[PATCH 0/8] Add CAMSS and IMX577 sensor support for Shikra EVK

[PATCH 0/8] Add CAMSS and IMX577 sensor support for Shikra EVK

[Nihal Kumar Gupta]

Shikra EVK is based on the Qualcomm Shikra SoC.
It lacks a camera sensor in its default configuration.
This series adds CAMSS driver support, CCI definitions and enables
the 22-pin IMX577 sensor via CSIPHY0 through a device tree overlay.

We have tested IMX577 Sensor on CCI1 with following commands:
- media-ctl --reset
- media-ctl -d /dev/media0 -V '"imx577 1-001a":0[fmt:SRGGB10/4056x3040 field:none]'
- media-ctl -d /dev/media0 -V '"msm_csiphy1":0[fmt:SRGGB10/4056x3040]'
- media-ctl -d /dev/media0 -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]'
- media-ctl -d /dev/media0 -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]'
- media-ctl -d /dev/media0 -l '"msm_csiphy1":1->"msm_csid0":0[1]'
- media-ctl -d /dev/media0 -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
- yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 4056x3040 -F /dev/video0

Used following tools for the sanity check of these changes.

[PATCH 1/8] dt-bindings: media: qcom: Add Shikra CAMSS compatible

[Nihal Kumar Gupta]

Shikra uses the same CAMSS IP as QCM2290. Extend the existing
qcom,qcm2290-camss binding to add the qcom,shikra-camss compatible
string.

If it uses the same binding then why does it need minItems:1 ?

Does Shikra have only the one iommus entry - if so why ?

If not then adding minItems: 1 is nothing to do with adding another
compatible string.

Either way this patch isn't right.

No. Same feedback as before - you need to describe now the items if you
claim that there is distinction. I already pointed this out to Qualcomm
at least two or three times.

ACK, We will simply add fallback to 2290 in dts.

So I'm suspicious of this IOMMU.

We should list the full range of IFE SIDs here not a subset. Since we are
register compatible with Agatti that implies to me we should also be IOMMU
compatible.

Please list in your next submission commit log the IOMMU SIDs - comment in
the DTS is fine too.

Ideally list the IOMMus for Agatti/2290 and then explain why the singleton
you have enumerated here is the only required one.

Right now my suspicion radar is high that either the Agatti binding is
wrong or the Shikra binding is.

Possibly both.

Shikra and Agatti are not iommu compatible in terms of Stream ID. Only VFE SID is same
for both. Agatti is documenting iommu for VFE, CDM and OPE. OPE is not yet enabled for
Shikra and in my opinion it should be added as a separate yaml similar to Agatti.
"https://lore.kernel.org/all/20260508-camss-isp-ope-v3-9-bb1055274603@oss.qualcomm.com/"

Regarding cdm iommu we have excluded it as we do not use it to program registers as of now.

Loic/Bryan, Please share your thoughts on this?

Sure.

Which will be a problem as soon as CDM is attempted to be enabled and 
yaml changes are dropped upstream.

Hmm then it seems to me that five is too many for Agatti's IOMMU set.

I'd like a number list so that we are discussing facts instead of 
nebulous hypotheticals.

For both Agatti and Shikra.

[PATCH 7/8] arm64: dts: qcom: shikra-cqm-evk-imx577-camera: Add DT overlay

[Nihal Kumar Gupta]

Shikra CQM and CQS are retail variants sharing the same PM4125 PMIC
and identical camera supply rails. The only difference between them
is the integrated modem on CQM, which does not affect camera hardware.

Add a shared overlay for optional IMX577 integration via CSIPHY1,
used by both CQM and CQS EVK boards.

If the overlay is not specific to board then the overlay should have some
kind of base name shikra-evk-imx577-camera.dtb

This seems like a minor nit-pick and, it is :)

Thanks for the review!

The overlay is named after CQM because it's shared between CQM and CQS
both use PM4125 PMIC with identical camera supply rails. The only
difference between them is the integrated modem on CQM, which does not
affect camera hardware at all.

IQS uses PM8150 with different supply rails, so it needs its own overlay
and can't share with CQM/CQS. A generic shikra-evk-imx577-camera name 
would be misleading since IQS is not compatible with this overlay. 

Happy to rename to shikra-cqm-cqs-evk-imx577-camera if that makes the
shared scope clearer - open to suggestions.

That would sufficiently pick the nit for me.

[PATCH 8/8] arm64: dts: qcom: shikra-iqs-evk-imx577-camera: Add DT overlay

[Nihal Kumar Gupta]

Shikra IQS is an industrial-grade variant using PM8150 PMIC, requiring
different CSIPHY and sensor supply rails compared to the retail boards
(CQM and CQS) which use PM4125.

Add a dedicated overlay for optional IMX577 integration via CSIPHY1.

I don't have your schematic BUT where are the rest of the regulators.

If they are absent or powered by the daughter board, a comment in the patch
would be warranted.

Same comment for previous patch.

/*
 * avdd and dvdd are supplied by on-board regulators on the IMX577
 * module from the connector's 3.3 V rail; they are not SoC-controlled.
 * dovdd is the only supply sourced from the SoC PMIC.

Sure, I'll add this comment in v2.
