| * Freescale V4L2 Capture for i.MX6DQ/i.MX6SDL |
| |
| Required board properties for IPUv3 capture: |
| - clocks: should include the clock provided by i.MX6 to sensor |
| - clock-names: sensor clock's name should be "ipux_csiy" |
| x should be 1 or 2 for i.MX6DQ; should be 1 for i.MX6SDL |
| y is 0 or 1 for i.MX6DQ/i.MX6SDL |
| Note: other detailed information for IPUv3, please refer to |
| Documentation/devicetree/bindings/fb/fsl_ipuv3_fb.txt |
| |
| Required properties for v4l2_capture |
| - compatible: should be "fsl,imx6q-v4l2-capture" |
| - ipu_id: ipu id for v4l2 capture device |
| should be 0 or 1 for i.MX6DQ; should be 0 for i.MX6SDL |
| - csi_id: csi id for v4l2 capture device |
| should be 0 or 1 for i.MX6DQ/i.MX6SDL |
| - mclk_source: should be 0 or 1. two mclk sources at most now |
| - status: should be set to "okay" to enable this device |
| |
| 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 MIPI-CSI2 or legacy parallel |
| - clocks: should be the clock source provided to sensor. |
| - clock-names: should be "csi_mclk" |
| - DOVDD-supply: set according to the board. |
| - 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 or 1 for i.MX6DQ/i.MX6SDL. |
| - mclk: should the value of mclk clock send out the sensor. unit is Hz. |
| - mclk_source: should be 0 or 1 and should be the same as the setting in |
| v4l2_capture. |
| - cvbs: 1 for CVBS input, 0 YPbPr input. This property is only needed for |
| adv7180 tv decoder. |
