leds: Mark GPIO LED trigger broken
The GPIO LED trigger exposes a userspace ABI where a user can echo a GPIO number from the global GPIO numberspace into a file that will trigger a certain LED when active.
This is problematic because the global GPIO numberspace is inherently instable. The trigger came about at a time when systems had one GPIO controller that defined hard-wired GPIOs numbered 0..N and this number space was stable.
We have since moved to dynamic allocation of GPIO numbers and there is no real guarantee that a GPIO number will stay consistent even across a reboot: consider a USB attached GPIO controller for example. Or two. Or the effect of probe order after adding -EPROBE_DEFER to the kernel.
The trigger was added to support keypad LEDs on the Nokia n810 from the GPIO event when a user slides up/down the keypad. This is arch/arm/boot/dts/omap2420-n810.dts. A userspace script is needed to activate the trigger. This will be broken unless the script was updated recently since the OMAP GPIO controller now uses dynamic GPIO number allocations.
I want to know that this trigger has active users that cannot live without it if we are to continue to support it.
Option if this is really needed: I can develop a new trigger that can associate GPIOs with LEDs as triggers using device tree, which should also remove the use of userspace custom scripts to achieve this and be much more trustworthy, if someone with the Nokia n810 or a device with a similar need is willing to test it.

leds: trigger: Disable CPU trigger on PREEMPT_RT
The CPU trigger is invoked on ARM from CPU-idle. That trigger later invokes led_trigger_event() which may invoke the callback of the actual driver. That driver can acquire a spinlock_t which is okay on kernel without PREEMPT_RT. On a PREEMPT_RT enabled kernel this lock is turned into a sleeping lock and must not be acquired with disabled interrupts.
Disable the CPU trigger on PREEMPT_RT.

leds: trigger: Introduce audio mute LED trigger
This patch adds a new LED trigger for coupling the audio mixer change with the LED on laptops or other devices. Currently there are two trigger types, "audio-mute" and "audio-micmute".
The audio driver triggers the LED brightness change via ledtrig_audio_set() call with the proper type (either mute or mic-mute). OTOH, the consumers may call ledtrig_audio_get() for the initial brightness value that may have been set by the audio driver beforehand.
This new stuff will be used by HD-audio codec driver and some platform drivers (thinkpad_acpi and dell-laptop, also upcoming huawei-wmi).

leds: ledtrig-activity: Add a system activity LED trigger
The "activity" trigger was inspired by the heartbeat one, but aims at providing instant indication of the immediate CPU usage. Under idle condition, it flashes 10ms every second. At 100% usage, it flashes 90ms every 100ms. The blinking frequency increases from 1 to 10 Hz until either the load is high enough to saturate one CPU core or 50% load is reached on a single-core system. Then past this point only the duty cycle increases from 10 to 90%.
This results in a very visible activity reporting allowing one to immediately tell whether a machine is under load or not, making it quite suitable to be used in clusters.

leds: convert IDE trigger to common disk trigger
This patch converts the IDE specific LED trigger to a generic disk activity LED trigger. The libata core is now a trigger source just like before the IDE disk driver. It's merely a replacement of the string ide by disk.
The patch is taken from http://dev.gentoo.org/~josejx/ata.patch and is widely used by any ibook/powerbook owners with great satisfaction. Likewise, it is very often used successfully on different ARM platforms.
Unlike the original patch, the existing 'ide-disk' trigger is still available for backward compatibility. That reduce the amount of patches in affected device trees out of the mainline kernel. For further development, the new name 'disk-activity' should be used.

leds: triggers: Allow to switch the trigger to "panic" on a kernel panic
This commit adds a new led_cdev flag LED_PANIC_INDICATOR, which allows to mark a specific LED to be switched to the "panic" trigger, on a kernel panic.
This is useful to allow the user to assign a regular trigger to a given LED, and still blink that LED on a kernel panic.

leds: trigger: Introduce a MTD (NAND/NOR) trigger
This commit introduces a MTD trigger for flash (NAND/NOR) device activity. The implementation is copied from IDE disk.
This trigger deprecates the "nand-disk" LED trigger, but for backwards compatibility, we still keep the "nand-disk" trigger around.
The motivation for deprecating the "nand-disk" LED trigger is that it only works for NAND drivers, whereas the "mtd" LED trigger is more generic (in fact, "nand-disk" currently only works for certain NAND drivers).

leds: trigger: Introduce a kernel panic LED trigger
This commit introduces a new LED trigger which allows to configure a LED to blink on a kernel panic (through panic_blink).
Notice that currently the Openmoko FreeRunner (GTA02) mach code sets panic_blink to blink a hard-coded LED. The new trigger is meant to introduce a generic mechanism to achieve this.

leds: Allow compile test of GPIO consumers if !GPIOLIB
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled.
Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.

Some LED devices support flash/torch functionality through the LED subsystem. This patch enables direct LED trigger controls by the driver. Flash on/off and torch on/off can be done simply by other driver space. Two trigger APIs are added, ledtrig_flash_ctrl() and ledtrig_torch_ctrl().

leds: trigger: Introduce audio mute LED trigger This patch adds a new LED trigger for coupling the audio mixer change with the LED on laptops or other devices. Currently there are two trigger types, "audio-mute" and "audio-micmute". The audio driver triggers the LED brightness change via ledtrig_audio_set() call with the proper type (either mute or mic-mute). OTOH, the consumers may call ledtrig_audio_get() for the initial brightness value that may have been set by the audio driver beforehand. This new stuff will be used by HD-audio codec driver and some platform drivers (thinkpad_acpi and dell-laptop, also upcoming huawei-wmi).
