2020-09-30leds: tca6507: use fwnode API instead of OFMarek Behún1-37/+29
Convert to use fwnode API instead of OF. It is more generic and if someone wants to use this driver without device-tree yet still, they will be able to via swnode fwnodes.

2020-09-26leds: parse linux,default-trigger DT property in LED coreMarek Behún24-72/+5
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.

2020-09-26leds: syscon: use struct led_init_data when registeringMarek Behún1-3/+4
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.

2020-09-26leds: lm36274: use platform device as parent of LEDMarek Behún1-2/+2
Instead of registering LED under the MFD device, this driver sets the parent of the LED it is registering to the parent of the MFD device (the I2C client device). Because of this we cannot use devres for LED registration, since it can result in use-after-free, see commit a0972fff0947 ("leds: lm36274: fix use-after-free on unbind"). The only other in-tree driver that also registers under the MFD device (drivers/regulator/lm363x-regulator.c) sets the parent to the MFD device. Set the parent of this LED to the MFD device, instead of the I2C client device.

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. Previously if the `label` DT property was not present, the code composed name for the LED in the form "parent_name::" For backwards compatibility we therefore set init_data->default_label = ":"; so that the LED will not get a different name if `label` property is not present, nor are `color` and `function`.

2020-09-26leds: pwm: Allow automatic labels for DT based devicesAlexander Dahl1-1/+2
If LEDs are configured through device tree and the property 'label' is omitted, the label is supposed to be generated from the properties 'function' and 'color' if present. While this works fine for e.g. the 'leds-gpio' driver, it did not for 'leds-pwm'. The reason is, you get this label naming magic only if you add a LED device through 'devm_led_classdev_register_ext()' and pass a pointer to the current device tree node. For the following node from dts the LED appeared as 'led-5' in sysfs before and as 'red:debug' after this change. pwm_leds { compatible = "pwm-leds"; led-5 { function = LED_FUNCTION_DEBUG; color = <LED_COLOR_ID_RED>; pwms = <&pwm0 2 10000000 0>; max-brightness = <127>; linux,default-trigger = "heartbeat"; panic-indicator; }; }; Signed-off-by: Alexander Dahl <[email protected]> Cc: Marek Behún <[email protected]> Signed-off-by: Pavel Machek <[email protected]>
