Hi,
I am trying to bring up ov5645 in db820c board. My device tree entries for ov5645 are as follows:
cci@a0c000 {
status = "ok";
camera_board@3c {
compatible = "ovti,ov5645";
reg = <0x3c>;
enable-gpios = <&msmgpio 130 GPIO_ACTIVE_HIGH>;
reset-gpios = <&msmgpio 23 GPIO_ACTIVE_LOW>;
pinctrl-names = "default";
pinctrl-0 = <&camera_primary_default>;
clocks = <&mmcc CAMSS_MCLK1_CLK>;
clock-names = "xclk";
clock-frequency = <24000000>;
vdddo-supply = <&camera_vdddo_1v8>;
vdda-supply = <&camera_vdda_2v8>;
vddd-supply = <&camera_vddd_1v5>;
status = "ok";
port {
ov5645_2_ep: endpoint {
clock-lanes = <1>;
data-lanes = <0 2>;
remote-endpoint = <&csiphy0_ep>;
};
};
};
};
camera_primary_default: camera_primary_default {
mux_rst {
function = "gpio";
pins = "gpio23";
};
config_rst {
pins = "gpio23";
drive-strength = <16>;
bias-disable;
};
mux_mclk1 {
function = "cam_mclk";
pins = "gpio14";
};
config_mclk1 {
pins = "gpio14";
drive-strength = <16>;
bias-disable;
};
mux_enable {
function = "gpio";
pins = "gpio130";
};
config_enable {
pins = "gpio130";
drive-strength = <2>;
bias-pull-down;
output-high;
};
};
I am getting the following error during probe function:
[ 198.142180] i2c-qcom-cci a0c000.cci: master 1 queue 0 timeout
[ 198.144198] i2c-qcom-cci a0c000.cci: cci i2c xfer error -110

[ 198.154873] ov5645: probe of 6-003c failed with error -110
The camera is connected to CCI1. Can anyone please help me in fixing this issue? @Loic @architt @ljking @anon91830841
