[PATCH v2 1/9] dt-bindings: arm-smmu: Allow up to 3 power-domains

[Konrad Dybcio]

Some SMMUs require that a vote is held on as much as 3 separate PDs
(hello Qualcomm). Allow it in bindings.

It cannot be 0.

minItems: 1

Anyway you still need to restrict it per variant, as I said in previous
version.

Hm.. I'm not entirely sure what you mean.. Should I add a list of 
compatibles
that are allowed to have 3 power-domains and leave it as it was before 
in the
'else' case?

Yes and limit it to maxItems: 1 for "else".

I tried adding:



   - if:
       properties:
         compatible:
           contains:
             enum:
               - qcom,sm6375-smmu-500
     then:
       properties:
         power-domains:
           minItems: 3
           maxItems: 3
     else:
       properties:
         power-domains:
           maxItems: 1


Right under the nvidia reg if-else in the allOf, but dtbs_check throws 
errors like:


/home/konrad/linux/arch/arm64/boot/dts/qcom/msm8998-sony-xperia-yoshino-poplar.dtb: 
iommu@5040000: 'power-domains' does not match any of the regexes: 
'pinctrl-[0-9]+'


Any clues as to why?

I don't know what code do you have there, but generic pattern is:

It was, but the top-level property said that minItems=3 (implicitly), so
it is too short.

So the top-level properties take precedence over the ones that come from

Right, so it's not a required property. However if it *is* present, then 
it needs to reference at least one power domain, because having an empty 
property, i.e.:

	power-domains = <>;

or
	power-domains;

makes no sense whatsoever.

[PATCH v2 2/9] arm64: dts: qcom: pmk8350: Allow specifying arbitrary SID

[Konrad Dybcio]

PMK8350 is shipped on SID6 with some SoCs, for example with SM6375.
Add some preprocessor logic to allow changing the SID in cases like
this.

While I am not in favour of adding #if's into the device tree, this
is the least messy way to handle this. If one isn't specified, it
will default to 0 (as it has been previously).

[PATCH v2 4/9] arm64: dts: qcom: sm6375: Add pin configs for some QUP configurations

[Konrad Dybcio]

Add the pin setup for SPI/I2C configurations that are supported
downstream. I can guesstimate the correct settings for other buses,
but:

- I have no hardware to test it on
- Some QUPs are straight up missing pin funcs in TLMM
- Vendors probably didn't really care and used whatever was there in
the reference design and BSP - should any other be used, they can be
configured at a later time

[PATCH v2 5/9] arm64: dts: qcom: sm6375: Add QUPs and corresponding SPI/I2C hosts

[Konrad Dybcio]

Add necessary nodes to support various QUP configurations. Note that:

- QUP3/4/5 and 11 are straight up missing
- There may be more QUPs physically on the SoC that work perfectly
fine, but Qualcomm decided not to expose them on the downstream kernel
- Many are missing pinctrls, as there are both missing pin funcs in
the TLMM driver and missing configuration settings (though they are
possible to guesstimate quite easily)

[PATCH v2 9/9] arm64: dts: qcom: sm6375-pdx225: Configure Samsung touchscreen

[Konrad Dybcio]

Add a pretty bog-standard-for-Xperias-for-the-past-3-years
touchscreen setup.

The OEM that built the Xperia 10 IV for SONY decided to use some
kind of a GPIO regulator that needs to be enabled at all times
for both the touch panel and the display panel to function.
