2020-09-26leds: parse linux,default-trigger DT property in LED coreMarek Behún1-2/+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.

Use helper variable dev instead of always writing &pdev->dev. Signed-off-by: Marek Behún <marek.behun@nic.cz> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Pavel Machek <pavel@ucw.cz>
2020-09-26leds: pm8058: use struct led_init_data when registeringMarek Behún1-5/+6
By using struct led_init_data when registering we do not need to parse `label` DT property. Moreover `label` is deprecated and if it is not present but `color` and `function` are, LED core will compose a name from these properties instead.

The dev_of_node function should be preferred.

2017-12-01leds: pm8058: Silence pointer to integer size warningBjorn Andersson1-1/+1
The pointer returned by of_device_get_match_data() doesn't have the same size as u32 on 64-bit architectures, causing a compile warning when compile-testing the driver on such platform. Cast the return value of of_device_get_match_data() to unsigned long and then to u32 to silence this warning.

2016-08-16leds: add PM8058 LEDs driverLinus Walleij1-0/+191
This adds a driver for the six PM8058 LEDs, three ordinary LEDs, two "flash" LEDs and one "keypad" LED. The "keypad" and "flash" LEDs are not really hard-wired to these usecases: for example on the APQ8060 Dragonboard, the "keypad" LED is instead used to drive an IR LED used for the proximity sensor. The "flash" LEDs are just ordinary high-current LED drivers.
