Dear guys,
I'm currently working on a camera/ISP Linux driver project.Of course,I
want it to be a V4L2 driver,but I got a problem about how to design
the driver framework.
let me introduce the background of this ISP(Image signal processor) a
little bit.
1.The ISP has two output paths,first one
I think, the direct use of vb2_plane_cookie() is discouraged.
vb2_dma_contig_plane_dma_addr() should work for you.
I guess you mean vb2_dma_contig_plane_paddr
no, in the current kernel it's vb2_dma_contig_plane_dma_addr(). See

you need to include linux/i2c.h for this
no,

just use DEBUG ?
no, v4l2 use CONFIG_VIDEO_ADV_DEBUG

is that 1 correct ? i dont think so ...
every driver under media I see use this, so

Hi, Antti,
Thanks for taking the time to answer my request. However, I am afraid
I am not able to find the vendor drivers you mention - if I had I
would not have posted about it. No matter how much time I spend
scouring the Compro website I can only find Windows drivers - nothing
about

Hi,
I'm trying to add support for YUV420 format to mx2_camera.c soc-camera

In my system, an imx27_visstrim_m10 board, this host is connected to a
tvp5151 chip which is only
able to transfer pixels

Interesting idea, but it didn't worked. It deadlocks. I think it
locks since I2C-mux is controlled by I2C switch in same I2C bus,
not GPIO or some other HW.
Take a look at drivers/i2c/muxes/pca954x.c. You need to use

I've acked the patch on September the 6th and asked in the e-mail if you could
pick it and push it to v3.1. Is there anything else I need to do ?
