[media] coda: fix build error by making reset control optional

2014-08-01T18:27:14+00:00

make reset control optional for i.MX27

The patch "[media] coda: add reset control support" introduced a build failure
if CONFIG_RESET_CONTROLLER is disabled:

    drivers/media/platform/coda.c:3734:2: error: implicit declaration of
     function 'devm_reset_control_get'

Since not all SoCs containing CODA VPUs do have a system reset controller,
use devm_reset_control_get_optional to make it optional.

[media] soc_camera: add support for dt binding soc_camera drivers

2014-07-30T22:30:05+00:00

Add initial support for OF based soc-camera devices that may be used
by any of the soc-camera drivers. The driver itself will need converting
to use OF.

These changes allow the soc-camera driver to do the connecting of any
async capable v4l2 device to the soc-camera driver. This has currently
been tested on the Renesas Lager board.

It currently only supports one input device per driver as this seems
to be the standard connection for these devices.

Since we have get vdev by calling video_devdata() at the beginning of

again in the following code.

greater than 2. Prevent this by asserting downscale ratio to 2.
