In your device tree binding documentation there is torch-gpio mentioned,
but you seem not to use it in the driver.
We have already LED Flash class (/drivers/leds/led-class-flash.c) for
this type of devices, which handles both torch and flash modes
(flash_strobe sysfs attribute is provided for strobing the flash).
The reference drivers using LED Flash class are still pending [1], but I
think that at least leds-aat1290 driver is almost ready for merging.
It controls very similar device to yours.
Another advantage of using LED Flash class is that it has been designed
to be compatible with Video for Linux 2 subsystem, which will allow for
registering LED Flash class devices as a V4L2 sub-devices.
Adding Sakari.
