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>
