* leds: parse linux,default-trigger DT property in LED coreMarek Behún2020-09-261-3/+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.

* leds: various: use only available OF childrenMarek Behún2020-09-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various drivers count and iterate over OF children nodes via of_get_child_count and for_each_child_of_node. Instead they should use of_get_available_child_count and for_each_available_child_of_node, so that if a given node has the `status` property set to `disabled`, the child will be ignored.

* leds: add Panasonic AN30259A supportSimon Shields2018-09-101-0/+368
AN30259A is a 3-channel LED driver which uses I2C. It supports timed operation via an internal PWM clock, and variable brightness. This driver offers support for basic hardware-based blinking and brightness control.
