[PATCH v2 0/4] ARM: dts: sunxi: Add MangoPi MQ-R board support

[Andre Przywara]

Hi,

this is v2, mostly acknowledging the fact that there is an Allwinner D1s
version of the board as well, thus splitting the board .dts into a
shared .dtsi and a stub .dts for the ARM version. I don't have the RISC-V
version, so cannot provide (nor test) this .dts file, but creation should
be easy, being based on the shared board .dtsi file.
Since the D1/D1s .dts files are now merged, this patch set should compile
cleanly now.

======================================

The MangoPi MQ-R-T113 is a small SBC with the Allwinner T113-s3 SoC.
That is a very close relative to the Allwinner D1/D1s SoCs, but with
Arm Cortex-A7 cores, and 128 MB of SIP co-packaged DDR3 DRAM.

This series introduces the missing T113-s .dtsi, which builds on top of
the D1/D1s .dtsi, but adds the ARM specific peripherals, like the CPU
cores, the arch timer, the GIC and the PMU.
This requires to add a symlink to the RISC-V DT directory in patch 1/4,
to be able to easily reference the base .dtsi from other architecture
directories.
Since there are versions of the MQ-R boards with the Allwinner D1s,
there is shared .dtsi describing the board peripherals, plus a small
stub .dts to tie together all bits for the actual board.

Cheers,
Andre

Changelog v1 ... v2:
- rebase on top of v6.3-rc3 (including now merged D1/D1s .dtsi files)
- refine board naming, stating both RISC-V and ARM versions
- move board .dts into a shared .dtsi (to cover RISC-V version)
- fix 5V regulator node name

[PATCH v2 1/4] dts: add riscv include prefix link

[Andre Przywara]

The Allwinner D1/D1s SoCs (with a RISC-V core) use an (almost?) identical
die as their R528/T113-s siblings with ARM Cortex-A7 cores.

To allow sharing the basic SoC .dtsi files across those two
architectures as well, introduce a symlink to the RISC-V DT directory.

[PATCH v2 2/4] ARM: dts: sunxi: add Allwinner T113-s SoC .dtsi

[Andre Przywara]

The Allwinner T113-s SoC is apparently using the same (or at least a very
similar) die as the D1/D1s, but replaces the single RISC-V core with
two Arm Cortex-A7 cores.
Since the D1 core .dtsi already describes all common peripherals, we
just need a DT describing the ARM specific peripherals: the CPU cores,
the Generic Timer, the GIC and the PMU.
We include the core .dtsi directly from the riscv DT directory.

[PATCH v2 3/4] dt-bindings: arm: sunxi: document MangoPi MQ-R board names

[Andre Przywara]

The MangoPi MQ-R board is a small development board, using Allwinner
SoCs with co-packaged DRAM. There are versions with a RISC-V core and
ones with two Arm Cortex-A7 cores.

Add the board/SoC compatible string pair to the list of known boards.

[PATCH v2 4/4] ARM: dts: sunxi: add MangoPi MQ-R-T113 board

[Andre Przywara]

The MangoPi MQ-R-T113 is a small SBC with the Allwinner T113-s3 SoC.
The SoC features two Arm Cortex-A7 cores and 128 MB of co-packaged DDR3
DRAM. The board adds mostly connectors and the required regulators, plus
a Realtek RTL8189FTV WiFi chip.
Power comes in via a USB-C connector wired as a peripheral, and there is
a second USB-C connector usable as a host port.

Add a .dtsi file describing most of the board's peripherals, and include
that from the actual board .dts file. This allows to re-use the .dtsi
for the MQ-R-F113 RISC-V variant of that board.

Right, thanks for the heads up. The reason is that the current U-Boot
branch does not enable PSCI services, so the kernel does not know how to
enable and online the second core. As with the other 32-bit parts, the
PSCI nodes and properties get inserted into the DT by U-Boot, at runtime:
arch/arm/lib/psci-dt.c:fdt_psci().

It should be fairly straight-forward to enable that in U-Boot, I will try
to look into this later this week.

Cheers,
Andre
