leds: add driver for support Mellanox regmap LEDs for BMC and x86 platform

2018-02-19T20:09:20+00:00

Driver obtains LED devices according to system configuration and creates
devices in form: "devicename:color:function", like
The full path is to be:
/sys/class/leds/mlxreg\:status\:amber/brightness
After timer trigger activation:
echo timer > /sys/class/leds/mlxreg\:status\:amber/trigger
Attributes for LED blinking will appaer in sysfs infrastructure:
/sys/class/leds/mlxreg\:status\:amber/delay_off
/sys/class/leds/mlxreg\:status\:amber/delay_on

LED setting is controlled through the on-board programmable devices,
which exports its register map. This device could be attached to any
bus type, for which register mapping is supported.

leds: lp8860: Various fixes to align with LED framework

2018-01-08T20:28:12+00:00

Update the driver to conform with the LED framework:
 - use devm_led_classdev_register
 - destroy mutex on exit
 - remove dependency on CONFIG_OF in the driver and move
   to the Kconfig
 - update the MODULE_LICENSE to GPL v2
 - remove setting of MAX brightness as the LED framework
   does this.

Pull LED updates from Jacek Anaszewski:
 "LED class drivers improvements:

  leds-pca955x:
   - add Device Tree support and bindings
   - use devm_led_classdev_register()
   - add GPIO support
   - prevent crippled LED class device name
   - check for I2C errors

  leds-gpio:
   - add optional retain-state-shutdown DT property
   - allow LED to retain state at shutdown

  leds-tlc591xx:
   - merge conditional tests
   - add missing of_node_put

  leds-powernv:
   - delete an error message for a failed memory allocation in
     powernv_led_create()

  leds-is31fl32xx.c
   - convert to using custom %pOF printf format specifier

  Constify attribute_group structures in:
   - leds-blinkm
   - leds-lm3533

  Make several arrays static const in:
   - leds-aat1290
   - leds-lp5521
   - leds-lp5562
   - leds-lp8501"

media: leds: as3645a: add V4L2_FLASH_LED_CLASS dependency

2017-09-05T20:32:45+00:00

We get a link error when V4L2_FLASH_LED_CLASS=m and AS3645A is built-in:

drivers/leds/leds-as3645a.o: In function `as3645a_v4l2_setup':
leds-as3645a.c:(.text+0x258): undefined reference to `v4l2_flash_init'

drivers/leds/leds-as3645a.o: In function `as3645a_remove':
leds-as3645a.c:(.text+0x784): undefined reference to `v4l2_flash_release'

This adds the same Kconfig dependency that the other V4L2 flash
drivers in drivers/leds use, to avoid that broken configuration.
