leds: move LEDS_GPIO_REGISTER out of menuconfig NEW_LEDS Commit 4440673a95e6 ("leds: provide helper to register "leds-gpio" devices") broke the display of the NEW_LEDS menu as it didn't depend on NEW_LEDS and so made "LED drivers" and "LED Triggers" appear at the same level as "LED Support" instead of below it as it was before 4440673a. Moving LEDS_GPIO_REGISTER out of the menuconfig NEW_LEDS fixes this unintended side effect.

This option provides the function gpio_led_register_device.
As this function is used by arch code it must not be compiled as a
module.

Say Y to enable Linux LED support. This allows control of supported
LEDs from both userspace and optionally, by kernel events (triggers).
This is not related to standard keyboard LEDs which are controlled
via the input system.

PWM LED driver This is a LED driver using the PWM on newer SOCs from Atmel; brightness is controlled by changing the PWM duty cycle. So for example if you've set up two leds labeled "pwm0" and "pwm1": echo 0 > /sys/class/leds/pwm2/brightness # off (0%) echo 80 > /sys/class/leds/pwm2/brightness echo 255 > /sys/class/leds/pwm2/brightness # on (100%) Note that "brightness" here isn't linear; maybe that should change. Going from 4 to 8 probably doubles perceived brightness, while 244 to 248 is imperceptible. This is mostly intended to be a simple example of PWM, although it's realistic since LCD backlights are often driven with PWM to conserve battery power (and offer brightness options).

[PATCH] PCEngines WRAP LED Support A driver for the PCEngines WRAP boards (http://www.pcengines.ch), which are very similar to the Soekris net4801 (same NS SC1100 geode reference design). The LEDs on the WRAP are on different GPIO lines and I have modified and copied the net48xx error led support for this. It also includes support for an "extra" led (in addition to error). The three LEDs on the WRAP are at GPIO lines 2,3,18 (WRAP LEDs from left to right). This driver gives access to the second and third LEDs by twiddling GPIO lines 3 & 18. Because these boards are so similar to the net48xx, I basically sed-ed that driver to form the basis for leds-wrap.c. The only changes from leds-net48xx.c are: - #define WRAP_EXTRA_LED_GPIO - name changes - duplicate relevant sections to provide support for the "extra" led - reverse the various *_led_set values. The WRAP is "backwards" from the net48xx, and these needed to be updated for that.

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.

This option enables support for the LEDs on the HTC ASIC3. The HTC
ASIC3 LED GPIOs are inputs, not outputs, thus the leds-gpio driver
cannot be used. This driver supports hardware blinking with an on+off
period from 62ms to 125s. Say Y to enable LEDs on the HP iPAQ hx4700.
leds: Renesas TPU LED driver 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.

This option enables build of the LED TPU platform driver,

The driver controls the GPIO pin connected to the LED via

a pin that can be driven in both GPIO mode and using TPU
pin function. The latter to support brightness control.
Brightness control is supported but hardware blinking is not.
