[PATCH v2 00/22] Initial device trees for A7-A11 based Apple devices

[Nick Chan <towinchenmi@xxxxxxxxx>]

Hi,

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

The following devices have 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

To pass `make dtbs_check`, please install the latest dtschema from the main
branch, for the `television` chassis type.

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:
- Buttons and switches (with pinctrl)
The buttons on A11 based devices like the iPhone X is a subdevice of the
not yet supported SMC.

The following is supported on A10:
- cpufreq

A10 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] has been sitting in linux-next since
next-20240913, through the tty tree.
- The optional patch to disable 32-bit EL0 on A10(X)[3] has not received
any comments (v1 or v2).
- A trivial patch to increase the reset delay in the watchdog driver[4]
are needed on some SoCs to avoid the "Reboot Failed" message. It has
been reviewed. (The system will reset regardless of the patch)

Authorship information:
- The commits to actually add the dts files are mostly made by Konrad,
and Konrad'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.

Changes since v1:
  - Added /chassis-type property
  - Added opp-microvolt in A10 cpufreq for documentation purposes
  - Home button is now assigned KEY_HOMEPAGE
  - Fixed t8010-n112.dts and do not remove it from Makefile in later
    commits... (iPod touch 7)

In order to be consistent with the Apple ARM Machines bindings,
the order of dt-bindings did not change from v1.

The sort order logic here is having SoC type families in release
order, and SoCs within each family in release order:
    
- t8xxx/t700x/s5l8960x (Apple HxxP/G series, "phone"/"tablet" chips)
   - s5l8960x (Apple H6/A7)
   - t7000 (Apple H7P/A8)
   - t7001 (Apple H7G/A8X)
   - s8000/3 (Apple H8P/A9)
   - s8001 (Apple H8G/A9X)
   - t8010 (Apple H9P/A10)
   - t8011 (Apple H9G/A10X)
   - t8015 (Apple H10/A11)
   - t8103 (Apple H13G/M1)
   - t8112 (Apple H14G/M2)
- t6xxx (Apple HxxJ series, "desktop" chips)
   - t6000 (Apple H13J(S)/M1 Pro)
   - t6001 (Apple H13J(C)/M1 Max)
   - t6002 (Apple H13J(D)/M1 Ultra)

At this moment, it is expected that most hardware blocks will be 100%
compatible between A-series and AX-series SoCs, though to a less extent
than compatibility between desktop chips of the same generation.
