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 Signed-off-by: Nihal Kumar Gupta <redacted> 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: Vikram Sharma <redacted> Reviewed-by: Vladimir Zapolskiy <vladimir.zapolskiy@linaro.org> Reviewed-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org> --- arch/arm64/boot/dts/qcom/Makefile | 4 + .../dts/qcom/monaco-evk-camera-imx577.dtso | 105 ++++++++++++++++++ 2 files changed, 109 insertions(+) create mode 100644 arch/arm64/boot/dts/qcom/monaco-evk-camera-imx577.dtso
