Re: [PATCH] V4L: soc-camera: provide support for S_INPUT.

Hi Guennadi, First question: you probably also want to patch soc_camera_g_input() and soc_camera_enum_input(). But no, I do not know how. The video subdevice operations do not seem to provide a way to query subdevice routing capabilities, so, I've got no idea how we're supposed to support

Re: [PATCH] V4L: soc-camera: provide support for S_INPUT.

gain you anything as far as I can tell since the subdevice simply does not know which inputs/outputs are actually hooked up. It's the top level driver that has that information (usually passed in through board/card info structures). Regards, Scott -- To unsubscribe from this list: send

v4l: how to get blanking clock count?

Re: v4l: how to get blanking clock count?

I the case of your bridge, that may not be possible, but that's the only one I've heard of so I think it's definitely a special case. In that case the sensor driver can't be allowed to change the blanking periods while streaming is ongoing. I agree, it's just a matter of adding proper logic

Re: v4l: how to get blanking clock count?

If I disable this interrupt, other errors like fifo underflow are ignored. Perhaps I can add a parameter in platform data to let user decide to register this interrupt or not. I think a more generic solution would be preferrable. If that causes ignoring real errors, that's of course bad. I

Yes, the MMU version of remap_pfn_range() does permit non-page-aligned `addr' (at least, if the userspace maaping is a non-COW one). But I suspect that was an implementation accident - it is a nonsensical thing to do, isn't it? The MMU cannot map a bunch of kernel pages onto a
