Subject: media: i2c: ov01a10: Change default vblank value to a vblank resulting in 30 fps
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ea444f30f6e37048939a0e1056749d7afc190dd5;p=thirdparty%2Fkernel%2Flinux.git

media: i2c: ov01a10: Change default vblank value to a vblank resulting in 30 fps

The ov01a10 is quite a small sensor, which does not capture a lot of
light, increase the default vblank so that the sensor runs at 30 fps
by default, doubling the default exposure.
