HDMI input on i.MX6 using IPU

Hi,

I have modified both Steve's and Philipp's code, in order to get
something able to get frames from an ADV7611.
Right now, I am back to Philipp's base of code, rebased on top of
media-tree, and everything works fine, except the very last link
between SFMC and IDMAC (using media controller).
Here is a status.

The code is here :
https://github.com/Vodalys/linux-2.6-imx/tree/media-tree-zabel

I am using a DT with this simple connection between adv7611 and IPU :
&ipu1_csi0 {
    csi0_from_hdmi: endpoint {
        remote-endpoint = <&hdmi0_out>;
    };
};

hdmiin1: adv7611@4c {
    compatible = "adi,adv7611";
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_csi0>;
    reset-gpios = <&gpio1 20 GPIO_ACTIVE_LOW>;
    reg = <0x4c 0x68 0x66 0x64 0x62
        0x60 0x5e 0x5c 0x5a 0x58 0x56
        0x54 0x52>;
    reg-names = "main", "avlink", "cec", "infoframe", "esdp",
        "dpp", "afe", "rep", "edid", "hdmi", "test",
        "cp", "vdp";
    ports {
        #address-cells = <1>;
        #size-cells = <0>;
        port@0 {
            reg = <0>;
        };
        port@1 {
            reg = <1>;
            hdmi0_out: endpoint@1 {
                remote-endpoint = <&csi0_from_hdmi>;
                bus-width = <16>;
            };
        };
    };
};

It seems to be pretty good, I can configure mbus format, etc.

Now, I want to get the stream from /dev/video0 so, entity is imx-ipuv3-camera.2.
If I do this (according to topology it seems ok) :
$> media-ctl -v -l '"IPU0 SMFC0":1->"imx-ipuv3-camera.2":0[1]'
Opening media device /dev/media0
Enumerating entities
Found 33 entities
Enumerating pads and links
Setting up link 5:1 -> 2:0 [1]
Opening media device /dev/media0
media_setup_link: Unable to setup link (Invalid argument)

 "IPU0 SMFC0":1->"imx-ipuv3-camera.2":0[1]
                                         ^
Unable to parse link: Invalid argument (22)

I added a lot of printk() and I can get to :
[  208.010610] [ipu_find_link] find link IPU0 SMFC0(2):1 ->
imx-ipuv3-camera.2(234):0 in ipu_links
[  208.019372] [ipu_smfc_link_setup] link not found

This means that in ipu_find_link, imx-ipuv3-camera.2 is not found. The
234 is 256-22 as ipu_find_link returns -22 in a u8.
The code which breaks is here :
https://github.com/Vodalys/linux-2.6-imx/blob/media-tree-zabel/drivers/gpu/ipu-v3/ipu-media.c#L347

I can understand why the entity is not found, it does not existe as
such in the ipu_links array.
I think the issue is at the create of the imx-ipuv3-csi device but not
sure at all, and I would really appreciate some help in debugging
this.
I can see a FIXME in the code, but don't know if this is related, nor
how to solve it :
https://github.com/Vodalys/linux-2.6-imx/blob/media-tree-zabel/drivers/media/platform/imx/imx-ipuv3-csi.c#L1196

I think that when this final link will be ok, I will be able start
streaming some frames from adv7611, and this driver will be pretty
nice to be reviewed.

Thanks in advance,
JM
