[PATCH 0/3] riscv: allwinner: ClockworkPi and DevTerm devicetrees

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

Hi folks,

Here are a couple patches that were originally sent by Samuel, but later
dropped due to the system LDO regulator bindings not getting merged. The
regulator bindings were recently resent and landed [1], so now is the time
to get the rest of the stragglers in.

Patch 1 and 3 were originally part of Samuel's D1 device tree submission [2].

Patch 2 was part of the system LDO series [3].

These have been rebased onto v6.10-rc1 and have been compile tested
only.

I plan to land these in the coming week for 6.11.


Regards
ChenYu

[PATCH 1/3] dt-bindings: sram: sunxi-sram: Add regulators child

[Chen-Yu Tsai]

From: Samuel Holland <samuel@sholland.org>

Some sunxi SoCs have in-package regulators controlled by a register in
the system control MMIO block. Allow a child node for this regulator
device in addition to SRAM child nodes.

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

I'm not seeing this error locally. The binding in question for
'allwinner,sun20i-d1-system-ldos' was merged in v6.10-rc1 in commit
622bab188484 ("regulator: dt-bindings: Add Allwinner D1 system LDOs").

I only tried on top of linux-next from a few days ago, but it didn't
reproduce for me there. I think you're okay.

[PATCH 2/3] riscv: dts: allwinner: d1s-t113: Add system LDOs

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

Now that the bindings for the system LDOs have been merged, the nodes
for the system LDOs can be added. These are used on the ClockworkPi.

This was originally part of Samuel's D1 device tree series [1], but was
dropped in v5 as the regulator bindings weren't merged at the time.

[PATCH 3/3] riscv: dts: allwinner: Add ClockworkPi and DevTerm devicetrees

[Chen-Yu Tsai]

From: Samuel Holland <samuel@sholland.org>

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.
