| | | | | | | | | | | | | | | | | | The values of BCM6328_LED_MODE_ON and BCM6328_LED_MODE_OFF were named for active low LEDs.

* | leds: bcm6328: Reuse bcm6328_led_set() instead of copying its functionalitySimon Arlott2016-01-041-6/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | When ensuring a consistent initial LED state in bcm6328_led (as they may be blinking instead of on/off), the LED register is set using an inverted copy of bcm6328_led_set(). To avoid further errors relating to active low handling, call this function directly instead. As bcm6328_led_set() acquires the same spinlock again when updating the register, it is called after unlocking.

* | leds: turn off the LED and wait for completion on unregistering LED class deviceMilo Kim2016-01-041-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Workqueue, 'set_brightness_work' is used for scheduling brightness control. This workqueue is canceled when the LED class device is unregistered. Currently, LED subsystem handles like below. cancel_work_sync(&led_cdev->set_brightness_work) led_set_brightness(led_cdev, LED_OFF) However, this could be a problem. Workqueue is going to be canceled but LED device needs to be off. The worst case is null pointer access due to scheduling a workqueue. LED module is loaded. LED driver private data is allocated by using devm_zalloc(). LED module is unloaded. led_classdev_unregister() is called. cancel_work_sync() led_set_brightness(led_cdev, LED_OFF) schedule_work() if LED driver uses brightness_set_blocking() In the meantime, driver private data will be freed. ..scheduling.. brightness_set_blocking() callback is invoked. For the brightness control, LED driver tries to access private data but resource is removed! To avoid this problem, LED subsystem should turn off the brightness first and wait for completion. led_set_brightness(led_cdev, LED_OFF) flush_work(&led_cdev->set_brightness_work) It guarantees that LED driver turns off the brightness prior to resource management.

* | leds: call led_pwm_set() in leds-pwm to enforce default LED_OFFMarkus Hofstaetter2016-01-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some PWMs are disabled by default or the default pin setting does not match the LED_OFF state (e.g., active-low leds). Hence, the driver may end up reporting 0 brightness, but the leds are actually on using full brightness, because it never enforces its default configuration. So enforce it by calling led_pwm_set() after successfully registering the device. Tested on a Phytec phyFLEX i.MX6Q board based on kernel v3.19.5.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The transient trigger duration is documented to be in msec units, but is actually in jiffies units. Other time based triggers are in msec units as well. Fix the timer setup to convert from msec. This could break an existing userspace that worked around this problem, but exposing jiffies to userspace is just wrong and would break anyway if HZ is changed.

* | leds: core: Drivers shouldn't enforce SYNC/ASYNC brightness settingJacek Anaszewski2016-01-044-32/+19Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes SET_BRIGHTNESS_ASYNC and SET_BRIGHTNESS_SYNC flags. led_set_brightness() now calls led_set_brightness_nosleep() instead of choosing between sync and async op basing on the flags defined by the driver. From now on, if a user wants to make sure that brightness will be set synchronously, they have to use led_set_brightness_sync() API. It is now being made publicly available since it has become apparent that it is a caller who should decide whether brightness is to be set in a synchronous or an asynchronous way.

It removes from LED class drivers responsibility for using work queues on their own. In order to achieve this set_brightness_delayed callback is being modified to directly call one of available ops for brightness setting. led_set_brightness_async() function didn't set brightness in an asynchronous way in all cases. It was mistakenly assuming that all LED subsystem drivers used work queue in their brightness_set op, whereas only half of them did that. Since it has no users now, it is being removed.

* | leds: core: Add led_set_brightness_nosleep{nopm} functionsJacek Anaszewski2016-01-049-23/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds led_set_brightness_nosleep() and led_set_brightness_nopm() functions, that guarantee setting LED brightness in a non-blocking way. The latter is used from pm_ops context and doesn't modify the brightness cached in the struct led_classdev. Its execution always ends up with a call to brightness setting op - either directly or through a set_brightness_work, regardless of LED_SUSPENDED flag state. The patch also replaces led_set_brightness_async() with led_set_brightness_nosleep() in all places where the most vital was setting brightness in a non sleeping way but not necessarily asynchronously, which is not needed for non-blocking drivers.

* | leds: Rename brightness_set_sync op to brightness_set_blockingJacek Anaszewski2016-01-045-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial purpose of brightness_set_sync op, introduced along with the LED flash class extension, was to add a means for setting torch LED brightness as soon as possible, which couldn't have been guaranteed by brightness_set op. This patch renames the op to brightness_set_blocking, which describes its purpose in a more generic way. It is beneficial in view of the prospective changes in the LED core, aiming at removing the need for using work queues in LED class drivers that can sleep or use delays while setting brightness.
