Hi Linus, Besides regular driver updates, we introduce a portion of LED core improvements, that allow to avoid the need for using work queues in the LED class drivers, that set brightness in a blocking way. Affected LED class drivers are being optimized accordingly. Please note that in case of drivers/leds/leds-pca9532.c a conflict can occur due to the patch [1], if GPIO updates are applied before LED updates. In the opposite case the patch applies correctly with 3way merge. The following changes since commit 168309855a7d1e16db751e9c647119fe2d2dc878: Linux 4.4-rc8 (2016-01-03 15:15:37 -0800) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds.git tags/leds-for-4.5 for you to fetch changes up to 522f17e1214cf112e62cff56150964d8b68b94b2: leds: add HAS_IOMEM dependency to LEDS_BCM6328/LEDS_BCM6358 (2016-01-04 09:57:41 +0100) [1] https://patches.linaro.org/58284/ Best Regards, Jacek Anaszewski ---------------------------------------------------------------- - LED core improvements: - use EXPORT_SYMBOL_GPL consistently, - add two new LED_BLINK_ flags, - rename brightness_set_sync op to brightness_set_blocking, - add led_set_brightness_nosleep{nopm} functions, - use set_brightness_work for the blocking op, - drivers shouldn't enforce SYNC/ASYNC brightness setting, - turn off the LED and wait for completion on unregistering LED class device, - add managed version of led_trigger_register, - add description of brightness setting API to the LED class doc. - Remove work queues from drivers: leds-tlc591xx, leds-88pm860x, leds-adp5520, leds-bd2802, leds-blinkm, leds-lm3533, leds-lm3642, leds-pca9532, leds-lp3944, leds-lp55xx, leds-lp8788, leds-lp8860, leds-pca955x, leds-pca963x, leds-wm831x, leds-da903x, leds-da9052, leds-dac124d085, leds-lt3593, leds-max8997, leds-mc13783, leds-regulator, leds-wm8350, leds-max77693, leds-aat1290, leds-ktd2692, leds-gpio, leds-pwm, leds-lm355x, leds-ns2. - Replace brightness_set op with a new brightness_set_blocking op to make the drivers compatible with led triggers: leds-ipaq-micro, leds-powernv. - Add missing of_node_put: leds-ktd2692, leds-aat1290, leds-max77693. - Make the driver explicitly non-modular: ledtrig-cpu, ledtrig-ide-disk, leds-syscon. - Improvements to leds-bcm6328: - reuse bcm6328_led_set() instead of copying its functionality, - swap LED ON and OFF definitions, - improve blink support, - simplify duplicated unlock in bcm6328_blink_set, - add little endian support, - remove unneded lock when checking initial LED status, - add HAS_IOMEM dependency, - code cleaning. - Improvements to leds-bcm6358: - use bcm6358_led_set() in order to get rid of the lock, - merge bcm6358_led_mode and bcm6358_led_set, - add little endian support, - remove unneded lock when checking initial LED status, - add HAS_IOMEM dependency, - remove unneeded busy status check. - Call led_pwm_set() in leds-pwm to enforce default LED_OFF. - Fix duration to be msec instead of jiffies: ledtrig-transient. - Removing NULL check: leds-powernv. - Use platform_register/unregister_drivers(): leds-sunfire. - Fix module license specification: ledtrig-oneshot. - Fix driver description and make license match the header: leds-pwm. - Remove checking for state < 1 in flash_strobe_store(): led-class-flash. - Use led_set_brightness_sync for torch brightness: v4l2-flash-led-class ---------------------------------------------------------------- Andrew Lunn (23): leds: tlc591xx: Remove work queue leds: 88pm860x: Remove work queue leds: adp5520: Remove work queue leds: bd2802: Remove work queue leds: blinkm: Remove work queue leds: lm3533: Remove work queue leds: lm3642: Remove work queue leds: pca9532: Remove work queue for LEDs. leds: lp3944: Remove work queue leds: lp55xx: Remove work queue leds: lp8788: Remove work queue leds: lp8860: Remove work queue leds: pca955x: Remove work queue leds: pca963x: Remove work queue leds: wm831x: Remove work queue leds: da903x: Remove work queue leds: da9052: Remove work queue leds: dac124d085: Remove work queue leds: lt3593: Remove work queue leds: max8997: Remove unneeded workqueue include leds: mc13783: Remove work queue leds: regulator: Remove work queue leds: wm8350: Remove work queue Heiner Kallweit (1): leds: core: add managed version of led_trigger_register Ingi Kim (1): leds: ktd2692: Add missing of_node_put Jacek Anaszewski (20): leds: core: Use EXPORT_SYMBOL_GPL consistently leds: core: Add two new LED_BLINK_ flags leds: Rename brightness_set_sync op to brightness_set_blocking leds: core: Add led_set_brightness_nosleep{nopm} functions leds: core: Use set_brightness_work for the blocking op leds: core: Drivers shouldn't enforce SYNC/ASYNC brightness setting Documentation: leds: Add description of brightness setting API leds: max77693: Remove work queue leds: aat1290: Remove work queue leds: ktd2692: Remove work queue media: flash: use led_set_brightness_sync for torch brightness leds: gpio: Remove work queue leds: pwm: remove work queue leds: lm355x: Remove work queue leds: flash: Remove checking for state < 1 in flash_strobe_store() leds: ns2: Remove work queue leds: ipaq-micro: Implement brightness_set_blocking op leds: powernv: Implement brightness_set_blocking op leds: aat1290: Add missing of_node_put leds: max77693: Add missing of_node_put Markus Hofstaetter (1): leds: call led_pwm_set() in leds-pwm to enforce default LED_OFF Milo Kim (1): leds: turn off the LED and wait for completion on unregistering LED class device Paul Gortmaker (3): leds: ledtrig-cpu: Make the driver explicitly non-modular leds: ledtrig-ide-disk: Make the driver explicitly non-modular leds: syscon: Make the driver explicitly non-modular Rob Herring (1): leds: ledtrig-transient: fix duration to be msec instead of jiffies Saurabh Sengar (1): leds: powernv: removing NULL check Simon Arlott (2): leds: bcm6328: Reuse bcm6328_led_set() instead of copying its functionality leds: bcm6328: Swap LED ON and OFF definitions Thierry Reding (1): leds: sunfire: Use platform_register/unregister_drivers() Uwe Kleine-König (2): leds: triggers: oneshot: fix module license specification leds: pwm: fix driver description and make license match the header Vegard Nossum (1): leds: add HAS_IOMEM dependency to LEDS_BCM6328/LEDS_BCM6358 Álvaro Fernández Rojas (10): leds: bcm6328: code cleaning leds: bcm6328: remove unneded lock when checking initial LED leds: bcm6358: Use bcm6358_led_set() in order to get rid of the lock leds: bcm6358: remove unneded lock when checking initial LED status leds: bcm6328: add little endian support leds: bcm6358: add little endian support leds: bcm6328: simplify duplicated unlock in bcm6328_blink_set leds: bcm6358: merge bcm6358_led_mode and bcm6358_led_set leds: bcm6328: improve blink support leds: bcm6358: remove unneeded busy status check Documentation/leds/leds-class.txt | 13 +++ drivers/leds/Kconfig | 2 + drivers/leds/led-class-flash.c | 8 +- drivers/leds/led-class.c | 11 ++- drivers/leds/led-core.c | 120 ++++++++++++++++++------- drivers/leds/led-triggers.c | 28 ++++++ drivers/leds/leds-88pm860x.c | 23 ++--- drivers/leds/leds-aat1290.c | 59 ++++-------- drivers/leds/leds-adp5520.c | 26 ++---- drivers/leds/leds-bcm6328.c | 63 +++++++------ drivers/leds/leds-bcm6358.c | 37 ++++---- drivers/leds/leds-bd2802.c | 39 +++----- drivers/leds/leds-blinkm.c | 87 ++++-------------- drivers/leds/leds-da903x.c | 46 ++++------ drivers/leds/leds-da9052.c | 39 +++----- drivers/leds/leds-dac124s085.c | 38 +++----- drivers/leds/leds-gpio.c | 62 +++++-------- drivers/leds/leds-ipaq-micro.c | 6 +- drivers/leds/leds-ktd2692.c | 50 +++-------- drivers/leds/leds-lm3533.c | 30 ++----- drivers/leds/leds-lm355x.c | 85 ++++++------------ drivers/leds/leds-lm3642.c | 73 +++++---------- drivers/leds/leds-lp3944.c | 32 ++----- drivers/leds/leds-lp5521.c | 11 +-- drivers/leds/leds-lp5523.c | 10 +-- drivers/leds/leds-lp5562.c | 11 +-- drivers/leds/leds-lp55xx-common.c | 12 ++- drivers/leds/leds-lp55xx-common.h | 6 +- drivers/leds/leds-lp8501.c | 11 +-- drivers/leds/leds-lp8788.c | 48 +++++----- drivers/leds/leds-lp8860.c | 27 ++---- drivers/leds/leds-lt3593.c | 33 +++---- drivers/leds/leds-max77693.c | 58 +++--------- drivers/leds/leds-max8997.c | 1 -
