2017-08-14leds: pca955x: add GPIO supportCédric Le Goater1-0/+11
The PCA955x family of chips are I2C LED blinkers whose pins not used to control LEDs can be used as general purpose I/Os (GPIOs). The following adds such a support by defining different operation modes for the pins (See bindings documentation for more details). The pca955x driver is then extended with a gpio_chip when some of pins are operating as GPIOs. The default operating mode is to behave as a LED. The GPIO support is conditioned by CONFIG_LEDS_PCA955X_GPIO.

In ACPI world any ID should be carefully chosen and registered officially. The discussion [1] as I read it gets to wilful assignment an ID for non-existing real DSDT example. Rafael already told [2] how this device would be enumerated using compatible string.

Source code is moved along with the relevant Kconfig and Makefile entries, with some minor modifications: - Kconfig option is renamed from CONFIG_LEDS_DELL_NETBOOKS to CONFIG_DELL_WMI_LED, - the X86 Kconfig dependency is removed as the whole drivers/platform/x86 menu depends on it, so there is no need to duplicate it, - the name of the module's source file is removed from the header comment to avoid the need to update it in the future.

2017-01-29leds: class: Add new optional brightness_hw_changed attributeHans de Goede1-0/+9
Some LEDs may have their brightness level changed autonomously (outside of kernel control) by hardware / firmware. This commit adds support for an optional brightness_hw_changed attribute to signal such changes to userspace (if a driver can detect them): What: /sys/class/leds/<led>/brightness_hw_changed Date: January 2017 KernelVersion: 4.11 Description: Last hardware set brightness level for this LED. Some LEDs may be changed autonomously by hardware/firmware. Only LEDs where this happens and the driver can detect this, will have this file. This file supports poll() to detect when the hardware changes the brightness. Reading this file will return the last brightness level set by the hardware, this may be different from the current brightness. Drivers which want to support this, simply add LED_BRIGHT_HW_CHANGED to their flags field and call led_classdev_notify_brightness_hw_changed() with the hardware set brightness when they detect a hardware / firmware triggered brightness change.

This driver creates a userspace leds driver similar to uinput. New LEDs are created by opening /dev/uleds and writing a uleds_user_dev struct. A new LED class device is registered with the name given in the struct. Reading will return a single byte that is the current brightness. The poll() syscall is also supported. It will be triggered whenever the brightness changes. Closing the file handle to /dev/uleds will remove the leds class device.

2016-11-21mfd: qcom-pm8xxx: Clean up PM8XXX namespaceLinus Walleij1-1/+1
The Kconfig and file naming for the PM8xxx driver is totally confusing: - Kconfig options MFD_PM8XXX and MFD_PM8921_CORE, some in-kernel users depending on or selecting either at random. - A driver file named pm8921-core.c even if it is indeed used by the whole PM8xxx family of chips. - An irqchip named pm8xxx since it was (I guess) realized that the driver was generic for all pm8xxx PMICs. As I may want to add support for PM8901 this is starting to get really messy. Fix this situation by: - Remove the MFD_PM8921_CORE symbol and rely solely on MFD_PM8XXX and convert all users, including LEDs Kconfig and ARM defconfigs for qcom and multi_v7 to use that single symbol. - Renaming the driver to qcom-pm8xxx.c to fit along the two other qcom* prefixed drivers. - Rename functions withing the driver from 8921 to 8xxx to indicate it is generic. - Just drop the =m config from the pxa_defconfig, I have no clue why it is even there, it is not a Qualcomm platform. (Possibly older Kconfig noise from saveconfig.)

This is a driver for the Integrated Silicon Solution Inc. LED driver chips series IS31FL319x. They can drive 1, 3, 6 or up to 9 LEDs. Each LED is individually controllable in brightness (through pwm) in 256 steps so that RGB LEDs can show any of ca. 16 Mio colors. The maximum current of the LEDs can be programmed and limited to 5 .. 40mA through a device tree property. The chip is connected through I2C and can have one of 4 addresses in the range 0x64 .. 0x67 depending on how the AD pin is connected. The address is defined by the reg property as usual. The chip also has a shutdown input which could be connected to a GPIO, but this driver uses software shutdown if all LEDs are inactivated. The chip also has breathing and audio features which are not fully supported by this driver. Tested-on: OMAP5 based Pyra handheld prototype. Signed-off-by: H.

2016-03-14leds: Add driver for the ISSI IS31FL32xx family of LED controllersDavid Rivshin1-0/+8
The IS31FL32xx family of LED controllers are I2C devices with multiple constant-current channels, each with independent 256-level PWM control. Datasheets: http://www.issi.com/US/product-analog-fxled-driver.shtml This has been tested on the IS31FL3236 and IS31FL3216, on an ARM (TI am335x) platform. The programming paradigm of these devices is similar in the following ways: - All registers are 8 bit - All LED control registers are write-only - Each LED channel has a PWM register (0-255) - PWM register writes are shadowed until an Update register is poked - All have a concept of Software Shutdown, which disables output However, there are some differences in devices: - 3236/3235 have a separate Control register for each LED, (3218/3216 pack the enable bits into fewer registers) - 3236/3235 have a per-channel current divisor setting - 3236/3235 have a Global Control register that can turn off all LEDs - 3216 is unique in a number of ways - OUT9-OUT16 can be configured as GPIOs instead of LED controls - LEDs can be programmed with an 8-frame animation, with programmable delay between frames - LEDs can be modulated by an input audio signal - Max output current can be adjusted from 1/4 to 2x globally - Has a Configuration register instead of a Shutdown register This driver currently only supports the base PWM control function of these devices. The following features of these devices are not implemented, although it should be possible to add them in the future: - All devices are capable of going into a lower-power "software shutdown" mode. - The is31fl3236 and is31fl3235 can reduce the max output current per-channel with a divisor of 1, 2, 3, or 4. - The is31fl3216 can use some LED channels as GPIOs instead. - The is31fl3216 can animate LEDs in hardware. - The is31fl3216 can modulate LEDs according to an audio input. - The is31fl3216 can reduce/increase max output current globally.

2015-09-17leds:lp55xx: Correct Kconfig dependency for f/w user helperTakashi Iwai1-1/+1
The commit [b67893206fc0: leds:lp55xx: fix firmware loading error] tries to address the firmware file handling with user helper, but it sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK. Since the wrong option was enabled, the system got a regression -- it suffers from the unexpected long delays for non-present firmware files. This patch corrects the Kconfig dependency to the right one, CONFIG_FW_LOADER_USER_HELPER. This doesn't change the fallback behavior but only enables UMH when needed.

2015-08-20leds/powernv: Add driver for PowerNV platformVasant Hegde1-0/+11
This patch implements LED driver for PowerNV platform using the existing generic LED class framework. PowerNV platform has below type of LEDs: - System attention Indicates there is a problem with the system that needs attention. - Identify Helps the user locate/identify a particular FRU or resource in the system. - Fault Indicates there is a problem with the FRU or resource at the location with which the indicator is associated. We register classdev structures for all individual LEDs detected on the system through LED specific device tree nodes. Device tree nodes specify what all kind of LEDs present on the same location code. It registers LED classdev structure for each of them. All the system LEDs can be found in the same regular path /sys/class/leds/. We don't use LED colors. We use LED node and led-types property to form LED classdev. Our LEDs have names in this format. <location_code>:<attention|identify|fault> Any positive brightness value would turn on the LED and a zero value would turn off the LED. The driver will return LED_FULL (255) for any turned on LED and LED_OFF (0) for any turned off LED. The platform level implementation of LED get and set state has been achieved through OPAL calls. These calls are made available for the driver by exporting from architecture specific codes.

2015-06-29leds:lp55xx: fix firmware loading errorMilo Kim1-0/+1
LP55xx driver uses not firmware file but raw data to load program through the firmware interface.(Documents/leds/leds-lp55xx.txt) For example, here is how to run blinking green channel pattern. (The second engine is seleted and MUX is mapped to 'RGB' mode) echo 2 > /sys/bus/i2c/devices/xxxx/select_engine echo "RGB" > /sys/bus/i2c/devices/xxxx/engine_mux echo 1 > /sys/class/firmware/lp5562/loading echo "4000600040FF6000" > /sys/class/firmware/lp5562/data echo 0 > /sys/class/firmware/lp5562/loading echo 1 > /sys/bus/i2c/devices/xxxx/run_engine However, '/sys/class/firmware/<device name>' is not created after the firmware loader user helper was introduced. This feature is used in the case below. As soon as the firmware download is requested by the driver, firmware class subsystem tries to find the binary file. If it gets failed, then it just falls back to user helper to load raw data manually. Here, you can see the device file under /sys/class/firmware/. To make it happen, LP55xx driver requires two configurations. 1. Enable CONFIG_FW_LOADER_USER_HELPER_FALLBACK in Kconfig 2. Set option, 'FW_OPT_USERHELPER' on requesting the firmware data. It means the second option should be 'false' in request_firmware_nowait(). This option enables to load firmware data manually by calling fw_load_from_user_helper().

2015-06-11Input: export LEDs as class devices in sysfsSamuel Thibault1-3/+0
This change creates a new input handler called "leds" that exports LEDs on input devices as standard LED class devices in sysfs and allows controlling their state via sysfs or via any of the standard LED triggers. This allows to re-purpose and reassign LDEs on the keyboards to represent states other than the standard keyboard states (CapsLock, NumLock, etc). The old API of controlling input LEDs by writing into /dev/input/eventX devices is still present and will take precedence over accessing via LEDs subsystem (i.e. it may override state set by a trigger). If input device is "grabbed" then requests coming through LED subsystem will be ignored.
