Duration the flash should be on when the flash LED is in flash mode
(V4L2_FLASH_LED_MODE_FLASH). The unit should be microseconds (µs)
if possible.

+``V4L2_CID_FLASH_HW_STROBE_SIGNAL (boolean)``
+ Enable or disable the output of a hardware strobe signal. This is typically
+ set on a sensor that provides a hardware strobe output which is connected
+ to a flash device/LEDs. The flash device should then be configured to use
+ an external strobe source (V4L2_FLASH_STROBE_SOURCE_EXTERNAL).
