Hello,

This patch sets implements support for BT.656 and interlaced formats in
the OMAP3 ISP driver. Better late than never I suppose, although given
how long this has been on my to-do list there's probably no valid
excuse.
Thanks Laurent!

I hope to have time soon to test it :)
i wanted to try your patches but i'm having a problem (probably not
caused by your patches).

I merged media_tree master and omap3isp branches, applied your patches
and added camera platform data in pdata-quirks, but when loading the
omap3-isp driver i have:

omap3isp: clk_set_rate for cam_mclk failed

The returned value from clk_set_rate is -22 (EINVAL), but i can't see
any other debug message to track it down. Any ides?
I'm testing it on an igep proton (omap3530 version).
Hi Enrico,

please test the attached patch. It is based on Laurent's patches for the
clock and boot testes on an Gumstix Overo with an OMAP3530.
The patch looks good to me. Do you plan to submit it to mainline ?
I will submit it, if I have a running set-up.

At the moment the camera clock is half of the requested clock.

I have changed the ti,clock-mult of dpll4_m5x2_mul_ck to 1 to get the requested rate. But the omap3isp reports an unexpected cam_mclk rate (expected : 172800000, actual : 144000000).
