2020-09-26leds: parse linux,default-trigger DT property in LED coreMarek Behún1-4/+0
Do the parsing of `linux,default-trigger` DT property to LED core. Currently it is done in many different drivers and the code is repeated. This patch removes the parsing from 23 drivers: an30259a, aw2013, bcm6328, bcm6358, cr0014114, el15203000, gpio, is31fl32xx, lm3532, lm36274, lm3692x, lm3697, lp50xx, lp8860, lt3593, max77650, mt6323, ns2, pm8058, pwm, syscon, tlc591xx and turris-omnia. There is one driver in drivers/input which parses this property on it's own. I shall send a separate patch there after this is applied. There are still 8 drivers that parse this property on their own because they do not pass the led_init_data structure to the registering function. I will try to refactor those in the future.

2019-07-25leds: lp8860: Use generic support for composing LED namesJacek Anaszewski1-19/+16
Switch to using generic LED support for composing LED class device name. While at it, avoid iterating through available child of nodes in favor of obtaining single expected child node using single call to of_get_next_available_child().

2018-01-08leds: lp8860: Various fixes to align with LED frameworkDan Murphy1-8/+5
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.

2015-03-03leds: lp8860: make use of devm_gpiod_get_optionalUwe Kleine-König1-5/+7
The probe function open coded a bad variant of devm_gpiod_get_optional using devm_gpiod_get and just ignoring all errors. In contrast to that devm_gpiod_get_optional returns NULL if there was no corresponding gpio specified in the device tree (or ACPI table) and fails if there is an error (or GPIOLIB is not enabled). Moreover since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output which allows some simplification.
