[PATCH 1/6] thermal/drivers/sun8i: add gpadc clock

[iuncuim]

From: Mikhail Kalashnikov <iuncuim@gmail.com>

Some processors (e.g. Allwinner A523) require GPADC clocking activation for
temperature sensors to work. So let's add support for enabling it.

Why calling clk_prepare_enable() ? devm_clk_get_enabled() did the job no ?

[PATCH 2/6] thermal/drivers/sun8i: replace devm_reset_control_get to shared

[iuncuim]

From: Mikhail Kalashnikov <iuncuim@gmail.com>

The A523 processor has two temperature controllers, but they share a common
reset line. We need to use devm_reset_control_get_shared() instead of
devm_reset_control_get()

You could just use devm_reset_control_get_shared_deasserted() and then
drop the reset_control_deassert() and devm_add_action_or_reset() stuff below
this hunk. This simplifies the driver a bit.

[PATCH 3/6] thermal/drivers/sun8i: Add support for A523 THS0/1 controllers

[iuncuim]

From: Mikhail Kalashnikov <iuncuim@gmail.com>

The A523 processor has two temperature controllers, THS0 and THS1.
THS0 has only one temperature sensor, which is located in the DRAM.

THS1 does have 3 sensors:
ths1_0 - "big" cores
ths1_1 - "little" cores
ths1_2 - gpu

The datasheet mentions a fourth sensor in the NPU, but lacks any registers
for operation other than calibration registers. The vendor code reads the
value from ths1_2, but uses separate calibration data, so we get two
different values from real one.

[PATCH 4/6] arm64: dts: allwinner: A523: Add SID controller node

[iuncuim]

From: Mikhail Kalashnikov <iuncuim@gmail.com>

The SID controller should be compatible with A64 and others SoC with 0x200
offset.

But this also needs a matching update to the binding.

[PATCH 5/6] arm64: dts: allwinner: A523: Add thermal sensors and zones

[iuncuim]

From: Mikhail Kalashnikov <iuncuim@gmail.com>

The A523 processor has two temperature controllers, THS0 and THS1.
THS0 has only one temperature sensor, which is located in the DRAM.

THS1 does have 3 sensors:
ths1_0 - "big" cores
ths1_1 - "little" cores
ths1_2 - gpu

Add the thermal sensor configuration and the thermal zones

Including unrelated bits is probably not correct. Instead I think it should
be two cells. The thermal driver then has to stitch them together or something.

We could have passive trip points here as well so thermal throttling of
the GPU could work.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/thermal/allwinner,sun8i-a83t-ths.example.dtb: thermal-sensor@1c25000 (allwinner,sun8i-h3-ths): clock-names:1: 'gpadc' was expected
	from schema $id: http://devicetree.org/schemas/thermal/allwinner,sun8i-a83t-ths.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250411003827.782544-7-iuncuim@gmail.com

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.

Thanks for the reply, I didn't know about this tool, I will use it in v2.

Yes, I forgot to point out that the patches are based on 6.15-rc1 using dts
patches from that series that didn't make it into the latest rc:
https://lore.kernel.org/linux-sunxi/20250307005712.16828-1-andre.przywara@arm.com/T/#t
I'll add that information to the cover letter.

That's obvious from the diff. What's not is how is the h/w different 
from prior versions? For example, why is there another clock?

You cannot add new entries in the middle. They must go on the end and 
you then need to restrict the existing users to 2 clocks. And for the 
new users, how many clocks are required? 1, 2, or 3?

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/next-20250411 (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

Chen-Yu merged those patches already, to the sunxi repo on kernel.org,
under the dt-for-6.16 branch, so you can reference that instead, and
also base any new patches on that.
