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.

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.

Add a LED flash class driver for the as3654a flash controller. A V4L2 flash
driver for it already exists (drivers/media/i2c/as3645a.c), and this driver
is based on that.

leds: pca955x: add GPIO support

2017-08-14T20:22:37+00:00

The PCA955x family of chips are I2C LED blinkers whose pins not used
to control LEDs can be used as general purpose I/Os (GPIOs).

The following adds such a support by defining different operation
modes for the pins (See bindings documentation for more details). The
pca955x driver is then extended with a gpio_chip when some of pins are
operating as GPIOs. The default operating mode is to behave as a LED.

The GPIO support is conditioned by CONFIG_LEDS_PCA955X_GPIO.

leds: Remove SEAD-3 driver

2017-06-19T18:56:47+00:00

SEAD3 is using the generic syscon & regmap based register-bit-led
driver as of commit c764583f40b8 ("MIPS: SEAD3: Use register-bit-led
driver via DT for LEDs") merged in the v4.9 cycle. As such the custom
SEAD-3 LED driver is now unused, so remove it.

leds: cpcap: new driver

2017-03-29T19:02:27+00:00

Motorola CPCAP is a PMIC (power management integrated circuit) found
in multiple smartphones. This driver adds support for the chip's LED
controllers. This introduces support for all controllers used by the
Droid 4. According to Motorola's driver (no datasheets available)
there a couple of more LED controllers. I did not add support for
them, since I cannot verify that they work with my modifications.
