Subject[GIT PULL] LED subsystem updates for 4.5
Date
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/

----------------------------------------------------------------
- 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
