[PATCH/RFC v12 00/19] LED / flash API integration
From: Jacek Anaszewski
Date: Wed Mar 04 2015 - 11:15:44 EST
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.
Thanks,
Jacek Anaszewski
