[PATCH v7 1/5] dt-bindings: clock: qcom,sdm845-camcc: add sdm670 compatible

[Richard Acayan]

The camera clocks on SDM670 and SDM845 have no significant differences
that would require a change in the clock controller driver. The only
difference is the clock frequency at each level of the power domains,
which is not specified in the clock driver. There should still be a
compatible specific to the SoC, so add the compatible for SDM670 with
the SDM845 compatible as fallback.

[PATCH v7 2/5] dt-bindings: media: camss: Add qcom,sdm670-camss

[Richard Acayan]

As found in the Pixel 3a, the Snapdragon 670 has a camera subsystem with
3 CSIDs and 3 VFEs (including 1 VFE lite). Add this camera subsystem to
the bindings.

Adapted from SC8280XP camera subsystem.

Hi Richard.

Thanks for sticking with the series.

Could you please implement this yaml as per the latest format here:

https://lore.kernel.org/linux-arm-msm/20241206191900.2545069-2-quic_vikramsa@quicinc.com

- Ordering of the description of the nodes should follow
   the example and the example should be in-line with:
   Documentation/devicetree/bindings/dts-coding-style.rst

- Sort regs, clocks, interrupts alphanumerically

Please move these regulators into the CSIPHY declaration.

I think you sorted the regs, interrupts but forgot the clocks ?

Do you mean the first three clocks placed first? The order was suggested
by Vladimir in [1], but I can undo it.

We've had a long, long discussion on ordering subsequent.

Have a look at the sc7280 and align your ordering with that.

Ok, it seems SC7280 renames the CSID clocks to change their alphabetical
sorting so I'll rename them as well.

	csi0 -> vfe0_csid
	csi1 -> vfe1_csid
	csi2 -> vfe_lite_csid

Let's not do this, the "csiX" clock names are also used in camss-csid.c
and would need deeper driver changes.
