[PATCH v3 0/6] 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 CSIPHY1 through device tree overlays.

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.
- make -j32 W=1
- checkpatch.pl
- make DT_CHECKER_FLAGS=-m W=1 DT_SCHEMA_FILES=i2c/qcom,i2c-cci.yaml dt_binding_check
- make DT_CHECKER_FLAGS=-m DT_SCHEMA_FILES=media/qcom,qcm2290-camss.yaml dt_binding_check W=1
- make CHECK_DTBS=y W=1 qcom/qrb2210-rb1-vision-mezzanine.dtb
- make CHECK_DTBS=1 W=1 qcom/shikra-cqm-cqs-evk-imx577-camera.dtb
- make CHECK_DTBS=1 W=1 qcom/shikra-iqs-evk-imx577-camera.dtb
- make CHECK_DTBS=y W=1 dtbs

The Shikra CAMSS binding patch does not depend on the rest of the series
and can go through the media tree on its own.

This patch series depends on patch series:

Changes in v3:
- Drop dt-bindings: i2c: qcom-cci: Document Shikra compatible; already
  picked by Andi Shyti into her i2c tree (now in linux-next as e3a8f8329397)
- Preserve blank line after compatible const in qcom,qcm2290-camss.yaml (Krzysztof)
- Add blank line between iommus and power-domains in CAMSS node (Vladimir)
- Fix data-lanes numbering to start from 1 in all endpoints (Vladimir)
- Move cam1_reset_default pinctrl state from board .dts files into the
  mezzanine .dtso overlay files (Vladimir)
- Collect Reviewed-by tags
- Link to v2: https://lore.kernel.org/r/20260608-shikra-camss-review-v2-0-ca1936bf1219@oss.qualcomm.com

Changes in v2:
- Drop qcm2390_resources struct and CAMSS_2390 enum; use qcom,qcm2290-camss
  as fallback compatible string since Shikra CAMSS is register-compatible
  with QCM2290 (Loic, Bryan)
- Use oneOf in iommus to describe all valid SID combinations: VFE-only
  (Shikra) and VFE+CDM+OPE read+OPE write (QCM2290/Agatti); add
  per-entry descriptions naming each SID (Krzysztof, Bryan)
- Rename shikra-cqm-evk-imx577-camera overlay to
  shikra-cqm-cqs-evk-imx577-camera, shared by both CQM and CQS EVK
  boards which use the same PM4125 PMIC and camera supply rails (Bryan)
- Add reset-gpios pinctrl state for IMX577 sensor (gpio33, cam1-reset-default-state)
- Add comment in overlay DTS explaining absent regulators are powered
  by the daughter board (Bryan)
- Collect Reviewed-by tags
- Add reset-gpios pinctrl state for IMX577 sensor.
