2008-04-29Remove duplicated unlikely() in IS_ERR()Hirofumi Nakagawa1-1/+1
Some drivers have duplicated unlikely() macros. IS_ERR() already has unlikely() in itself. This patch cleans up such pointless code.

2008-04-24leds: Add new driver for the LEDs on the Freecom FSG-3Rod Whitby3-0/+268
The LEDs on the Freecom FSG-3 are connected to an external memory-mapped latch on the ixp4xx expansion bus, and therefore cannot be supported by any of the existing LEDs drivers. Signed-off-by: Rod Whitby <[email protected]> Signed-off-by: Richard Purdie <[email protected]>
2008-04-24leds: Add support to leds with readable statusHenrique de Moraes Holschuh1-0/+9
Some led hardware allows drivers to query the led state, and this patch adds a hook to let the led class take advantage of that information when available. Without this functionality, when access to the led hardware is not exclusive (i.e. firmware or hardware might change its state behind the kernel's back), reality goes out of sync with the led class' idea of what the led is doing, which is annoying at best. Behaviour for drivers that do not or cannot read the led status is unchanged. Signed-off-by: Henrique de Moraes Holschuh <[email protected]> Signed-off-by: Richard Purdie <[email protected]>

Break the lines which were more than 80 characters into more lines; replace SPACEs with TABs; correct ident at switch-case; change character encoding from ISO-8859-2 to UTF-8.

2008-04-23leds: Do not guard NEW_LEDS with HAS_IOMEMDavid S. Miller1-1/+0
The LEDS infrastructure itself does not require anything that a platform dependant upon HAS_IOMEM. The individual drivers do, but they are properly guarded with the necessary platform dependencies. One can even imagine a hypervisor based LED driver that a platform without HAS_IOMEM might have. Signed-off-by: David S. Miller <[email protected]>

2008-04-19PM: Remove destroy_suspended_device()Rafael J. Wysocki1-8/+3
After 2.6.24 there was a plan to make the PM core acquire all device semaphores during a suspend/hibernation to protect itself from concurrent operations involving device objects. That proved to be too heavy-handed and we found a better way to achieve the goal, but before it happened, we had introduced the functions device_pm_schedule_removal() and destroy_suspended_device() to allow drivers to "safely" destroy a suspended device and we had adapted some drivers to use them. Now that these functions are no longer necessary, it seems reasonable to remove them and modify their users to use the normal device unregistration instead. Signed-off-by: Rafael J.

2008-02-08PWM LED driverDavid Brownell3-0/+165
This is a LED driver using the PWM on newer SOCs from Atmel; brightness is controlled by changing the PWM duty cycle. So for example if you've set up two leds labeled "pwm0" and "pwm1": echo 0 > /sys/class/leds/pwm2/brightness # off (0%) echo 80 > /sys/class/leds/pwm2/brightness echo 255 > /sys/class/leds/pwm2/brightness # on (100%) Note that "brightness" here isn't linear; maybe that should change. Going from 4 to 8 probably doubles perceived brightness, while 244 to 248 is imperceptible. This is mostly intended to be a simple example of PWM, although it's realistic since LCD backlights are often driven with PWM to conserve battery power (and offer brightness options).

2008-02-07leds: Fix led-gpio active_low default brightnessRaphael Assenat1-1/+1
When gpio_direction_output() is called, led_dat->active_low is used as default value.

2007-11-05leds: bugfixes for leds-gpioDavid Brownell1-9/+11
Three bugfixes to the leds-gpio driver, plus minor whitespace tweaks: - Do the INIT_WORK() before registering each LED, so if its trigger becomes immediately active it can schedule work without oopsing.. - Use normal registration, not platform_driver_probe(), so that devices appearing "late" (hotplug type) can still be bound. - Mark the driver remove code as "__devexit", preventing oopses when the underlying device is removed. These issues came up when using this driver with some GPIO expanders living on serial busses, which act unlike "normal" platform devices: they can appear and vanish along with the serial bus driver.
