From: Nihal Kumar Gupta <redacted> 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 Co-developed-by: Ravi Shankar <redacted> Signed-off-by: Ravi Shankar <redacted> Co-developed-by: Vishal Verma <redacted> Signed-off-by: Vishal Verma <redacted> Signed-off-by: Nihal Kumar Gupta <redacted> Signed-off-by: Vikram Sharma <redacted> --- arch/arm64/boot/dts/qcom/Makefile | 4 + .../dts/qcom/monaco-evk-camera-imx577.dtso | 96 +++++++++++++++++++ 2 files changed, 100 insertions(+) create mode 100644 arch/arm64/boot/dts/qcom/monaco-evk-camera-imx577.dtso
