Subject: [PATCH v2 2/3] dt-bindings: thermal: Convert loongson2 to json-schema

Convert the loongson2 thermal binding to DT schema format using
json-schema.

Signed-off-by: Yinbo Zhu <[email protected]>
---
Change in v2:
1. Add description and type about the "id".
2. Make the filename was based on compatible.

No improvements here. You ignore my comments, so I am going to NAK it.

No improvements here, so let me be specific - you need to really justify
such property or it cannot go to schema.

How other similar nodes are named (in other DTS files)?

pip3 install dtschema --upgrade

Filename must match the compatible, so: loongson,loongson2-thermal.yaml

This is not reason to add properties to DT. DT describes the hardware,
not driver behavior.

Why hardware needs arbitrary, additional addressing number instead of
standard unit address?

I don't get your point, that dts compatible is "loongson,loongson2-thermal", so this driver file name is named
loongson2-thermal that according what you said about "Filename based on compatible."
If what I understand is not what you expect, please tell me how to modify it.

The interrupts of our dts do not specify an interrupt parent,
eg. interrupts = <7 IRQ_TYPE_LEVEL_LOW>
so we need to add an interrupt parent property.

I refer qoriq platform,
tmu@f0000 {
compatible = "fsl,qoriq-tmu";

You mean to modify it like this
- thermal: thermal@1fe01500 {
+ thermal@1fe01500 {

right ?

The loongson2 series soc supports up to four sensors, but the 2K1000 has only one sensor, so the ID must be 0.
For the 2K1000, in order to distinguish the differences between different hardware in the Loongson2 SoC series,
the ID is added to the dts

Since there is more than one interrupt controller in the Loongson2 series soc, that need to specify the interrupt
controller in the dts, that is, the interrupt parent. If different interrupt parents are used in dts, the interrupt
numbers are different.

That's not an explanation at all. All other SoCs have multiple sensors
and we do not have such "id" fields.

You describe now the overall SoC, but this is a schema for a device, not
entire SoC. I still do not see why interrupt-parent is necessary for
this device.

Differences in SoCs is what 'compatible' is for. If 'loongson2' is not a
specific SoC, then your compatible string is not specific enough.

If one SoC only has 1 sensor, then this could be 0. However, you don't
have to do that, but it's another way to distinguish differences.

It is perfectly valid for the 'interrupt-parent' to be in *any* parent
node. So it is never required by any binding.

If other loongson2 platforms are different from the thermal sensor, I will add compatible
"loongson,loongson2-thermal-xxx", please you note.

I don't get your meaning, You mean I can add it in the dts, but I don't need to add it in the binding file, right?

No, this compatible looks wrong then. What is your SoC model number? You
called loongson2 a "series", so that's not appropriate. Compatible
should be specific.

You should not add it to the binding because it is not related to the
device itself.

Must it be strict here? I have a look about other platforms are similar to this one, eg.
examples:
- |
tmu@f0000 {
compatible = "fsl,qoriq-tmu";
the qoriq series soc include ls1046a/ls1043/ls1088a/...

and the compatible was "loongson,loongson2-xxx" is internal rules, we hope that code can as the rules
to upstream.

okay, I got it. I will add this change in v4.
