Device tree configuration[edit | edit source]
Here below an example of device tree configuration used on standard DAVE's kit for the AXELLite SOM:
From imx6qdl-sbcx-revb-common.dtsi:
&mipi_csi {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_mipi_csi_axel_sbc>;
status = "okay";
ipu_id = <0>;
csi_id = <1>;
v_channel = <0>;
lanes = <2>;
};
From imx6qdl-axelcommon.dtsi:
&iomuxc {
...
...
pinctrl_mipi_csi_axel_sbc: mipi_csigrp-2 {
fsl,pins = <
MX6QDL_PAD_SD3_DAT7__GPIO6_IO17 0x0b0b0 /* ov5640 mipi powerdown */
MX6QDL_PAD_SD3_DAT6__GPIO6_IO18 0x000b0 /* ov5640 mipi reset */
MX6QDL_PAD_CSI0_MCLK__CCM_CLKO1 0x000b0 /* ov5640 mclk */
