iMX8QM OV5640 5MP Camera Greenish Overlay

Hi,

 

In iMX8QM custom board with 4.14.98 Kernel BSP, we are facing Greenish overlay and captured image in OV5640 Camera with 'QSXGA_2592_1944' (5MP) resolution.

On other lower resolution like (1080p,720p) the camera overlay and capture is working fine.

 

The driver we are using is ,

drivers/media/platform/imx8/ov5640_mipi_v3.c

The DTS entry as below,

&mipi_csi_0 {
#address-cells = <1>;
#size-cells = <0>;
status = "okay";

port@0 {
reg = <0>;
mipi_csi0_ep: endpoint {
remote-endpoint = <&ov5640_mipi_ep>;
data-lanes = <1 2>;
};
};
};

&i2c0_mipi_csi0 {
#address-cells = <1>;
#size-cells = <0>;
clock-frequency = <400000>;
status = "okay";

ov5640_mipi: ov5640_mipi@3c {
compatible = "ovti,ov5640_mipi_v3";
reg = <0x3c>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_mipi_csi0>;
clocks = <&clk IMX8QM_24MHZ>;
mclk = <24000000>;
mclk_source = <0>;
clock-names = "csi_mclk";
csi_id = <0>;
mipi_csi;
status = "okay";
port {
ov5640_mipi_ep: endpoint {
remote-endpoint = <&mipi_csi0_ep>;
};
};
};
};

 

Is there any kernel patch/workaround is available to fix this issue?

 

Note: The Greenish overlay captured image is attached along this post.
