This series adds the Kconfig/defconfig plumbing and devicetrees for a
range of Allwinner D1 and D1s-based boards. Many features are already
enabled, including USB, Ethernet, and WiFi.
The devicetrees use bindings from the following series which have not
yet been merged to linux-next:
- In-package LDO regulators:
https://lore.kernel.org/lkml/[email protected]/
- Ethernet MAC binding fix (not a new issue with D1):
https://lore.kernel.org/lkml/[email protected]/
The only remaining DT validation issue is that gpio-fan is missing a
YAML conversion, although one is on the list here (v2):
https://lore.kernel.org/lkml/[email protected]/

Note that validation requires dt-schema v2022.12 or newer.
I thoroughly tested earlier versions of this series (DMIC, Ethernet,
LEDs, MMC, PMIC, touch, and USB, where available) on several boards.
v4 has only trivial changes, and I boot-tested it on sun20i-d1-nezha.
This series is pretty much just waiting on the regulator binding to
land. I do not expect to send another version. For the rest of the
hardware blocks, DT additions will be based on top of this series.
Changes in v4:
- Rebase on v6.2-rc1 + soc2arch-immutable
- Drop the now-redundant 'select SIFIVE_PLIC'
Changes in v3:
- Drop dummy DCXO clock-frequency property
- Decrease the PLIC's riscv,ndev property to 175
- Fix `make W=1 dtbs` warnings (unnecessary #address/#size-cells)
- Drop mmc aliases
- Change LED_FUNCTION_BACKLIGHT to LED_FUNCTION_STATUS (the backlight
regulator is disconnected by default, so this is a standalone LED)
- Fix `make W=1 dtbs` warnings (missing reg properties)
- ARCH_SUNXI depends on MMU && !XIP_KERNEL
Changes in v2:
- Add MangoPi MQ (non-Pro) board
- Split into separate files for sharing with D1s/R528/T113
- Use SOC_PERIPHERAL_IRQ macro for interrupts
- Rename osc24M to dcxo and move the frequency to the board DTs
- Drop analog LDOs due to the missing binding
- Correct tcon_top DSI clock reference
- Add DMIC, DSI controller, and DPHY (bindings are in linux-next)
- Add CPU OPP table
- Common regulators moved to MangoPi MQ patch, removed analog LDOs
- Removed LRADC (depends on analog LDOs)
- Added XR829 host-wake interrupt
- Added DMIC sound card to Lichee RV dock and Lichee RV 86 Panel
- Removed LRADC (depends on analog LDOs)
- Added LED (GPIO shared between onboard LED and backlight regulator)
- Added PMIC GPIO controller node (binding merged for 6.2)
- Sort Kconfig as if we had done s/SOC_/ARCH_/ for future-proofing

2.37.4
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.

2.37.4
Sipeed manufactures a "Lichee RV" system-on-module, which provides a
minimal working system on its own, as well as a few carrier boards. The
"Dock" board provides audio, USB, and WiFi. The "86 Panel" additionally
provides 100M Ethernet and a built-in display panel.
The 86 Panel repurposes the USB ID and VBUS detection GPIOs for its RGB
panel interface, since the USB OTG port is inaccessible inside the case.

2.37.4
The MangoPi MQ Pro is a tiny SBC with a layout compatible to the
Raspberry Pi Zero. It includes the Allwinner D1 SoC, 512M or 1G of DDR3,
and an RTL8723DS-based WiFi/Bluetooth module.
The board also exposes GPIO Port E via a connector on the end of the
board, which can support either a camera or an RMII Ethernet PHY. The
additional regulators supply that connector.

(no changes since v3)
Changes in v3:
- Drop mmc alias
- Change LED_FUNCTION_BACKLIGHT to LED_FUNCTION_STATUS (the backlight
regulator is disconnected by default, so this is a standalone LED)
Changes in v2:
- Added LED (GPIO shared between onboard LED and backlight regulator)

2.37.4
The 100ask Dongshan Nezha STU is a system-on-module that can be used
standalone or with a carrier board. The SoM provides gigabit Ethernet,
HDMI, a USB peripheral port, and WiFi/Bluetooth via an RTL8723DS chip.
The "DIY" carrier board exposes almost every pin from the D1 SoC to 0.1"
headers, but contains no digital circuitry, so it does not have its own
devicetree.

2.37.4
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.

Now that several D1-based boards are supported, enable the platform in
our defconfig. Build in the drivers which are necessary to boot, such as
the pinctrl, MMC, RTC (which provides critical clocks), SPI (for flash),
and watchdog (which may be left enabled by the bootloader). Other common
onboard peripherals are enabled as modules.

2.37.4
Clockwork Tech manufactures several SoMs for their RasPi CM3-compatible
"ClockworkPi" mainboard. Their R-01 SoM features the Allwinner D1 SoC.
The R-01 contains only the CPU, DRAM, and always-on voltage regulation;
it does not merit a separate devicetree.
The ClockworkPi mainboard features analog audio, a MIPI-DSI panel, USB
host and peripheral ports, an Ampak AP6256 WiFi/Bluetooth module, and an
X-Powers AXP228 PMIC for managing a Li-ion battery.
The DevTerm is a complete system which extends the ClockworkPi mainboard
with a MIPI-DSI panel and a pair of expansion boards. These expansion
boards provide a fan, a USB keyboard, speakers, and a thermal printer.

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.

(no changes since v3)
Changes in v3:
- Drop dummy DCXO clock-frequency property
- Decrease the PLIC's riscv,ndev property to 175
- Fix `make W=1 dtbs` warnings (unnecessary #address/#size-cells)
Changes in v2:
- Split into separate files for sharing with D1s/R528/T113
- Use SOC_PERIPHERAL_IRQ macro for interrupts
- Rename osc24M to dcxo and move the frequency to the board DTs
- Drop analog LDOs due to the missing binding
- Correct tcon_top DSI clock reference
- Add DMIC, DSI controller, and DPHY (bindings are in linux-next)
- Add CPU OPP table

Looks like the panel-enabled variants would better be described as device-tree
overlays as they are not specific devices but are peripheral extensions.
What do you think?

I don't agree. The Lichee RV 86 Panel is sold as a complete unit, with
the SoM+board and LCD pre-assembled inside a case. It is not possible to
purchase the board without a panel, so the panel-enabled variants are
the only variants.

Oh my bad, I didn't go as far as actually checking what it looks like.
So yeah if it's an individual device on its own I agree it deserves its
own dedicated device-tree.
