Merge tag 'leds-for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED updates from Jacek Anaszewski: "In this cycle we've finally managed to contribute the patch set sorting out LED naming issues. Besides that there are many changes scattered among various LED class drivers and triggers. LED naming related improvements: - add new 'function' and 'color' fwnode properties and deprecate 'label' property which has been frequently abused for conveying vendor specific names that have been available in sysfs anyway - introduce a set of standard LED_FUNCTION* definitions - introduce a set of standard LED_COLOR_ID* definitions - add a new {devm_}led_classdev_register_ext() API with the capability of automatic LED name composition basing on the properties available in the passed fwnode; the function is backwards compatible in a sense that it uses 'label' data, if present in the fwnode, for creating LED name - add tools/leds/get_led_device_info.sh script for retrieving LED vendor, product and bus names, if applicable; it also performs basic validation of an LED name - update following drivers and their DT bindings to use the new LED registration API: - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114, leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt Other LED class improvements: - replace {devm_}led_classdev_register() macros with inlines - allow to call led_classdev_unregister() unconditionally - switch to use fwnode instead of be stuck with OF one LED triggers improvements: - led-triggers: - fix dereferencing of null pointer - fix a memory leak bug - ledtrig-gpio: - GPIO 0 is valid Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer, more complete driver exists, based on a generic driver for the AMD SOCs gpio-controller, supporting LEDs as well other devices: - drop profile field from priv data - drop iosize field from priv data - drop enum_apu_led_platform_types - drop superseeded apu2/3 led support - add pr_fmt prefix for better log output - fix error message on probing failure Other misc fixes and improvements to existing LED class drivers: - leds-ns2, leds-max77650: - add of_node_put() before return - leds-pwm, leds-is31fl32xx: - use struct_size() helper - leds-lm3697, leds-lm36274, leds-lm3532: - switch to use fwnode_property_count_uXX() - leds-lm3532: - fix brightness control for i2c mode - change the define for the fs current register - fixes for the driver for stability - add full scale current configuration - dt: Add property for full scale current. - avoid potentially unpaired regulator calls - move static keyword to the front of declarations - fix optional led-max-microamp prop error handling - leds-max77650: - add of_node_put() before return - add MODULE_ALIAS() - Switch to fwnode property API - leds-as3645a: - fix misuse of strlcpy - leds-netxbig: - add of_node_put() in netxbig_leds_get_of_pdata() - remove legacy board-file support - leds-is31fl319x: - simplify getting the adapter of a client - leds-ti-lmu-common: - fix coccinelle issue - move static keyword to the front of declaration - leds-syscon: - use resource managed variant of device register - leds-ktd2692: - fix a typo in the name of a constant - leds-lp5562: - allow firmware files up to the maximum length - leds-an30259a: - fix typo - leds-pca953x: - include the right header" * tag 'leds-for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds: (72 commits) leds: lm3532: Fix optional led-max-microamp prop error handling led: triggers: Fix dereferencing of null pointer leds: ti-lmu-common: Move static keyword to the front of declaration leds: lm3532: Move static keyword to the front of declarations leds: trigger: gpio: GPIO 0 is valid leds: pwm: Use struct_size() helper leds: is31fl32xx: Use struct_size() helper leds: ti-lmu-common: Fix coccinelle issue in TI LMU leds: lm3532: Avoid potentially unpaired regulator calls leds: syscon: Use resource managed variant of device register leds: Replace {devm_}led_classdev_register() macros with inlines leds: Allow to call led_classdev_unregister() unconditionally leds: lm3532: Add full scale current configuration dt: lm3532: Add property for full scale current. leds: lm3532: Fixes for the driver for stability leds: lm3532: Change the define for the fs current register leds: lm3532: Fix brightness control for i2c mode leds: Switch to use fwnode instead of be stuck with OF one leds: max77650: Switch to fwnode property API led: triggers: Fix a memory leak bug ...
