2014-11-14[media] platform: Make use of media_bus_format enumBoris BREZILLON1-10/+9
In order to have subsytem agnostic media bus format definitions we've moved media bus definition to include/uapi/linux/media-bus-format.h and prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT. Reference new definitions in all platform drivers.

2014-08-21[media] omap3isp: resizer: Protect against races when updating cropLaurent Pinchart1-12/+31
When updating the crop rectangle during streaming, the IRQ handler will reprogram the resizer after the current frame. A race condition currently exists between the set selection operation and the IRQ handler: if the set selection operation is called twice in a row and the IRQ handler runs only during the second call, it could reprogram the hardware with partially updated values. Use a spinlock to protect against that.

2014-08-21[media] omap3isp: resizer: Remove slow debugging message from interrupt handlerLaurent Pinchart1-8/+9
The resizer_set_input_size() function prints a debugging message with the input width and height values. As the function is called from interrupt context, printing that message to the serial console could slow down the interrupt handler and cause it to miss the start of the next frame, causing image corruption. Fix this by reorganizing the resizer debug messages. The driver now prints the input size, the crop rectangle and the output size in the set selection handler instead of scattering debug messages in various places.

2014-08-21[media] omap3isp: resizer: Remove needless variable initializationsLaurent Pinchart1-6/+6
There's no need to initialize local variables to zero when they're explicitly assigned another value right after. Remove the needless initializations.
