[PATCH 0/3] Add CCI and CAMSS support for Kaanapali

[PATCH 0/3] Add CCI and CAMSS support for Kaanapali

[Hangxiang Ma]

This series adds CCI and CAMSS support for Qualcomm Kaanapali SoC.

This series has been tested using the following commands with a downstream
driver for S5KJN5 sensor.
- media-ctl --reset
- media-ctl -V '"msm_csiphy2":0[fmt:SGBRG10/4096x3072]'
- media-ctl -V '"msm_csid0":0[fmt:SGBRG10/4096x3072]'
- media-ctl -V '"msm_vfe0_rdi0":0[fmt:SGBRG10/4096x3072]'
- media-ctl -l '"msm_csiphy2":1->"msm_csid0":0[1]'
- media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
- yavta  --capture=20 -I -n 5 -f SGBRG10P -s 4096x3072 -F  /dev/video0

Driver and dt-binding are waiting to be merged:

arm64: dts: qcom: kaanapali: Add camss node

This commit adds the camss device tree node for the Kaanapali camera
subsystem, defining its registers, clocks, interrupts, interconnects,
and power domains.

Is there a corresponding YAML device tree binding patch for this new
compatible string?

Without the binding schema for qcom,kaanapali-camss, dt_binding_check
cannot validate the hardware description. Should the schema be included
in this patch series to ensure the node properties can be verified?

arm64: dts: qcom: kaanapali: Add camera MCLK pinctrl

This commit defines pinctrl definitions to enable camera master clocks on the

Should there also be corresponding sleep states defined for these MCLK pins?

Typically on Qualcomm platforms, camera sensor drivers request both default
and sleep states. The sleep state safely parks the pad, usually via
bias-pull-down, when the camera is powered off.

Without a sleep state, the MCLK pins might be left floating when powered off
due to the bias-disable setting here, which could cause power leakage. Other
camera pins in the Kaanapali device tree seem to follow the pattern of having
sleep states defined.

Sorry Bjorn, the camss binding + driver series wasn't merged as 
expected, which would cause dt-binding checker failure. Could you please 
revert this series? Bryan expect us to rebase on his new re-arch camss 
and the binding/dtsi may be changed accordingly. Thanks a lot.

Best regards,
Hangxiang

Thank you, I missed this in my dtbs_check. I have backed these changes
