[PATCH 0/5] Add interconnects to QUPs on SM8250

[PATCH 0/5] Add interconnects to QUPs on SM8250

[Konrad Dybcio]

SM8250 (like SM8150 but unlike all other QUP-equipped SoCs) doesn't
provide a qup-core path. Adjust the bindings and drivers as necessary,
and then describe the icc paths in the device tree. This makes it possible
for interconnect sync_state succeed so long as you don't use UFS.

Some SoCs (like SM8150 and SM8250) don't seem to provide a qup-core path.
Allow such case.

[PATCH 4/5] soc: qcom: geni-se: Allow any combination of icc paths

[Konrad Dybcio]

Not all SoCs provide all the usual paths. By the looks of it, at least
SM8150 and SM8250 don't have one that would resemble "qup-core".

Check for the error that icc_get throws and assign a NULL value to each
path that can't be found to effectively allow any combination of icc paths
(which, like previously, includes no icc paths). The ICC APIs gracefully
handle a NULL path by exiting early.

[PATCH 5/5] arm64: dts: qcom: sm8250: Add interconnects and power-domains to QUPs

[Konrad Dybcio]

Describe the interconnect paths related to QUPs and add the power-domains
powering them.

This is required for icc sync_state, as otherwise QUP access is gated.

Instead please keep the definition of the fields in top-level properties
with the widest constraints, e.g.
interconnects:
  minItems: 1
  maxItems: 2

interconnect-names:
  minItems: 1
  items:
   - const: qup-core
   - const: qup-config

If there was allOf:if:then per variant, this could be further customized.

Would it make sense to add (devm_)of_icc_get_optional instead?  I think 
we already have several usecases for such API call

Sadly the issue here is that the qup-config path exists, but qup-core
doesn't.

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.

If you already ran 'make dt_binding_check' and didn't see the above

that DT_SCHEMA_FILES can be set to your schema file to speed up checking

The "qup-core" path is a vote between two nodes on the QUP0 BCM, to
provide a frequency vote on the QUP core(s). Both SM8150 and SM8250 has
this BCM, but as you point out it's not exposed through the interconnect
provider.

I don't know why this is, but I think it would be preferable to amend
the provider.

Un-reviewed. Don't define properties in oneOf, instead use the syntax I
pointed out in other patch. If you remove interconnects from this
example, you will reproduce the error.

This should be something like:
          interconnects:


            minItems: 2
            maxItems: 3

          interconnect-names:
            oneOf:
              - items:
                  - const: qup-config
                  - const: qup-memory

              - items:
                  - const: qup-core
                  - const: qup-config
                  - const: qup-memory
