2012-05-29leds: add LM3533 LED driverJohan Hovold
Add sub-driver for the LEDs on National Semiconductor / TI LM3533 lighting power chips. The chip provides 256 brightness levels, hardware accelerated blinking as well as ambient-light-sensor and pwm input control.

2012-05-29leds: add new transient trigger for one shot timer activationShuah Khan
The leds timer trigger does not currently have an interface to activate a one shot timer. The current support allows for setting two timers, one for specifying how long a state to be on, and the second for how long the state to be off. The delay_on value specifies the time period an LED should stay in on state, followed by a delay_off value that specifies how long the LED should stay in off state. The on and off cycle repeats until the trigger gets deactivated. There is no provision for one time activation to implement features that require an on or off state to be held just once and then stay in the original state forever. Without one shot timer interface, user space can still use timer trigger to set a timer to hold a state, however when user space application crashes or goes away without deactivating the timer, the hardware will be left in that state permanently. As a specific example of this use-case, let's look at vibrate feature on phones. Vibrate function on phones is implemented using PWM pins on SoC or PMIC. There is a need to activate one shot timer to control the vibrate feature, to prevent user space crashes leaving the phone in vibrate mode permanently causing the battery to drain. This trigger exports three properties, activate, state, and duration When transient trigger is activated these properties are set to default values. - duration allows setting timer value in msecs. The initial value is 0. - activate allows activating and deactivating the timer specified by duration as needed. The initial and default value is 0. This will allow duration to be set after trigger activation. - state allows user to specify a transient state to be held for the specified duration.

2011-10-31leds: Renesas TPU LED driverMagnus Damm
Add V2 of the LED driver for a single timer channel for the TPU hardware block commonly found in Renesas SoCs. The driver has been written with optimal Power Management in mind, so to save power the LED is driven as a regular GPIO pin in case of maximum brightness and power off which allows the TPU hardware to be idle and which in turn allows the clocks to be stopped and the power domain to be turned off transparently. Any other brightness level requires use of the TPU hardware in PWM mode. TPU hardware device clocks and power are managed through Runtime PM. System suspend and resume is known to be working - during suspend the LED is set to off by the generic LED code. The TPU hardware timer is equipeed with a 16-bit counter together with an up-to-divide-by-64 prescaler which makes the hardware suitable for brightness control. Hardware blink is unsupported. The LED PWM waveform has been verified with a Fluke 123 Scope meter on a sh7372 Mackerel board. Tested with experimental sh7372 A3SP power domain patches. Platform device bind/unbind tested ok. V2 has been tested on the DS2 LED of the sh73a0-based AG5EVM.

2011-09-21x86: geode: New PCEngines Alix system driverEd Wildgoose
This new driver replaces the old PCEngines Alix 2/3 LED driver with a new driver that controls the LEDs through the leds-gpio driver. The old driver accessed GPIOs directly, which created a conflict and prevented also loading the cs5535-gpio driver to read other GPIOs on the Alix board. With this new driver, we hook into leds-gpio which in turn uses GPIO to control the LEDs and therefore it's possible to control both the LEDs and access onboard GPIOs Driver is moved to platform/geode as requested by Grant and any other geode initialisation modules should move here also This driver is inspired by leds-net5501.c by Alessandro Zummo. Ideally, leds-net5501.c should also be moved to platform/geode. Additionally the driver relies on parts of the patch: 7f131cf3ed ("leds: leds-alix2c - take port address from MSR) by Daniel Mack to perform detection of the Alix board.

The gpio will registers all chip pins but will filter on gpio_request.

2010-12-02leds: fix up dependenciesJohannes Berg
It's not useful to build LED triggers when there's no LEDs that can be triggered by them. Therefore, fix up the dependencies so that this cannot happen, and fix a few users that select triggers to depend on LEDS_CLASS as well (there is also one user that also selects LEDS_CLASS, which is OK).

2010-11-12led-class: always implement blinkingJohannes Berg
Currently, blinking LEDs can be awkward because it is not guaranteed that all LEDs implement blinking. The trigger that wants it to blink then needs to implement its own timer solution. Rather than require that, add led_blink_set() API that triggers can use. This function will attempt to use hw blinking, but if that fails implements a timer for it. To stop blinking again, brightness_set() also needs to be wrapped into API that will stop the software blink. As a result of this, the timer trigger becomes a very trivial one, and hopefully we can finally see triggers using blinking as well because it's always easy to use.

The ALIX2 LED driver and the CS5535 GPIO drivers share the same I/O range which causes a conflict if they're both enabled. Fix this for now by adding Kconfig dependencies. While at it, also drop the EXPERIMENTAL flag, as the code has been around for awhile already. Note that this is a hack. At some point, a real platform support for this board should be added which handles the LEDs via the leds-gpio driver.

I don't have any need for brightness control, and its code is *completely* separate from the on/off controls implemented here. If anyone else wants it, I'd be happy to look into adding it, but I don't care enough for now. Except for the probe routines, I rewrote most of it. I also Note that I don't have any hardware documentation except for the original driver.
