[PATCH v7 0/5] Add CCI and imx577 sensor support for monaco evk

[PATCH v7 0/5] Add CCI and imx577 sensor support for monaco evk

[Nihal Kumar Gupta]

From: nihalkum <nihalkum@qti.qualcomm.com>

Monaco EVK is a single-board computer based on the Qualcomm QCS8300 SoC.
It lacks a camera sensor in its default configuration.
This series adds CCI support and enables the IMX577 sensor via CSIPHY1
through device tree overlay.

We have tested IMX577 Sensor on CCI1 with following commands:
- media-ctl --reset
- media-ctl -V '"imx577 3-001a":0[fmt:SRGGB10/4056x3040 field:none]'
- media-ctl -V '"msm_csiphy1":0[fmt:SRGGB10/4056x3040]'
- media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]'
- media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]'
- media-ctl -l '"msm_csiphy1":1->"msm_csid0":0[1]'
- media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
- yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 4056x3040 -F /dev/video1

[PATCH v7 1/5] dt-bindings: i2c: qcom-cci: Document qcs8300 compatible

[Nihal Kumar Gupta]

The three instances of CCI found on the QCS8300 are functionally the same
as on a number of existing Qualcomm SoCs.

Introduce a new SoC-specific compatible string "qcom,qcs8300-cci" with a
common fallback.

[PATCH v7 2/5] arm64: dts: qcom: monaco: Add CCI definitions

[Nihal Kumar Gupta]

Qualcomm QCS8300 SoC contains three Camera Control Interface (CCI).
Compared to Lemans, the key difference is in SDA/SCL GPIO assignments
and number of CCIs.

[PATCH v7 5/5] arm64: dts: qcom: monaco-evk-camera: Add DT overlay

[Nihal Kumar Gupta]

Monaco EVK board does not include a camera sensor in its default hardware
configuration. Introducing a device tree overlay to support optional
integration of the IMX577 sensor via CSIPHY1.

Camera reset is handled through an I2C expander, and power is enabled
via TLMM GPIO74.

An example media-ctl pipeline for the imx577 is:

media-ctl --reset
media-ctl -V '"imx577 3-001a":0[fmt:SRGGB10/4056x3040 field:none]'
media-ctl -V '"msm_csiphy1":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]'
media-ctl -l '"msm_csiphy1":1->"msm_csid0":0[1]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 4056x3040 -F /dev/video1

data-lanes property value should be '1 2 3 4>', 0 is for the clock lane.

On CAMSS side this cannot be changed, unfortunately it's a lingering issue.

If only one of 3 defined from 4/5 regulators is used, do you really wish
to describle all 3 in advance? You may consider to remove 2 currently unused
GPIO controlled regulator descriptions, and squash this change with 4/5.

So, I should set data-lanes = <1 2 3 4> in imx577_ep1, and keep csiphy1_ep as <0 1 2 3>, correct?
Is there a reason CAMSS side can’t change this? We should handle it properly in future targets.

As discussed, we agreed to add support for other sensors: https://lore.kernel.org/all/4b73f64a-1e28-4f25-80d2-3d59575b9da2@oss.qualcomm.com

Regulator changes are in monaco-evk.dts, and sensor overlay changes are present in monaco-evk-camera-imx577.dtso
It’s better to keep these as separate patches rather than merging them into one.

This is useful, if only to surely park them when unused.
