[PATCH v3 00/15] arm64: dts: allwinner: Add basic Allwinner A523 support

[Andre Przywara]

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:

Andre

[PATCH v3 01/15] dt-bindings: mmc: sunxi: Simplify compatible string listing

[Andre Przywara]

New Allwinner SoCs only occasionally update their MMC IP, leading to many
pairs of compatible strings, though there are sometimes a number of them
being compatible with one particular SoC.

Collate the compatible string listing in the binding, to group those
being compatible together. This makes the list more readable, and allows
for easier addition of new SoC's MMC devices.

[PATCH v3 02/15] dt-bindings: mmc: sunxi: add compatible strings for Allwinner A523

[Andre Przywara]

The Allwinner A523 uses the same MMC IP as the D1.

Introduce the new specific compatible strings, and use them with
fallbacks to the D1 strings.

[PATCH v3 03/15] dt-bindings: watchdog: sunxi: add Allwinner A523 compatible string

[Andre Przywara]

The Allwinner A523 SoC features a watchdog similar to the one used in
previous SoCs, but moves some registers around (by just one word), making
it incompatible to existing IPs.

Add the new name to the list of compatible string, and also to the list
of IP requiring two clock inputs.

[PATCH v3 04/15] watchdog: sunxi_wdt: Add support for Allwinner A523

[Andre Przywara]

The Allwinner A523 SoC comes with a watchdog very similar to the ones in
the previous Allwinner SoCs, but oddly enough moves the first half of its
registers up by one word. Since we have different offsets for these
registers across the other SoCs as well, this can simply be modelled by
just stating the new offsets in our per-SoC struct.
The rest of the IP is the same as in the D1, although the A523 moves its
watchdog to a separate MMIO frame, so it's not embedded in the timer
anymore. The driver can be ignorant of this, because the DT will take
care of this.

Add a new struct for the A523, specifying the SoC-specific details, and
tie the new DT compatible string to it.

[PATCH v3 05/15] dt-bindings: irq: sun7i-nmi: document the Allwinner A523 NMI controller

[Andre Przywara]

The Allwinner A523 SoC contains an NMI controller very close to the one
used in the recent Allwinner SoCs, but it adds another bit that needs to
be toggled to actually deliver the IRQs. Sigh.

Add the A523 specific name to the list of allowed compatible strings.

[PATCH v3 06/15] irqchip/sunxi-nmi: Support Allwinner A523 NMI controller

[Andre Przywara]

The NMI controller in the Allwinner A523 is almost compatible to the
previous versions of this IP, but requires the extra bit 31 to be set in
the enable register to actually report the NMI.

Add a mask to allow such an enable bit to be specified, and add this to
the per-SoC data structure. As this struct was just for different register
offsets so far, it was consequently named "reg_offs", which is now no
longer applicable, so rename this to the more generic "data" on the way,
and move the existing offsets into a struct of its own.

Also add the respective Allwinner A523 compatible string, and set bit 31
in its enable mask, to add support for this SoC.

[PATCH v3 07/15] dt-bindings: phy: document Allwinner A523 USB-2.0 PHY

[Andre Przywara]

The Allwinner A523 SoC contains a USB-2.0 PHY fully compatible to the
one used in the D1/T113s SoCs. This PHY controls the two USB-2.0 ports,
there is a separate and quite different PHY for the USB-3.0 port.

Add the new compatible string, with a fallback to the D1 version.

[PATCH v3 08/15] arm64: dts: allwinner: Add Allwinner A523 .dtsi file

[Andre Przywara]

The Allwinner A523, and its siblings A527 and T527, which share the same
die, are a new family of SoCs introduced in 2023. They features eight
Arm Cortex-A55 cores, and, among the other usual peripherals, a PCIe and
USB 3.0 controller.

Add the basic SoC devicetree .dtsi for the chip, describing the
fundamental peripherals: the cores, GIC, timer, RTC, CCU and pinctrl.
Also some other peripherals are fully compatible with previous IP, so
add the USB and MMC nodes as well.
The other peripherals will be added in the future, once we understand
their compatibility and DT requirements.

[PATCH v3 10/15] dt-bindings: arm: sunxi: Add new board names for A523 generation

[Andre Przywara]

The new Allwinner A523 SoC family comes in different packages, though
they all share the same die, and so the devicetree bindings.

Add three board names that use a version from this SoC family:
- The Avaota A1: an Open Source hardware router board.
- The Radxa Cubie A5E: a typical development board
- The X96QPro+: a TV box

Add their compatible name to the list.

[PATCH v3 11/15] arm64: dts: allwinner: a523: add Avaota-A1 router support

[Andre Przywara]

The Avaota A1 router board is an Open Source hardware board, designed
by YuzukiHD. Pine64 produces some boards and sells them. It uses the
Allwinner A527 or T527 SoC, and comes with the following features:
  - Eight ARM Cortex-A55 cores, Mali-G57 MC1 GPU
  - 1GiB/2GiB/4GiB LPDDR4 DRAM
  - AXP717 + AXP323 PMIC
  - Raspberry-Pi-2 compatible GPIO header
  - 1 USB 2.0 type A host port, 1 USB 3.0 type A host post
  - 1 USB 2.0 type C port (OTG + serial debug)
  - MicroSD slot
  - eMMC between 16 and 128 GiB
  - on-board 16MiB bootable SPI NOR flash
  - two 1Gbps Ethernet ports (via RTL8211F PHYs)
  - HDMI port
  - DP port
  - camera and LCD connectors
  - 3.5mm headphone jack
  - (yet) unsupported WiFi/BT chip
  - 1.3" LC display, connected via SPI
  - 12 V barrel plug for power supply

Add the devicetree file describing the currently supported features.

[PATCH v3 12/15] arm64: dts: allwinner: a523: add X96Q-Pro+ support

[Andre Przywara]

The X96QPro+ is a TV box using the Allwinner H728 SoC. That SoC seems to
be a package variant of the A523 family, at least it uses the same SoC
ID and is compatible as far as we can assess.

It comes with the following specs:
  - Allwinner H728 SoC: 8 Arm Cortex-A55 cores, Mali-G57 MC1 GPU
  - 2 or 4GiB DDR3L DRAM
  - 32, 64, or 128 GiB eMMC flash
  - AXP717 + AXP323 PMICs
  - Gigabit Ethernet (using MAXIO PHY)
  - HDMI port
  - 2 * USB 2.0 ports
  - 1 * USB 3.0 port
  - microSD card slot
  - TOSLINK digital audio output
  - 3.5mm A/V port
  - infrared sensor
  - 7-segment display
  - 5V barrel plug power supply
  - power button

The PCB provides holes for soldering a UART header or cable, this is
connected to the debug UART0. There is another set of UART pins
available. The board also features a FEL button (accessible through the
3.5mm socket) and a reset button (only accessible when case is open).

This .dts just describes the basic peripherals as far as we support them
at the moment. The PMIC rail assignments are reverse engineered as far
as possible, by dumping them from a running Android system, and correlating
them to other boards using the same SoC.

[PATCH v3 13/15] arm64: dts: allwinner: a523: add Radxa A5E support

[Andre Przywara]

The Radxa A5E is a development board using the Allwinner A527 SoC, which
is using the same die as the A523 SoC, just exposing the pins of more
peripherals (like HDMI or the 2nd MAC). The board features:

  - Allwinner A527/T527 SoC: 8 ARM Cortex-A55 cores, Mali-G57 MC1 GPU
  - 1GiB/2GiB/4GiB LPDDR4 DRAM
  - AXP717 + AXP323 PMICs
  - Raspberry-Pi-2 compatible 40pin GPIO header
  - 1 USB 2.0 type C port (OTG), also power supply
  - 1 USB 3.0 type A host port (multiplexed with M.2 slot)
  - 1 M.2 M-key 2230 slot, with 1 PCIe2.1 lane connected (multiplexed
    with USB 3.0 port)
  - MicroSD slot
  - optional eMMC, 8, 16 or 32GB available
  - optional on-board 16MiB bootable SPI NOR flash
  - two 1Gbps Ethernet ports (via MAXIO MAE0621A PHYs)
  - PoE header for optional supply circuit on one Ethernet port
  - WiFi 802.11 a/b/g/n/ac/ax (LB-Link BL-M8800DS2 module using AIC8800)
  - HDMI port
  - camera and LCD connectors
  - power supply via USB-C connector (but no PD) or GPIO header pins

This .dts describes the devices as far as we support them at the moment.
The PMIC rails have been assigned as per the schematics.

[PATCH v3 15/15] arm64: dts: allwinner: h616: add YuzukiHD Chameleon support

[Andre Przywara]

The Chameleon board is an OpenHardware devboard made by YuzukiTsuru.
The form factor resembles the Raspberry Pi Model A boards, though it
differs significantly in its features:

  - Allwinner H618 SoC (4 * Arm Cortex-A53 cores, 1MB L2 cache, 1.4 GHz)
  - between 512MiB and 2GiB DDR3 DRAM
  - up to 128 GiB eMMC flash
  - AXP313a PMIC
  - 100 Mbit/s Ethernet pins on a header
  - XR829 WIFI+Bluetooth chip
  - 4 * USB 2.0 USB-C ports
  - microSD card slot
  - 3.5mm A/V port

Add the devicetree describing the board's peripherals and their
connections.

[tip: irq/drivers] irqchip/sunxi-nmi: Support Allwinner A523 NMI controller

[tip-bot2 for Andre Przywara]

irqchip/sunxi-nmi: Support Allwinner A523 NMI controller

The NMI controller in the Allwinner A523 is almost compatible to the
previous versions of this IP, but requires the extra bit 31 to be set in
the enable register to actually report the NMI.

Add a mask to allow such an enable bit to be specified, and add this to
the per-SoC data structure. As this struct was just for different register
offsets so far, it was consequently named "reg_offs", which is now no
longer applicable, so rename this to the more generic "data" on the way,
and move the existing offsets into a struct of its own.

Also add the respective Allwinner A523 compatible string, and set bit 31
in its enable mask, to add support for this SoC.

[ tglx: Mop up some coding style along with it ]

dt-bindings: irq: sun7i-nmi: Document the Allwinner A523 NMI controller

The Allwinner A523 SoC contains an NMI controller very close to the one
used in the recent Allwinner SoCs, but it adds another bit that needs to
be toggled to actually deliver the IRQs. Sigh.

Add the A523 specific name to the list of allowed compatible strings.

is there any chance that this DT binding patch (and patch 04/15, touching
the actual driver) would make it into -next any time soon, and hopefully
into v6.15? From what I can see it's the only binding left before the
sunxi maintainers can merge the devicetree patches for this new SoC (most
others are in, pinctrl and NMI should show up in the next days).

Let me know if I can help with anything or if you need more information!

Thanks,
Andre
