Changes in v2:
- Add A-b tags
- Switch to v4l2_ctrl_s_ctrl_int64() to acquire the control handler mutex
- Add error handling for v4l2_ctrl_s_ctrl_int64() and
imx214_pll_update()
- Replace

Replace the hard coded external clock frequency by the one read from
device tree.

Move clock frequency related parameters out of the constant register
sequences, such that the hard coded external clock frequency can be
replaced by a variable in the upcoming patches.

Add the first version of the virtio-media driver.
This driver acts roughly as a V4L2 relay between user-space and the
virtio virtual device on the host, so it is relatively simple, yet
unconventional. It doesn't use VB2 or other frameworks typically used in
a V4L2 driver, and most o

and after this patch imx214->clk_params = &imx214_clk_params[1];
