395cf9691d doc: fix broken references
There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.

Fix these broken references, sometimes by dropping the irrelevant text
they were part of.

7a5caabd09 drivers/leds/ledtrig-timer.c: fix broken sysfs delay handling
Fix regression introduced by commit 5ada28bf76 ("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.

30cb35be6d drivers/leds/leds-pca9532.c: change driver name to be unique
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.

be5ce2f1c9 leds: move LEDS_GPIO_REGISTER out of menuconfig NEW_LEDS
Commit 4440673a95 ("leds: provide helper to register "leds-gpio"
devices") broke the display of the NEW_LEDS menu as it didn't depend on
NEW_LEDS and so made "LED drivers" and "LED Triggers" appear at the same
level as "LED Support" instead of below it as it was before 4440673a.

Moving LEDS_GPIO_REGISTER out of the menuconfig NEW_LEDS fixes this
unintended side effect.

4440673a95 leds: provide helper to register "leds-gpio" devices
This function makes a deep copy of the platform data to allow it to live
in init memory.  For a kernel that supports several machines and so
includes the definition for several leds-gpio devices this saves quite
some memory because all but one definition can be free'd after boot.

As the function is used by arch code it must be builtin and so cannot go
into leds-gpio.c.

Allow unused leds on pca9532 to be used as gpio.  The board I am working
on now has no less than 6 pca9532 chips.  One chips is used for only leds,
one has 14 leds and 2 gpio and the rest of the chips are gpio only.

There is also one board in mainline which could use this capabilty;
arch/arm/mach-iop32x/n2100.c
 232         {       .type = PCA9532_TYPE_NONE }, /* power OFF gpio */
 233         {       .type = PCA9532_TYPE_NONE }, /* reset gpio */

This patch defines a new pin type, PCA9532_TYPE_GPIO, and registers a
gpiochip if any pin has this type set.  The gpio will registers all chip
pins but will filter on gpio_request.

fff26f8141 leds: support automatic start of blinking with ledtrig-timer
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.

592ce31639 leds/leds-regulator.c: fix handling of already enabled regulators
Make the driver aware of the initial status of the regulator.

The leds-regulator driver was ignoring the initial status of the
regulator; this resulted in rdev->use_count being incremented to 2 after
calling regulator_led_set_value() in the .probe method when a regulator
was already enabled at insmod time, which made it impossible to ever
disable the regulator.

4ec1b54c4d mfd: mfd_cell is now implicitly available to mc13xxx drivers
The cell's platform_data is now accessed with a helper function;
change clients to use that, and remove the now-unused data_size.

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.

9f9455ae71 leds: add output inversion option to backlight trigger
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.

61a83932b8 leds-lp5521: modify the way of setting led device name
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.

Driver contained possibility for circular locking.

One lock is held by sysfs-core and another one by the driver itself.  This
happened when the driver created or removed sysfs entries dynamically.
There is no real need to do those operations.  Now all the sysfs entries
are created at probe and removed at removal.  Engine load sysfs entries
are now visible all the time.  However, access to the entries fails if the
engine is disabled or running.
