* LEDS: fix race in device_createGreg Kroah-Hartman2008-05-201-4/+2
| | | | | | | | | | | | | | | There is a race from when a device is created with device_create() and then the drvdata is set with a call to dev_set_drvdata() in which a sysfs file could be open, yet the drvdata will be NULL, causing all sorts of bad things to happen. This patch fixes the problem by using the new function, device_create_drvdata().

| | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers have duplicated unlikely() macros. IS_ERR() already has unlikely() in itself. This patch cleans up such pointless code.

* leds: Add support to leds with readable statusHenrique de Moraes Holschuh2008-04-241-0/+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 <hmh@hmh.eng.br> Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | The LEDS infrastructure itself does not require anything that a platform dependant upon HAS_IOMEM.

| * | PM: Remove destroy_suspended_device()Rafael J. Wysocki2008-04-191-8/+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.

* PWM LED driverDavid Brownell2008-02-083-0/+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).

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.
