Subject: [PATCH] BCM2835-V4L2: Increase minimum resolution to 32x32
https://github.com/raspberrypi/linux/issues/1498 showed
up that 16x16 is failing to work on the GPU for some reason.
GPU bug being tracked on
https://github.com/raspberrypi/firmware/issues/607
Workaround here by increasing minimum resolution via V4L2
to 32x32.
