Hi,
I am trying to clock my OV5640 through the MIPI_CSI0_MCLK_OUT pin. With the configuration below, there is no clock signal on this pin. Any idea why? Do I need to use a different clock source coming from the ACM module?
DT for Camera:
/* MIPI-CSI0 I2C available on MIPI Camera connector */
&i2c_mipi_csi0 {
#address-cells = <1>;
#size-cells = <0>;
pinctrl-names = "default", "gpio";
pinctrl-0 = <&pinctrl_csi0_lpi2c0>;
pinctrl-1 = <&pinctrl_csi0_lpi2c0_gpio>;
scl-gpios = <&lsio_gpio3 5 GPIO_ACTIVE_HIGH>;
sda-gpios = <&lsio_gpio3 6 GPIO_ACTIVE_HIGH>;
clock-frequency = <100000>;
status = "disabled";
/* MIPI-CSI2 camera */
ov5640_mipi: ov5640_mipi@3c {
compatible = "ovti,ov5640";
reg = <0x3c>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_mipi>;
clocks = <&xtal24m>;
clock-names = "xclk";
csi_id = <0>;
reset-gpios = <&lsio_gpio3 3 GPIO_ACTIVE_LOW>;
powerdown-gpios = <&lsio_gpio3 2 GPIO_ACTIVE_HIGH>;
mclk = <24000000>;
mclk_source = <0>;
mipi_csi;
status = "disabled";
port {
ov5640_mipi_ep: endpoint {
remote-endpoint = <&mipi_csi0_ep>;
data-lanes = <1 2>;
clocks-lanes = <0>;
};
};
};
};
DT for the clock (from freescale/imx8qxp)
xtal24m: clock-xtal24m {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <24000000>;
clock-output-names = "xtal_24MHz";
};
Mipi pinctrl:
pinctrl_mipi: mipi {
fsl,pins = <
IMX8QXP_CSI_RESET_LSIO_GPIO3_IO03 0xC0000041
IMX8QXP_CSI_EN_LSIO_GPIO3_IO02 0xC0000041
IMX8QXP_MIPI_CSI0_MCLK_OUT_MIPI_CSI0_ACM_MCLK_OUT 0xc0000041
>;
};
Thanks!
