Linux/AM5728: ADV7842 Subdevice Driver

Tool/software: Linux

Hello,

we connected a custom adv7842 board with the vip on the evm5728.

The adv7842 video device driver included in the kernel 4.4.19 doesn't support the device tree. So I made the following changes in the probe function:

1. Set platform data manually (could later be retrieved from device tree)

2. Call v4l2_async_register_subdev(sd) at end of probe function

No other changes are made in the driver.

static int adv7842_probe(struct i2c_client *client,
const struct i2c_device_id *id)

struct adv7842_state *state;
static const struct v4l2_dv_timings cea640x480 =
V4L2_DV_BT_CEA_640X480P59_94;
struct adv7842_platform_data *pdata;
struct v4l2_ctrl_handler *hdl;
struct v4l2_subdev *sd;
u16 rev;
int err;

/* Check if the adapter supports the needed features */
if (!i2c_check_functionality(client->adapter, I2C_FUNC_SMBUS_BYTE_DATA))
return -EIO;

    port {

        remote-endpoint = <&vin3a>;

};

&vin3a {

  endpoint {

As you can see the vip is bound to the adv7842 subdevice. The problem is that no /dev/video1 device is registered. What could be the reason for that? Is it allowed to manually set the platform data as I did it in the probe function?

I really would appreciate your help since I am new to v4l2 an linux in general. 

Thanks and have e nice day
