Marek Behún	c49d6cab0d	leds: parse linux,default-trigger DT property in LED core 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: lp50xx: Fix an error handling path in 'lp50xx_probe_dt()'

In case of memory allocation failure, we must release some resources as
done in all other error handling paths of the function.

'goto child_out' instead of a direct return so that 'fwnode_handle_put()'
is called when we break out of a 'device_for_each_child_node' loop.

leds: parse linux,default-trigger DT property in LED core

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: lp50xx: Add the LP50XX family of the RGB LED driver

Introduce the LP5036/30/24/18/12/9 RGB LED driver.
The difference in these parts are the number of
LED outputs where the:

LP5036 can control 36 LEDs
LP5030 can control 30 LEDs
LP5024 can control 24 LEDs
LP5018 can control 18 LEDs
LP5012 can control 12 LEDs
LP5009 can control 9 LEDs

The device has the ability to group LED outputs into control banks
so that multiple LED banks can be controlled with the same mixing and
brightness. Or the LED outputs can also be controlled independently.
