Hi,

this in an update to the series introducing the basic DT support for the
Allwinner A523 SoC. It now comes with DTs for three boards, using
slightly different packages of that SoC.[1]
Functionality-wise it relies on the pinctrl[2] and clock[3] support
series, though there are no direct code dependency series between the
series. Two binding patches from there are required to pass dtbs_check,
git put their patch IDs in the footer below.
Compared to v2 only small fixes in the NMI controller driver: renaming
the struct to better reflect its new usage, add adding the DS pin to
the eMMC pingroup list. Adding accrued tags on the way, many thanks to
the diligent reviewers! More detailed changelog below.

The first patches add DT binding documentation for the most basic
peripherals, most of them actually being already supported, courtesy of
identical IP being used. This includes MMC and USB 2.0, so with the above
mentioned clock and pinctrl support this gives an already somewhat usable
mainline support for this new SoC family.
The watchdog is not completely compatible, but is an easy addition, so
this bit is included in here as well, the same is true for the NMI
controller, required for delivering PMIC interrupts.

The A523 features 8 Arm Cortex-A55 cores, organised in two clusters,
clocked separately, with different OPP limits, in some kind of
little/LITTLE configuration. The GPU is a Arm Mali G57 MC01, and the chip
also features a single PCIe 2.1 lane, sharing a PHY with some USB 3.1
controller - which means only one of the two can be used.
The rest of the SoC is the usual soup of multimedia SoC IP, with eDP
support and two Gigabit Ethernet MACs among the highlights.

The main feature is patch 08/15, which adds the SoC .dtsi. This for now
is limited to the parts that are supported and could be tested. Compared
to v1 we now have some basic TF-A support, so the PSCI nodes are in now.

The final patches add basic support for the Avaota-A1 router board, the
X96QPro+ TV box, and the Radxa A5E development board.

The mainline firmware side in general is coming together now: we have
basic U-Boot support working (including MMC and USB), most importantly
with proper DRAM support, so no more binary blobs, and some basic TF-A
support.

Please have a look at those DT bits here, ideally compare them to the
available user manual, and test them if you have access to hardware.

Based on v6.14-rc1.
I pushed a branch with all the three series combined here:

Cheers,
Andre

Changelog v2 .. v3:
- split NMI controller register offset into sub-struct
- properly align NMI controller data definition
- adding ACKs from Rob and Jernej (with thanks!)

Changelog v1 .. v2:
- drop USB, I2C, RTC binding patches: already merged
- add tags from reviewers (with thanks!)
- drop unrelated deprecation comment from MMC binding patch
- drop fallback compatible for NMI controller, stands on its own now
- adjust PHY binding to merged A100 binding (dropping tag)
- .dtsi: add secondary cores
- .dtsi: enable PSCI
- .dtsi: move 32K oscillator to board .dts files
- .dtsi: adjust CCU source clocks
- .dtsi: add MMC1 node (typcially for SDIO WiFi)
- .dtsi: add remaining UARTs
- .dtsi: add remaing I2C devices
- add two new board .dts files
- add DT bindings for those two new board names
- avaota.dts: drop reserved memory from (TF-A now in SRAM)
- avaota.dts: drop SD card dummy supply node
- avaota.dts: add eMMC node (shipped on most boards)
- avaota.dts: fix OTG mode, explain situation
- add Chameleon .dts file (depends on YuzukiHD vendor name patch)
