CSI Sensor integration in OMAP4460: Not getting interrupts for line start/frame start

Hi all,

I am integrating a new sensor (RAW10) with OMAP4460.
I have used V4L2 based driver to do so, I can see expected clock and data signals after configuring sensor.

However, I don't get ISS interrupts for line start/frame start, so application hangs in dequeue() call forever.

I have following doubts for inability to capture data.

1) ov5640_s_fmt() has following line: ov5640->pixel_rate->cur.val64 = ov5640_get_pclk(sd) / 16;

static unsigned long ov5640_get_pclk(struct v4l2_subdev *sd)
{
    struct ov5640 *ov5640 = to_ov5640(sd);
    unsigned long xvclk, vco, mipi_pclk;

    xvclk = clk_get_rate(ov5640->xvclk); // ov5640->xvclk is 19.2 MHz for my case

    vco = (xvclk / ov5640->clk_cfg.sc_pll_prediv) *
        ov5640->clk_cfg.sc_pll_mult;

    mipi_pclk = vco /
        ov5640->clk_cfg.sysclk_div /
        ov5640->clk_cfg.mipi_div;

    printk("######## ov5640_get_pclk: xvclk: %d vco: %d mipi_pclk: %d\n", xvclk, vco, mipi_pclk);
    return mipi_pclk;
}

What is significance of ov5640->pixel_rate->cur.val64 ? What should be the value for VGA, 24 fps, RGB10 with 1 data lane? How it is calculated?

What should be sysclk_div, mipi_div, sc_pll_prediv and sc_pll_mult for a specific resolution ?
