This patch set is a follow-up of the LED / flash API integration
series [1].

========================
Changes since version 7:
========================

- removed explicit support for indicator leds from
LED Flash class - indicator leds will be registered
as a separate LED Flash class devices
- added flash_sync_strobe sysfs attribute and related
V4L2_CID_FLASH_SYNC_STROBE control
- changed the way of matching V4L2 Flash sub-devices
in a media device, which entailed modification in
v4l2-async driver
- modified max77693 DT bindings documentation
- applied various fixes an cleanups

========================
Changes since version 6:
========================

- removed addition of public LED subsystem API for setting
torch brightness in favour of internal API for
synchronous and asynchronous led brightness level setting
- fixed possible race condition upon creating LED Flash class
related sysfs attributes

========================
Changes since version 5:
========================

- removed flash manager framework - its implementation needs
further thorough discussion.
- removed external strobe facilities from the LED Flash Class
and provided external_strobe_set op in v4l2-flash. LED subsystem
should be strobe provider agnostic.

Thanks,
Jacek Anaszewski
