[PATCH 0/2] arm64: dts: qcom: Add Hamoa EVK camera DTSO

[PATCH 0/2] arm64: dts: qcom: Add Hamoa EVK camera DTSO

[Wenmeng Liu]

Hamoa EVK is  based on the Qualcomm X1e80100 SoC.
It lacks a camera sensor in its default configuration.
This series 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

[PATCH 2/2] arm64: dts: qcom: hamoa-iot-evk-camera-imx577: Add DT overlay

[Wenmeng Liu]

Enable IMX577 via CCI on Hamoa EVK Core Kit.

The Hamoa EVK board does not include a camera sensor
by default, this DTSO has enabled the Arducam 12.3MP
IMX577 Mini Camera Module on the CSI-1 interface.

I think this mandates regulator-always-on, as we don't have a 
better solution for that now
