* drivers/leds/ledtrig-timer.c: fix broken sysfs delay handlingJohan Hovold2011-09-141-0/+2
| | | | | | | | | | | | | | | Fix regression introduced by commit 5ada28bf7675 ("led-class: always implement blinking") which broke sysfs delay handling by not storing the updated value. Consequently it was only possible to set one of the delays through the sysfs interface as the other delay was automatically restored to it's default value. Reading the parameters always gave the defaults.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver handles the variants pca9530-pca9533, so it chose the name "pca953x". However, there is a gpio driver which decided on the same name. As a result, those two can't be loaded at the same time. Add a subsystem prefix to make the driver name unique. Device matching will not suffer, because both are I2C drivers which match using a i2c_device_id-table which is not altered.

* leds: support automatic start of blinking with ledtrig-timerEsben Haabendal2011-05-253-1/+12
| | | | | | | | | | | | | | | | | | | By setting initial values blink_delay_on and blink_delay_off in a led_classdev struct, this change starts the blinking when the led is initialized. With this patch, you can initialize blink_delay_on and blink_delay_off in led_classdev with default_trigger set to "timer", and the led will start up blinking. The current ledtrig-timer implementation ignores any initial blink_delay_on/blink_delay_off settings, and requires setting blink_delay_on/blink_delay_off (typically from userspace) before the led blinks.

Note that mfd-core no longer makes a copy of platform_data, but the mc13xxx-core driver creates the pdata structures on the stack. In order to get around that, the various ARM mach types that set the pdata have been changed to hold the variable in static (global) memory. Also note that __initdata references in aforementioned pdata structs have been dropped. Signed-off-by: Andres Salomon <dilinger@queued.net> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | Extend the LED backlight tirgger driver with an option that allows for inverting the trigger output polarity. With the invertion option provided, I (ab)use the backlight trigger for driving a LED that indicates LCD display blank condtition on my Amstrad Delta videophone. Since the machine has no dedicated power LED, it was not possible to distinguish if the display was blanked, or the machine was turned off, without touching it. The invert sysfs control is patterned after a similiar function of the GPIO trigger driver.

* leds-lp5521: modify the way of setting led device nameArun Murthy2011-01-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Currently the led device name is fetched from the device_type in I2C_BOARD_INFO which comes from the platform data. This name is in turn used to create an entry in sysfs. If there exists two or more lp5521 on a particular platform, the device_type in I2C_BOARD_INFO has to be the same, else lp5521 driver probe wont be called and if used so, results in run time warning "cannot create sysfs with same name" and hence a failure. The name that is used to create sysfs entry is to be passed by the struct led_platform_data. Hence adding an element of type const char * and change in lp5521 driver to use this name in creating the led device if present else use the name obtained by I2C_BOARD_INFO.
