A10.
