mx6q csi driver ?

mx6q csi driver ?

[Philippe De Muyter]

Hi,

I try to write a linux driver for a cmos sensor connected to a sabresd
board, but I wonder where to continue.

I first considered using the freescale 3.10.17 beta kernel,
which has already a csi v4l2 driver (but using deprecated v4l2 internals).
That does not work at the moment because I need spi to configure my
sensor and spi does not work with that kernel on my sabresd board :(
I should also mention that reboot does not work either.

As I also had worked with linus's tree and currently have 3.14-rc4
working on my sabresd board, with functional spi and reboot, I tried
to port the freescale 3.10.17 v4l2 csi driver modules to 3.14-rc4,
but now my kernel is locked at startup (it does not even issue
one message after 'Uncompressing kernel...').

What would be the best way to write my CMOS sensor driver ?  (I aim to
push it to linus when finished), and are there more specific mailing lists
for either the freescale kernel or the mx6 csi driver ?

TIA

We already have patches for the CSI, for 3.14-rc+ and based on all the
latest and greatest v4l2 stuff.

Before posting those, we'd like to get the current move-ipu-out-of-
staging effort patch series resolved, then the video part will be one of
the next topics we'll address.
