[PATCH v6 00/20] 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 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

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.

Patch dependencies:
- A patch to increase the reset delay in the watchdog driver[3] are 
needed on some SoCs to avoid the "Reboot Failed" message. (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.

Changes since v5:
 - Changed how device trees are split. {soc}.dtsi now only contain on-SoC
   parts, and parts common to all devices using a soc is in
   {soc}-common.dtsi. For A9 devices the common .dtsi is
   "s800-0-3-common.dtsi". For A8 devices additonally there is
   "t7000-handheld.dtsi" to group iPhones, iPad and iPod touches from
   Apple TVs.
 - For other SoCs, either all devices are handheld or there are only one
   type of handheld devices using it, so no handheld .dtsi is needed.
 - This is closer to how the existing device trees are split, and will
   allow nodes likes power manager and battery to be added more easily.
 - Fixed Apple TV HD serial debug console. It is serial6, not serial0.

Changes since v4:
  - Removed incorrect commit message about the order of CPU cores
    in the commit adding Apple A7-A11 CPU cores.
  - Update tags on commit added A8X device tree files, requested by
    Markuss.

Changes since v3:
  - Properly seperate A10X dt-binding additions and dts additions.
  - Apple CPU cores, including the existing ones are now ordered
    alphabetically.

Changes since v2:
  - Removed A10 cpufreq. The loader may be missing some initialization
    code that just happened to be performed by some versions of the
    firmware as well, given the inconsistent behavior on different
    devices. It is also possible that the driver needs to be modified,
    I do not know and this needs more research first.

  - Removed Ivaylo's tags on commit to add A8X device trees, seems he
    does not want those anymore[4].
  - Added Ivaylo's tags on commit to add A8 device tree, I have missed
    the tag. See [5] for source of those tags.
  - Added Conor's missing A-b on the commit to add A7 machine bindings.

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.
