leds: lp5521/5523: Remove duplicate mutex

2014-01-10T22:48:07Z

It can be a problem when a pattern is loaded via the firmware interface. LP55xx common driver has already locked the mutex in 'lp55xx_firmware_loaded()'. So it should be deleted. On the other hand, locks are required in store_engine_load() on updating program memory. Reported-by: Pali Rohár Reported-by: Pavel Machek Signed-off-by: Milo Kim Signed-off-by: Bryan Wu Cc:

leds: pwm: Fix for deferred probe in DT booted mode

2013-12-02T19:53:17Z

We need to make sure that the error code from devm_of_pwm_get() is the one the module returns in case of failure. Restructure the code to make this possible for DT booted case. With this patch the driver can ask for deferred probing when the board is booted with DT. Fixes for example omap4-sdp board's keyboard backlight led.

leds: lp55xx: handle enable pin in driver

2013-10-25T17:13:25Z

This patch moves the handling of the chip's enable pin from the board code into the driver. It also updates all board-code files using the driver to incorporate this change. This is needed for device tree support of the enable pin. Signed-off-by: Sebastian Reichel Acked-by: Linus Walleij Acked-by: Tony Lindgren Signed-off-by: Bryan Wu

leds-gpio: of: led should not be created if its status is disabled

2013-10-25T17:12:55Z

now the leds-gpio driver will create every child led node without checking the status is disabled or not. for example, if we have a led node like d3, and its status is disabled: leds { d3 { label = "d3"; gpios = <&pioE 24 0>; status = "disabled"; }; }; we except the d3 should not be created. And the gpios should not be request as well. But current driver will create d3 and request its gpio. This patch fix this by using for_each_available_child_of_node() and of_get_available_child_count() to enumerate all child nodes. So the disabled node will be inavailable.

leds: Added driver for the NXP PCA9685 I2C chip

2013-10-22T17:57:35Z

The NXP PCA9685 supports 16 channels/leds using a 12-bit PWM (4095 levels of brightness) This driver supports configuration using platform_data. Signed-off-by: Maximilian Güntner Signed-off-by: Bryan Wu

leds: pwm: Remove redundant of_match_ptr

2013-10-22T17:57:34Z

The data structure of_match_ptr() protects is always compiled in. Hence of_match_ptr() is not needed. Signed-off-by: Sachin Kamat Signed-off-by: Bryan Wu

leds: Include linux/of.h header

2013-10-22T17:57:34Z

'of_match_ptr' is defined in linux/of.h. Include it explicitly. Signed-off-by: Sachin Kamat Signed-off-by: Bryan Wu

leds: dac124s085: Remove redundant spi_set_drvdata

2013-10-22T17:57:34Z

Driver core sets driver data to NULL upon failure or remove. Signed-off-by: Sachin Kamat Cc: Guennadi Liakhovetski Signed-off-by: Bryan Wu

leds: lp55xx: enable setting default trigger

2013-10-22T17:57:34Z

This enables setting a default trigger on an LP55xx channel, either from platform data or device tree. This mechanism is identical to the mechanism for GPIO LEDs and references the common LEDs device tree bindings.
