[PATCH 0/3] Add CCI and imx577 sensor support for Talos evk

[PATCH 0/3] Add CCI and imx577 sensor support for Talos evk

[Wenmeng Liu]

Talos EVK is  based on the Qualcomm SM6150 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 -d /dev/media0 --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 -n 5 -f SRGGB10P -s 4056x3040 -F /dev/video0 --capture=5

This patch series depends on patch series:

[PATCH 3/3] arm64: dts: qcom: talos-evk-camera: Add DT overlay

[Wenmeng Liu]

Enable IMX577 via CCI on Taloss EVK Core Kit.

The Talos EVK board does not include a camera sensor
by default, this overlay reflects the possibility of
attaching an optional camera sensor.
For this reason, the camera sensor configuration is
placed in talos-evk-camera.dtso, rather than
modifying the base talos-evk.dts.

Isn't this just camnoc_axi for this device (pay attention: to this device)?

On this SOC, both soc_ahb and camnoc_axi exist.
Is it suggested that I use the existing ones below?
  - if:
       properties:
         compatible:
           contains:
             enum:

--- Isn't this just camnoc_axi for this device (pay attention: to this 
device)?

For this, yes, I think so.
Also tested replacing soc_ahb with camnoc_axi for the CCI device, but 
the hardware did not function correctly with that configuration.

It's common that mezzanine boards are supplied with power from S4A or VBAT,
I've never seen a camera module supplied with just one voltage regulator,
that's why it attracts attention.

What is a camera module here, is it on an attachable vision mezzanine like
on RBx series or a part of Talos EVK PCB like on QRD series?

If it is a mezzanine, the support of mezzanine boards should be done as
a DT overlay.

It`s like RBx series, does not include a camera sensor

Then to add the image sensor support please follow the model with DT overlays,
and it means you shall get a schematics of the mezzanine to describe the
attachable board.

When you get the schematics, you will get a valid view on voltage distribution,
sensor supplies will be derivatives from VBAT or S4A anyway, I believe.

See sm8550-hdk-rear-camera-card.dtso or qrb5165-rb5-vision-mezzanine.dtso as
the references.

Please match the style used in all reasonably non-acient additions:

cci_i2c0_default: cci-i2c0-default-pins {
	/* SDA, SCL */
	pins = "gpio32", "gpio33";
	function = "cci_i2c";
	drive-strength = <2>;
	bias-pull-up;
};

"[...] contains a single controller, containing 2 I2C hosts.
Describe it."
