arm64: tegra: Device tree changes for v6.3-rc1
There are two big changes in this: one is to bump the #address-cells and
the #size-cells properties to 2 so that bus address translations work
correctly and another to sort nodes according to a scheme that we've
been trying to follow, but where some inconsistencies have accumulated
over the years.
As for the rest, this adds mostly new things on Tegra234, such as USB
host and device support and identification EEPROMs found on Jetson AGX
Orin.
Some cleanups are also included, such as the removal of unneeded
properties or duplicated nodes.

RISC-V Devicetrees for v6.3-mw0
Microchip:
A vendor prefix for Aldec and both a binding and Devicetree for the
Aldec TySoM devkit for PolarFire SoC. This Devicetree corresponds to
what they are shipping in the SDK for rev2 boards.
StarFive:
Just the binding for the new StarFive JH7110 SoC and its first-party
SDC the VisionFive 2.
Other:
I was expecting the Devicetree for the aforementioned board to be ready
for this window, as the pinctrl driver had seem some review prior to
v6.2 and both it & the base clock drivers are heavily based on the
existing drivers for the JH7110.
That didn't come to be.. Christmas, the RISC-V Summit in December and
the Lunar New Year all playing a part perhaps.
Because of that, both Palmer and I have the Kconfig.socs work in our
branches, although in hindsight it probably wasn't needed here as I
only added the TySoM Devicetree & the conflict would've been trivial.

Allwinner manufactures the sunxi family of application processors. This
includes the "sun8i" series of ARMv7 SoCs, the "sun50i" series of ARMv8
SoCs, and now the "sun20i" series of 64-bit RISC-V SoCs.
The first SoC in the sun20i series is D1, containing a single T-HEAD
C906 core. D1s is a low-pin-count variant of D1 with co-packaged DRAM.
Most peripherals are shared across the entire chip family. In fact, the
ARMv7 T113 SoC is pin-compatible and almost entirely register-compatible
with the D1s.
This means many existing device drivers can be reused. To facilitate
this reuse, name the symbol ARCH_SUNXI, since that is what the existing
drivers have as their dependency.

The MangoPi MQ is a tiny SBC built around the Allwinner D1s. Its
onboard peripherals include two USB Type-C ports (1 device, 1 host)
and RTL8189FTV WLAN.
A MangoPi MQ-R variant of the board also exists. The MQ-R has a
different form factor, but the onboard peripherals are the same.
Most D1 and D1s boards use a similar power tree, with the 1.8V rail
powered by the SoC's internal LDOA, analog domains powered by ALDO,
and the rest of the board powered by always-on fixed regulators. To
avoid duplication, factor out the regulator information that is
common across boards.
The board also exposes GPIO Port E via a FPC connector, which can
support either a camera or an RMII Ethernet PHY. The additional
regulators supply that connector.

D1 (aka D1-H), D1s (aka F133), R528, and T113 are a family of SoCs based
on a single die, or at a pair of dies derived from the same design.
D1 and D1s contain a single T-HEAD Xuantie C906 CPU, whereas R528 and
T113 contain a pair of Cortex-A7's. D1 and R528 are the full version of
the chip with a BGA package, whereas D1s and T113 are low-pin-count QFP
variants.
Because the original design supported both ARM and RISC-V CPUs, some
peripherals are duplicated. In addition, all variants except D1s contain
a HiFi 4 DSP with its own set of peripherals.
The devicetrees are organized to minimize duplication:
- Common perhiperals are described in sunxi-d1s-t113.dtsi
- DSP-related peripherals are described in sunxi-d1-t113.dtsi
- RISC-V specific hardware is described in sun20i-d1s.dtsi
- Functionality unique to the D1 variant is described in sun20i-d1.dtsi
The SOC_PERIPHERAL_IRQ macro handles the different #interrupt-cells
values between the ARM (GIC) and RISC-V (PLIC) versions of the SoC.

The Bananapi-M3 has a SATA connector, driven by a USB-to-SATA bridge
soldered on the board. The power for the SATA device is provided by a
GPIO controlled regulator. Since the SATA device is behind USB, it has
no DT node, so we never described this regulator. Instead U-Boot was
turning this on in a rather hackish way, which we now want to get rid of.
On top of that it seems fragile to leave this GPIO undescribed, as
userland could claim it and turn the disk off.
Add a fixed regulator, controlled by the PD25 GPIO, and mark it as
always-on. This would mimic the current situation, but in a safer way,
and would allow U-Boot to drop the CONFIG_SATAPWR enable hack.

Due to the part shortage, the AR8031 PHY was replaced with a Micrel
KSZ9131. Hard-coding the ID of the PHY makes this new PHY
non-operational on newer hardware. Since previous hardware had only
shipped to a limited number of people, and they have not gone to

The board used to originally introduce the Beacon Embedded RZ/G2[M/N/H]
boards had a GPIO expander with address 20, but this was changed when
the final board went to production.
The production boards changed both the part itself and the address.
With the incorrect address, the LCD cannot come up. If the LCD fails,
the rcar-du driver fails to come up, and that also breaks HDMI.
Pre-release board were not shipped to the general public, so it should
be safe to push this as a fix. Anyone with a production board would
have video fail due to this GPIO expander change.

ALSA SoC has many types of Generic Audio Card drivers (Simple Audio
Card, Audio Graph Card, Audio Graph Card2), and Renesas/Kuninori
Morimoto wants to test these.
The Generic Audio Card driver had been requested on ALSA SoC.
It supports many types of device connection methods, and historically,
the requested connection support range of the generic driver has been
upgraded.
Upgrading the connection support range itself could not be implemented
in the generic driver, because we need to keep compatibility with old
DTBs. This is one of the reasons why we have many types of Generic Audio
Card driver.
The ULCB/KF combo is a good board stack to test these.
Kuninori has been testing these Generic Audio Card drivers by using his
local patches to switching drivers. But from an information sharing
point of view, it is a good idea to upstream these, because the DT
configuration is complex. Hence this can be a good sample for the user.
Hence add a "Simple Audio Card + MIXer + TDM Split" DT setting file for
ULCB/KF. Because of the limited number of subdevices, the HDMI output
is ignored.
This setting can be enabled by updating ulcb.dtsi / ulcb-kf.dtsi.
From a normal user point of view who doesn't need to test the driver,
everything should stay as-is, and nothing changes.
Note that because this needs "switching driver", and not "adding extra
feature", this does not use a Device Tree overlay.

ALSA SoC has many types of Generic Audio Card drivers (Simple Audio
Card, Audio Graph Card, Audio Graph Card2), and Renesas/Kuninori
Morimoto wants to test these.
The Generic Audio Card driver had been requested on ALSA SoC.
It supports many types of device connection methods, and historically,
the requested connection support range of the generic driver has been
upgraded.
Upgrading the connection support range itself could not be implemented
in the generic driver, because we need to keep compatibility with old
DTBs. This is one of the reasons why we have many types of Generic Audio
Card driver.
The ULCB/KF combo is a good board stack to test these.
Kuninori has been testing these Generic Audio Card drivers by using his
local patches to switching drivers. But from an information sharing
point of view, it is a good idea to upstream these, because the DT
configuration is complex. Hence this can be a good sample for the user.
Hence add an "Audio Graph Card2" DT setting file for ULCB/KF,
and switch to use it. You can switch to a different Generic Audio Graph
driver by updating ulcb.dtsi / ulcb-kf.dtsi.
From a normal user point of view who doesn't need to test the driver,
everything should stay as-is, and nothing changes.
Note that because this needs "switching driver", and not "adding extra
feature", this does not use a Device Tree overlay.
