* leds: Renesas TPU LED driverMagnus Damm2011-11-011-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* led-class: always implement blinkingJohannes Berg2010-11-121-1/+1
| | | | | | | | | | | | | | | | | | | | 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.

* leds: add BD2802GU LED driverKim Kyuwon2009-04-061-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | ROHM BD2802GU is a RGB LED controller attached to i2c bus and specifically engineered for decoration purposes. This RGB controller incorporates lighting patterns and illuminates. This driver is designed to minimize power consumption, so when there is no emitting LED, it enters to reset state. And because the BD2802GU has lots of features that can't be covered by the current LED framework, it provides Advanced Configuration Function(ADF) mode, so that user applications can set registers of BD2802GU directly. Here are basic usage examples : ; to turn on LED (not blink) $ echo 1 > /sys/class/leds/led1_R/brightness ; to blink LED $ echo timer > /sys/class/leds/led1_R/trigger $ echo 1 > /sys/class/leds/led1_R/delay_on $ echo 1 > /sys/class/leds/led1_R/delay_off ; to turn off LED $ echo 0 > /sys/class/leds/led1_R/brightness [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Kim Kyuwon <chammoru@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>

* leds: Add gpio-led triggerFelipe Balbi2009-04-061-0/+13
| | | | | | | | | | | | | | | | | | | | | The gpio led trigger will allow leds to be triggered by gpio events. When we give the led a gpio number, the trigger will request_irq() on that so we don't have to keep polling for gpio state. It's useful for usecases as n810's keypad leds that could be triggered by the gpio event generated when user slides up to show the keypad. We also provide means for userland to tell us what is the desired brightness for that special led when it goes on so userland could use information from ambient light sensors and not set led brightness too high if it's not necessary.

* leds: Add openfirmware platform device supportTrent Piepho2009-04-061-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add bindings to support LEDs defined as of_platform devices in addition to the existing bindings for platform devices. New options in Kconfig allow the platform binding code and/or the of_platform code to be turned on. The of_platform code is of course only available on archs that have OF support. The existing probe and remove methods are refactored to use new functions create_gpio_led(), to create and register one led, and delete_gpio_led(), to unregister and free one led. The new probe and remove methods for the of_platform driver can then share most of the common probe and remove code with the platform driver. The suspend and resume methods aren't shared, but they are very short. The actual led driving code is the same for LEDs created by either binding. The OF bindings are based on patch by Anton Vorontsov <avorontsov@ru.mvista.com>. They have been extended to allow multiple LEDs per device.

From a purely Linux developer's point of view, the led and the accelerometer have nothing related. However, they correspond to the same ACPI functionality, and so will always be used together, moreover as they share the same ACPI PNP alias, there is no other simple to allow to have same loaded at the same time if they are not in the same module.

* leds: Add WM8350 LED driverMark Brown2009-01-081-0/+7
| | | | | | | | | | | | | | | | | | | The voltage and current regulators on the WM8350 AudioPlus PMIC can be used in concert to provide a power efficient LED driver. This driver implements support for this within the standard LED class. Platform initialisation code should configure the LED hardware in the init callback provided by the WM8350 core driver. The callback should use wm8350_isink_set_flash(), wm8350_dcdc25_set_mode() and wm8350_dcdc_set_slot() to configure the operating parameters of the regulators for their hardware and then then use wm8350_register_led() to instantiate the LED driver. This driver was originally written by Liam Girdwood, though it has been extensively modified since then.
