[PATCH v2 00/12] riscv: Allwinner D1/D1s platform support

[PATCH v2 00/12] riscv: Allwinner D1/D1s platform support

[Samuel Holland]

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:
 - In-package LDO regulators:
   https://lore.kernel.org/lkml/20221125040112.18160-1-samuel@sholland.org/
 - Ethernet MAC binding fixes (not a new issue with D1):
   https://lore.kernel.org/lkml/20221125202008.64595-1-samuel@sholland.org/
 - RTL8723DS Bluetooth (has driver support, missing documentation):
   https://lore.kernel.org/lkml/20221125040956.18648-1-samuel@sholland.org/
 - TI ADC101C ADC (has driver support, missing documentation):
   https://lore.kernel.org/lkml/20221125220903.8632-1-samuel@sholland.org/

The only remaining DT validation issue is that gpio-fan is missing a
YAML conversion, although one is on the list here:

I tested this series (DMIC, Ethernet, LEDs, MMC, PMIC, touch, and USB,
all where available) on the following boards:
 - sun20i-d1-devterm-v3.14
 - sun20i-d1-dongshan-nezha-stu
 - sun20i-d1-lichee-rv-86-panel-480p
 - sun20i-d1-mangopi-mq-pro
 - sun20i-d1-nezha
 - sun20i-d1s-mangopi-mq

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

[PATCH v2 01/12] MAINTAINERS: Match the sun20i family of Allwinner SoCs

[Samuel Holland]

Allwinner sunxi SoCs with a RISC-V CPU use the sun20i designator. Match
that pattern in addition to the designators for 32 and 64-bit ARM SoCs.

[PATCH v2 04/12] riscv: dts: allwinner: Add the D1/D1s SoC devicetree

[Samuel Holland]

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.

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

[PATCH v2 05/12] riscv: dts: allwinner: Add MangoPi MQ devicetree

[Samuel Holland]

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.

[PATCH v2 06/12] riscv: dts: allwinner: Add Allwinner D1 Nezha devicetree

[Samuel Holland]

"D1 Nezha" is Allwinner's first-party development board for the D1 SoC.
It was shipped with 512M, 1G, or 2G of DDR3. It supports onboard audio,
HDMI, gigabit Ethernet, WiFi and Bluetooth, USB 2.0 host and OTG ports,

[PATCH v2 07/12] riscv: dts: allwinner: Add Sipeed Lichee RV devicetrees

[Samuel Holland]

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.

Co-developed-by: Jisheng Zhang <jszhang@kernel.org>

Changes in v2:
 - Added DMIC sound card to Lichee RV dock and Lichee RV 86 Panel
 - Removed LRADC (depends on analog LDOs)

[PATCH v2 08/12] riscv: dts: allwinner: Add MangoPi MQ Pro devicetree

[Samuel Holland]

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.

Changes in v2:
 - Added LED (GPIO shared between onboard LED and backlight regulator)

[PATCH v2 09/12] riscv: dts: allwinner: Add Dongshan Nezha STU devicetree

[Samuel Holland]

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.

[PATCH v2 10/12] riscv: dts: allwinner: Add ClockworkPi and DevTerm devicetrees

[Samuel Holland]

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.

[PATCH v2 11/12] riscv: Add the Allwinner SoC family Kconfig option

[Samuel Holland]

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.

[PATCH v2 12/12] riscv: defconfig: Enable the Allwinner D1 platform and drivers

[Samuel Holland]

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.

Is this "additionally contain" or a case of the D1 is the R528 but with
s/arm/riscv/? It's the latter, right?

Since this is a "must", can you drop the clock-frequency = <0> here so
that if someone doesn't override it in their board dt-validate
complains?

Thanks,

Does this need to have the if MMU? I thought it only needed the
!XIP_KERNEL since the PMU errata does not depend on MMU.

Or have a missed some patch elsewhere that'll change that?

> +	select SIFIVE_PLIC

This is v6.3 material right? One of the things that should be going for
v6.3 is all of these select SIFIVE_PLICs. Palmer suggested putting up an
immutable branch for any of that cleanup that intersects with new
platforms, so I'll probably send one out at some stage.

Thanks,
Conor.

All of that looks good.

This I am not sure about though. I'll leave that to Palmer since I'm
pretty sure it was him that said it, but I thought the plan was only
turning on stuff required to boot to a console & things that are
generally useful rather than enabling modules for everyone's "random"
drivers. Palmer?

rest matches what we already have in other SoCs.

I noticed two things, though, mentioned inline below:

The clocks and the two mixers are not children of a bus node anymore,
IIUC correctly this was to manage the SRAM control. Is that now handled
differently, or does the D1 generation not require this anymore?

This is the same interrupt number as for the DSI controller above. Is
that correct, and can the drivers handle that?

The D1 family uses the DSP SRAM for extra space during early boot --
this applies even to D1s, where the DSP is fused off. Since the DE SRAM
is not used for this purpose, the "SRAM C" aka "boot mode" bit in the
SRAM controller is cleared by default, thus mapping the DE SRAM to the
peripheral. So the DE works without touching the syscon registers.

However, if I set the SRAM C bit, the DE stops working. So having the
bus node would make some sense. But I do not know any address for the
SRAM -- there is no "boot" address, and the "peripheral" address may not
even be accessible to the CPU. So it is not possible to represent this
with a mmio-sram node like the binding requires.

So I suppose we should either change the binding to allow a child
allwinner,sun50i-a64-sram-c node with no address (the driver should work
fine with this); or leave out the bus, and people who go poking around
in the syscon registers get to keep the pieces. :)

Yes, it is correct. Currently, neither driver uses the interrupt, so we
will just need to keep the sharing in mind if/when that happens.

The D1-H user manual says starting from interrupt number 176, interrupts are
CPUX related which I assume are CPU internal interrupts?

If yes, for external ones, valid interrupt source range is [1, 175]. And this
field should be 175, no?

While the overall dt looks good to me, it seems others did find
some minor issues. But I can at least provide a

Tested-by: Heiko Stuebner <heiko.stuebner@vrull.eu>

as it could sucessfully boot the Nezha variant of boards for me.

That sounds like a better variant.

The D1 / C906 _needs_ the errata for the memory handling
and the other alternative constraints require the !XIP

With the select, a xip-kernel would not boot at all on a D1

Isn't the defconfig meant as a starting point to get working systems
with minimal config effort? At least that was always the way to go on arm
so far :-) .

So having boot-required drivers built-in with the rest enabled as modules
for supported boards will allow people to boot theirs without headaches.

Disabling unneeded drivers if you're starved for storage space in a special
project is always easier than hunting down all the drivers to enable for a
specific board.

I wouldn't mind being able to turn on all the PolarFire SoC stuff and
yeah, that would be the way that arm64 does it. But I do recall hearing
that I should not turn stuff on this way, when I initially tried to
turn stuff on via selects, got a nack and asked if I could do this instead.

But it may be that I misremember, which is why I appealed to the Higher
Powers for clarification :)

FWIW, I don't worry too much about modules in defconfig because I always
immediately apply a 'LSMOD=$PWD/L localmodconfig' to it, where the L
file is an lsmod output which only includes modules I need.

idk, defconfig to me is not about you or I, it's about A Developer that gets an SBC or a devkit and their experience.
Or alternatively, someone's CI ;)
I'd like to put everything in, but I recall that being shot down, that's all.

The whole "who is defconfig for" discussion always ends up kind of 
vague, but IIUC it's generally aimed at kernel hackers as opposed to end 
users -- so it's not meant to be a disto config, that's why we have 
things like the debug options turned on.  I tend to think of it as a "if 
a patch submitter is going to test only one config, then what do I want 
in it?" and let that determine what goes in defconfig.

IMO having defconfig contain the drivers necessary to boot every common 
dev board as =y, and having =m for anything else on those boards also 
seem reasonable.  That will make the transition from vendor/distro 
kernels to upstream a bit smoother, which is always good.  I guess 
there's some slight build time and image size issues, but aside from 
some very small systems that shouldn't be too bad for kernel developers 
-- and if we really end up with another popular system with 6MiB of RAM 
we can just stick another tiny defconfig in there for it.

I actually don't use modules when doing kernel development because I 
find it easier to track things when they're packed into a single binary, 
but I don't think it's necessary to steer everyone that way.

Adding some of the Arm folks here, in case they have thoughts.  The best 
bet is probably to try and do something similar, though my worry is that 
the answer is something like "target standard platforms" and we don't 
have any.

I think this is handled very inconsistently across architectures. On
32-bit arm, we used to have a board specific defconfig for each machine,
but of course that never scaled to the number of supported machines.

The important defconfig files we have these days are the arm64
one, and on arm32 we have the ones that are mutually incompatible,
in particular one for armv7 and one for armv5, each enabling as
many machines as possible, plus usually one per SoC vendor that
is more specialized.

If you want to formalize it a bit more than this,  I would recommend
having more fragments, e.g. one for typical debugging options,
one for things that are needed to boot both Fedora and Debian
userland, etc.

Yes, this is also the guideline for arm64. On top of that it's supposed
to be a sane common config to be used to reproduce bugs. A common
question from maintainers is "Does it happen with defconfig?". If not,
what does it take on top of defconfig to get there?
The idea is that people can run the same config and thus the same image
on *their* boards, regardless of the particular platform.

Originally arm64 included most drivers as [=y], but this grew too big
quickly, so it was scaled back to be able to boot from the board's mass
storage (SD card, SATA, NVMe), with non-essential drivers included as
modules. And yes, most people just build and use the Image, which keeps
the build effort reasonable.
Also required features to make systemd happy, and to enable other core
distro features, were included, so that such kernels can boot distro
userland without losing significant functionality.

No such thing on arm64 either :-(
