Hello all,
I have a custom board similar to sabreauto board. And I use fsl-yocto-3.14.28. I want to use 2 adv7180 devices. One for CSI-0 -> IPU-0, other for CSI-1 -> IPU-1. My device tree has below nopes.
v4l2_cap_0 {
compatible = "fsl,imx6q-v4l2-capture";
ipu_id = <0>;
csi_id = <0>;
mclk_source = <0>;
status = "okay";
};
v4l2_cap_1 {
compatible = "fsl,imx6q-v4l2-capture";
ipu_id = <1>;
csi_id = <1>;
mclk_source = <0>;
status = "okay";
};
adv7180_20: adv7180@20 {
compatible = "adv,adv7180";
reg = <0x20>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ipu1_2>;
clocks = <&clks IMX6QDL_CLK_CKO>;
clock-names = "csi_mclk";
DOVDD-supply = <®_3p3v>; /* 3.3v, enabled via 2.8 VGEN6 */
AVDD-supply = <®_3p3v>; /* 1.8v */
DVDD-supply = <®_3p3v>; /* 1.8v */
PVDD-supply = <®_3p3v>; /* 1.8v */
csi_id = <0>;
mclk = <24000000>;
mclk_source = <0>;
cvbs = <1>;
};
adv7180_21: adv7180@21 {
compatible = "adv,adv7180";
reg = <0x21>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ipu2_2>;
clocks = <&clks IMX6QDL_CLK_CKO>;
clock-names = "csi_mclk";
DOVDD-supply = <®_3p3v>; /* 3.3v, enabled via 2.8 VGEN6 */
AVDD-supply = <®_3p3v>; /* 1.8v */
DVDD-supply = <®_3p3v>; /* 1.8v */
PVDD-supply = <®_3p3v>; /* 1.8v */
csi_id = <1>;
mclk = <24000000>;
mclk_source = <0>;
cvbs = <1>;
};
Without any change v4l2_int_device_register for adv7180_int_device in drivers/media/platform/mxc/capture/adv7180.c couldn't success because of adv7180_int_device is declared statically. For first capture master there is no problem. adv7180 is attached to mxc_v4l2_cap0. But second adv7180 couldn't attach to mxc_v4l2_cap1. I have created second adv7180_int_device for second adv7180 and both of them are attached.
When i try ./mxc_v4l2_capture.out -d /dev/video1 -iw 720 -ih 576 -ow 720 -oh 576 -r 0 -fr 15 /mnt/nfs/test2.yuv, I get below error.
VIDIOC_DQBUF failed.
VIDIOC_QBUF failed
I tried /dev/video0 and dev/video1 and result is same.
I have applied patches for to camera input.
