linux-toradex.git/include/media/ov7670.h, branch v4.1.17 Linux kernel for Apalis and Colibri modules [media] media: ov7670: Add possibility to disable pixclk during hblank 2013-02-08T16:35:06+00:00 Javier Martin javier.martin@vista-silicon.com 2013-01-29T10:26:38+00:00 ee95258ed3926f3aa2cf8d62e62cd51be466fe26 Some bridge drivers capture pixels during blanking periods if pixclk is enabled. In order to avoid capturing bogus data we need to disable pixclk in the sensor during those blanking periods.

[media] media: ov7670: add possibility to bypass pll for ov7675 2013-02-08T16:30:48+00:00 Javier Martin javier.martin@vista-silicon.com 2013-01-29T10:23:42+00:00 04ee6d92047e1ac68d4eb615119343f4f0fc57db For a frame rate of 30 fps a pixclk of 24MHz is needed. For those cases where the ov7670 has a clean 24MHz input (xvclk) the PLL can be bypassed. This will result in a value of clkrc of 1, which means that in practice pixclk = xvclk (input clock) Acked-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Javier Martin <javier.martin@vista-silicon.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

This move requires putting ov7670.h into include/media, but there are no code changes.
