  12 /*
  13  * Note that the cx25840 driver requires that the bridge driver calls the
  14  * v4l2_subdev's load_fw operation in order to load the driver's firmware.
  15  * This will load the firmware on the first invocation (further ones are NOP).
  16  * Without this the audio standard detection will fail and you will
  17  * only get mono.
  18  * Alternatively, you can call the reset operation (this can be done
  19  * multiple times if needed, each invocation will fully reinitialize
  20  * the device).
  21  *
  22  * Since loading the firmware is often problematic when the driver is
  23  * compiled into the kernel I recommend postponing calling this function
  24  * until the first open of the video device. Another reason for
  25  * postponing it is that loading this firmware takes a long time (seconds)
  26  * due to the slow i2c bus speed. So it will speed up the boot process if
  27  * you can avoid loading the fw as long as the video device isn't used.
