Subject: [PATCH] [neo1973 leds] Move from mutex to spinlock because we may not use mutexes The led triggers may call set_brightness from atomic contexts. As mutex_lock calls might_sleep and sleeping is not allowed in atomic contexts we have to switch to spinlocks here. Signed-Off-By: Holger Freyther <zecke@openmoko.org>
2008-11-19[neo] Every access to GPIO bank B has to go through the shadow codeHolger Freyther
- Any setting of any PIN on bank B will undo the LED setting. Introduce neo1973_gpb_set_pin to set the PIN in a way not losing the LED or any other shadowed setting. - Update users of GPBXY for gta01 and gta02. Signed-Off-By: Holger Freyther <zecke@openmoko.org>
2008-11-19[led] Misc fixes in the driver codeHolger Freyther
to_bundle returned the wrong data. The platform_device is the parent of the class_device used by the LED device class. Return the correct class. num_leds was not set to the correct number of registered LEDs. All loops using num_leds (e.g. module unloading) were not executed at all. On removal of the module disable all LEDs. Signed-Off-By: Holger Freyther <zecke@openmoko.org>
2008-11-19[leds] We would enable PWM for all four timers, disable it for all four as wellHolger Freyther
Currently we do not use the PWM code to drive the LEDS. We have enabled the PWM for four timer sources but disable it only for three, fix that up. Signed-Off-By: Holger Freyther <zecke@openmoko.org>
