| * Freescale CMOS Sensor Interface (CSI) V4L2 Capture |
| |
| Required properties for CSI |
| - compatible: "fsl,<soc>-csi". Supported chip includes imx6sl |
| - reg: Address and length of the register set for CSI |
| - interrupts: Should contain CSI interrupts |
| |
| Required properties for v4l2_capture |
| - compatible: should be "fsl,<soc>-csi-v4l2", supported socs include imx6sl |
| |
| Required properties for sensor |
| - compatible: "<vendor>,<sensor>" |
| please check the supported sensor in the Supported Sensor fields. |
| - reg: sensor I2C slave address |
| - pinctrl-names: should be "default" for parallel sensor |
| - pinctrl-0: should depend on the connection between sensor and i.MX |
| connection between sensor and i.MX could be only legacy parallel on i.MX6SL |
| - clocks: should be the clock source provided to sensor. |
| - clock-names: should be "csi_mclk" |
| - AVDD-supply: set according to the board. |
| - DVDD-supply: set according to the board. |
| - pwn-gpios: set according to the board. |
| - rst-gpios: set according to the board. |
| - csi_id: csi id for v4l2 capture device |
| should be 0 for i.MX6SL |
| - mclk: should the value of mclk clock send out the sensor. unit is Hz. |
| - mclk_source: should be 0 for i.MX6SL |
| |
| Supported Sensor |
| - ovti, ov5640 |
| |
| Example for CSI: |
| csi: csi@020e4000 { |
| compatible = "fsl,imx6sl-csi"; |
| reg = <0x020e4000 0x4000>; |
| interrupts = <0 7 0x04>; |
| status = "disabled"; |
| }; |
| |
| Examples for v4l2_capture: |
| csi_v4l2_cap { |
| compatible = "fsl,imx6q-v4l2-capture"; |
| status = "okay"; |
| }; |
| |
| Examples for sensors: |
| ov564x: ov564x@3c { |
| compatible = "ovti,ov564x"; |
| reg = <0x3c>; |
| pinctrl-names = "default"; |
| pinctrl-0 = <&pinctrl_csi_0>; |
| clocks = <&clks IMX6SL_CLK_CSI>; |
| clock-names = "csi_mclk"; |
| AVDD-supply = <&vgen6_reg>; /* 2.8v */ |
| DVDD-supply = <&vgen2_reg>; /* 1.5v*/ |
| pwn-gpios = <&gpio1 25 1>; |
| rst-gpios = <&gpio1 26 0>; |
| csi_id = <0>; |
| mclk = <24000000>; |
| mclk_source = <0>; |
| }; |
