This patch set is a follow-up of the LED / flash API integration series [1]. It is based on linux-next_20150304 ======================== Changes since version 11 : ======================== - removed synchronized strobe feature from LED Flash class, as it turned out to be not fitting for sysfs interface. The V4L2 part can cover this in the future. - Improved external strobe handling for AAT1290 - added removing led-triggers on v4l2-flash sub-device open - applied minor improvements and cleanups ======================== Changes since version 10 : ======================== - added to the v4l2-flash sub-device driver the support for flash LED devices with non-linear brightness setting - improved current setting in the max77693-led driver - added ABI documentation for flash LED sysfs attributes - improved synchronized LEDs related sysfs attributes in the LED Flash class - applied various fixes and cleanups ======================== 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.
