With the CSI and mipi_csi2 drivers pointing to an OV5640 camera, the media pipeline can be configured with the following: media-ctl --links "'ov5640 1-003c':0->'imx7-mipi-csis.0':0[1]" The camera and various nodes in the pipeline can be configured for UYVY: media-ctl -v -V "'ov5640 1-003c':0 [fmt:UYVY8_1X16/640x480 field:none]" media-ctl -v -V "'csi':0 [fmt:UYVY8_1X16/640x480 field:none]" Signed-off-by: Adam Ford Reviewed-by: Fabio Estevam Signed-off-by: Shawn Guo --- diff --git a/arch/arm64/boot/dts/freescale/imx8mm-beacon-baseboard.dtsi b/arch/arm64/boot/dts/freescale/imx8mm-beacon-baseboard.dtsi index 4097a66163b2a..0da311898e01e 100644 --- a/arch/arm64/boot/dts/freescale/imx8mm-beacon-baseboard.dtsi +++ b/arch/arm64/boot/dts/freescale/imx8mm-beacon-baseboard.dtsi @@ -54,6 +54,16 @@ enable-active-high; }; + reg_camera: regulator-camera { + compatible = "regulator-fixed"; + regulator-name = "mipi_pwr"; + regulator-min-microvolt = <2800000>; + regulator-max-microvolt = <2800000>; + gpio = <&pca6416_1 0 GPIO_ACTIVE_HIGH>; + enable-active-high; + startup-delay-us = <100000>; + }; + reg_usdhc2_vmmc: regulator-usdhc2 { compatible = "regulator-fixed"; regulator-name = "VSD_3V3"; @@ -78,6 +88,10 @@ }; }; +&csi { + status = "okay"; +}; + &ecspi2 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_espi2>; @@ -101,6 +115,30 @@ pinctrl-names = "default"; pinctrl-0 = <&pinctrl_i2c2>; status = "okay"; + + camera@3c { + compatible = "ovti,ov5640"; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_ov5640>; + reg = <0x3c>; + clocks = <&clk IMX8MM_CLK_CLKO1>; + clock-names = "xclk"; + assigned-clocks = <&clk IMX8MM_CLK_CLKO1>; + assigned-clock-parents = <&clk IMX8MM_CLK_24M>; + assigned-clock-rates = <24000000>; + AVDD-supply = <®_camera>; /* 2.8v */ + powerdown-gpios = <&gpio1 7 GPIO_ACTIVE_HIGH>; + reset-gpios = <&gpio1 6 GPIO_ACTIVE_LOW>; + + port { + /* MIPI CSI-2 bus endpoint */ + ov5640_to_mipi_csi2: endpoint { + remote-endpoint = <&imx8mm_mipi_csi_in>; + clock-lanes = <0>; + data-lanes = <1 2>; + }; + }; + }; }; &i2c4 { @@ -152,6 +190,18 @@ }; }; +&mipi_csi { + status = "okay"; + ports { + port@0 { + imx8mm_mipi_csi_in: endpoint { + remote-endpoint = <&ov5640_to_mipi_csi2>; + data-lanes = <1 2>; + }; + }; + }; +}; + &sai3 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_sai3>; @@ -238,6 +288,14 @@ >; }; + pinctrl_ov5640: ov5640grp { + fsl,pins = < + MX8MM_IOMUXC_GPIO1_IO07_GPIO1_IO7 0x19 + MX8MM_IOMUXC_GPIO1_IO06_GPIO1_IO6 0x19 + MX8MM_IOMUXC_GPIO1_IO14_CCMSRCGPCMIX_CLKO1 0x59 + >; + }; + pinctrl_pcal6414: pcal6414-gpiogrp { fsl,pins = < MX8MM_IOMUXC_SAI2_MCLK_GPIO4_IO27 0x19
