First, I want to apologize for the spam.  I don't normally want to ask
for hand-holding, but after spending 4 solid days on this, I'm getting
frustrated, and I've tried to read the instructions, and the technical
reference manual is huge and somewhat overwhelming.

Once I get my hardware working and I develop a better understanding of
how this system works, I'll be more than happy to volunteer to help
test patches on my hardware.

I am not sure I fully understand how the media-ctl handles the
routing.  I just basically copied what I could find from some
documentation.  I looked for some documentation but I wasn't able to
find much.  Maybe you can point me to some.

I can share with you some of my device tree, and I'll try to explain
my connections.   Firstly, I have an i.MX6Q and i.MX6Q which share the
same device tree.

The CSI pins on the OV5640 camera go to i.MX6 pins:
CSI_CLK0M / CSI_CLK0P,
CSI_D0M / CSI_D0P,
CSI_D1M / CSI_D1P,

CSI_D2 and D3 pins on the processor are all floating, and CSI_REXT is
grounded through a 6.04k pull-down resistor.

I am not sure if these technically translate to CSI0, CSI1, or CSI2,
but I assumed the CSI2 since that's how the SabreSD board appears to
work.

The ov5640 is connected to i2c3 with the following tree entry:

ov5640: camera@10 {
    compatible = "ovti,ov5640";
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_ov5640>;
    reg = <0x10>;
    clocks = <&clks IMX6QDL_CLK_CKO>;
    clock-names = "xclk";
    DOVDD-supply = <&mipi_pwr>;
    AVDD-supply = <&mipi_pwr>;
    DVDD-supply = <&mipi_pwr>;
    reset-gpios = <&gpio3 26 GPIO_ACTIVE_LOW>;
    powerdown-gpios = <&gpio3 27 GPIO_ACTIVE_HIGH>;

    port {
        ov5640_to_mipi_csi2: endpoint {
        remote-endpoint = <&mipi_csi2_in>;
        clock-lanes = <0>;
        data-lanes = <1 2>;
    };
};

I will be the first person to admit, I don't understand how the
clock-lands and data-lanes interact with the mipi_csis and the camera,
but I tried to match the sabresd board device tree.

For the MIPI_CSI interface, I wasn't sure which ports are the proper
reference.  Looking at the sabresd board,  I used it as an example.  I
wasn't sure if port0 and reg 0 were the right options.
&mipi_csi {
    status = "okay";

    port@0 {
        reg = <0>;
        mipi_csi2_in: endpoint {
            remote-endpoint = <&ov5640_to_mipi_csi2>;
            clock-lanes = <0>;
            data-lanes = <1 2>;
        };
    };
};

There was one section of the sabresd board that I wasn't sure I
needed, because I am new to this camera stuff.  I wasn't thinking I
needed it, but I copied it  because the sabresd board had it.  I know
it has two cameras, but the interaction between the csi interface and
the ipu isn't clear to me.

&ipu1_csi1_from_mipi_vc1 {
        clock-lanes = <0>;
        data-lanes = <1 2>;
};


I am not 100% certain the following is correct, but I tried to disable
unwanted features to help save power, but it's quite possible it's
interfering with the settings i have above.

&ipu1_csi0 {
    status = "disabled";
};

&ipu2_csi0 {
    status = "disabled";
};

&mipi_dsi {
    status = "disabled";
};

I am ok with simple streaming to the screen.  I'm ok with converting
to video.  At this point, I'm trying to just simply see the camera
work.  :-)

I ported the entire ov5640 driver, but there appear to be some v4l
changes which preclude me from copying the whole driver.  I was hoping
to use as close to stock 4.14 LTS kernel since 4.19 isn't quite done
yet.  (I 'think' 4.19 will be an LTS kernel if I'm not mistaken, so
this kernel is open for discussion if we must transition to it)

My i.MX6 board is running some tests now, but I'll try to build
4.19-rc8 and share some logs.

I first went through the git commit logs for the ov5640 and tried to
grab anything with the word 'fix' in the headlines.  I'll try this
afternoon, to get a better feeling for which fixes were ported.  In
theory, I can go and request certain fixes to be backported too, but I
want to make sure they actually work before I waste people's time.
