Subject: [PATCH/RFC v10 00/19] LED / flash API integration

This patch set is a follow-up of the LED / flash API integration
series [1]. It is based on linux-next_20150108.

========================
Changes since version 9 :
========================

- switched to assigning sub-led related of_node to led_cdev->dev->of_node
  member which allowed for avoiding modifications around v4l-async
- reimplemented max77693 flash cell driver to avoid extensive use
  of macros
- added led-sources DT property and switched to using it
- switched to reporting flash faults in the LED subsystem in the form
  of human readable strings
- added available_sync_leds sysfs attribute to the LED Flash class
  and changed the semantics of flash_sync_strobe attribute
- made LED subsystem flash faults not depending on the V4L2 Flash ones
- applied various fixes and cleanups

========================
Changes since version 8:
========================

- added a new way of registering async sub-device
- switched to matching flash leds by DT phandles
- improved Device Tree bindings documentation
- split the drivers patches to LED Flash class
  and V4L2 Flash part
- fixed indicator leds handling in v4l2-flash
- applied various fixes an cleanups

========================
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
