* leds: leds-pca9532 - Drop unused module parametersJean Delvare2009-10-04
| | | | | | | | | | The I2C_CLIENT_INSMOD_1 macro is only useful for i2c drivers which implement device detection. The leds-pca9532 driver doesn't, so there is no point in calling it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WM831x devices feature two software controlled status LEDs with hardware assisted blinking. The device can also autonomously control the LEDs based on a selection of sources. This can be configured at boot time using either platform data or the chip OTP. A sysfs file in the style of that for triggers allowing the control source to be configured at run time. Triggers can't be used here since they can't depend on the implementation details of a specific LED type.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The serio ports on i8042 are not completely isolated; while we provide enough locking to ensure proper serialization when accessing control and data registers AUX and KBD ports can still have an effect on each other on PS/2 protocol level. The most prominent effect is that issuing a command for the device connected to one port may cause abort of the command currently executing by the device connected to another port. Since i8042 nor serio subsystem are not aware of the details of the PS/2 protocol (length of the commands and their replies and so on) the locking should be done on libps2 level by adding special handling when we see that we are dealing with serio port on i8042.

* leds: fix multiple requests and releases of IRQ for GPIO LED TriggerThadeu Lima de Souza Cascardo2009-08-26
| | | | | | | | | | | | | | | | | When setting the same GPIO number, multiple IRQ shared requests will be done without freing the previous request. It will also try to free a failed request or an already freed IRQ if 0 was written to the gpio file. All these oops and leaks were fixed with the following solution: keep the previous allocated GPIO (if any) still allocated in case the new request fails. The alternative solution would desallocate the previous allocated GPIO and set gpio as 0. Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@holoscopio.com> Signed-off-by: Samuel R. C.

* leds: Add options to have GPIO LEDs start on or keep their stateTrent Piepho2009-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There already is a "default-on" trigger but there are problems with it. For one, it's a inefficient way to do it and requires led trigger support to be compiled in. But the real reason is that is produces a glitch on the LED. The GPIO is allocate with the LED *off*, then *later* when the trigger runs it is turned back on. If the LED was already on via the GPIO's reset default or action of the firmware, this produces a glitch where the LED goes from on to off to on. While normally this is fast enough that it wouldn't be noticeable to a human observer, there are still serious problems. One is that there may be something else on the GPIO line, like a hardware alarm or watchdog, that is fast enough to notice the glitch. Another is that the kernel may panic before the LED is turned back on, thus hanging with the LED in the wrong state. This is not just speculation, but actually happened to me with an embedded system that has an LED which should turn off when the kernel finishes booting, which was left in the incorrect state due to a bug in the OF LED binding code. We also let GPIO LEDs get their initial value from whatever the current state of the GPIO line is. On some systems the LEDs are put into some state by the firmware or hardware before Linux boots, and it is desired to have them keep this state which is otherwise unknown to Linux. This requires that the underlying GPIO driver support reading the value of output GPIOs. Some drivers support this and some do not. The platform device binding gains a field in the platform data "default_state" that controls this. There are three constants defined to select from on, off, or keeping the current state. The OpenFirmware binding uses a property named "default-state" that can be set to "on", "off", or "keep". The default if the property isn't present is off.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.

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.

* leds: Add suspend/resume to the core classRichard Purdie2009-01-08
| | | | | | | Add suspend/resume to the core class and remove all the now unneeded code from various drivers. Originally the class code couldn't support suspend/resume but since class_device can there is no reason for each driver doing its own suspend/resume anymore.
* 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.
