[PATCH v3] go2001 hardware codec support

From: Thierry Escande
Date: Tue Jul 25 2017 - 13:40:40 EST

Hi,

This patch introduces the go2001 hardware codec driver.

Changes in v3:
- Replace crop iotcl with selection ones
- Use video dev device_caps field
- Return v4l2_ctrl_subscribe_event() for default case
- Fix start_streaming error handling
- Remove empty ctrl ops callbacks
- Avoid use of private ctrl structures
- Remove VB2_USERPTR support
- Remove format description strings

Changes in v2:
- Remove unneeded call to dma_cache_sync() on coherent dma buffer.

Following are the results of v4l2-compliance utility execution for both
/dev/video0 and /dev/video1 devices.

Note that the failing tests are due to un-initialized internal
structures of the driver not done through these unit tests.
