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
This patch adds support for the go2001 PCI codec driver. This hardware
is present on ChromeOS based devices like the Acer ChromeBox and Acer/LG
