[PATCH v4 0/3] leds: Introduce userspace leds driver

From: David Lechner
Date: Fri Sep 16 2016 - 15:17:23 EST


v2 changes:

* sort #includes
* fix typo in Kconfig
* Add Documentation text file

v3 changes:

* fix typos in docs
* rename "leds class" to "LED class" in docs
* rebase on linux-leds/for-next

v4 changes:

* Use devm_led_classdev_register() instead of led_classdev_register()
* Clarified how to create multiple devices in documentation
* uledmon.c now uses blocking reads instead of poll()
* Add some sanity checking on user-provided device name to make sure it is not
a directory name
* Reading from /dev/uleds allows any size read buffer - still only returns one
byte regardless of size
* Reading from /dev/uleds blocks until the brightness is changed
* LEDS_MAX_NAME_SIZE is reduced to 64 to match existing name size limit
* New patch to use LEDS_MAX_NAME_SIZE in drivers/leds/led-class.c
* Moved example code to tool/leds/uledmon.c (new patch with Makefile)
