/* Note that the cx25840 driver requires that the bridge driver calls the
|
|
v4l2_subdev's init operation in order to load the driver's firmware.
|
|
Without this the audio standard detection will fail and you will
|
|
only get mono.
|
|
|
|
Since loading the firmware is often problematic when the driver is
|
|
compiled into the kernel I recommend postponing calling this function
|
|
until the first open of the video device. Another reason for
|
|
postponing it is that loading this firmware takes a long time (seconds)
|
|
due to the slow i2c bus speed. So it will speed up the boot process if
|
|
you can avoid loading the fw as long as the video device isn't used. */
