| | | | | | | | | | | LP5521 is a three channel led driver with support for hardware accelerated patterns (currently used via lp5521-only sysfs interface). Currently, it's used on n810 device.

* leds: just ignore invalid GPIOs in leds-gpioDavid Brownell2009-04-06
| | | | | | | | | | | | | | | Sometimes it's awkward to make sure that the array in the platform_data handed to the leds-gpio driver has only valid data ... some leds may not be always available, and coping with that currently requires patching or rebuilding the array. This patch fixes that by making it be OK to pass an invalid GPIO (such as "-EINVAL") ... such table entries are skipped.

* leds: move h1940-leds's probe function to .devinit.textUwe Kleine-König2009-04-06
| | | | | | | | | | | | | | | A pointer to h1940leds_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

* leds: add BD2802GU LED driverKim Kyuwon2009-04-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Balbi2009-04-06
| | | | | | | | | | | | | | | | | | | | | 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 Piepho2009-04-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* lis3lv02d: merge with leds hp diskEric Piel2009-01-15
| | | | | | | | | | | | | | | | Move the second part of the HP laptop disk protection functionality (a red led) to the same driver. 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. Also make it requires the led class to compile and update the Kconfig text.

* leds: Add WM8350 LED driverMark Brown2009-01-08
| | | | | | | | | | | | | | | | | | | 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.
