Merge tag 'leds_for_4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED updates from Jacek Anaszewski:
"This time we're removing more than adding:
Removed drivers:
leds-versatile:
- all users of the Versatile LED driver are deleted and replaced
with the very generic leds-syscon
leds-sead3:
- SEAD3 is using the generic leds-syscon & regmap based
register-bit-led driver
LED class drivers improvements:
ledtrig-gpio:
- use threaded IRQ, which both simplifies the code because we can
drop the workqueue indirection, and it enables using the trigger
for GPIOs that work with threaded IRQs themselves
- refresh LED state after GPIO change since the new GPIO may have
a different state than the old one
leds-lp55xx:
- make various arrays static const
leds-pca963x:
- add bindings to invert polarity"

leds: pca963x: Add bindings to invert polarity
Some LEDs can be related to a specific device(s) described in the DT.
This property allows specifying such relations. E.g. USB LED should
usually be used to indicate some USB port(s) state.
Please note this binding is designed to be generic and not influenced by
any operating system design. Linux developers may find "trigger" part a
bit confusing since in Linux triggers are separated drivers. It
shouldn't define the binding though (we shouldn't add an extra level of
indirection).

* tag 'backlight-for-linus-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/backlight:
backlight: lp855x: Add enable regulator
The LP8556 datasheet describes an EN/VDDIO input, which serves "both as
a chip enable and as a power supply reference for PWM, SDA, and SCL
inputs." The LP8556 that I'm testing doesn't respond properly if I try
to talk I2C to it too quickly after enabling VDDIO, and the LP8555
datasheet mentions a t_RESPONSE delay of up to 1 millisecond.
Support this EN/VDDIO by adding a regulator property to the binding;
enabling this regulator at probe time; and sleeping for 1 to 2ms, if the
EN/VDDIO regulator was provided.

On the board n090401 (Seagate NAS 4-Bay), the LED mode mapping (GPIO
values to LED mode) is different from the one used on other boards
supported by the leds-ns2 driver.
With this patch the hardcoded mapping is removed from leds-ns2. Now,
it must be defined either in the platform data (if an old-fashion board
setup file is used) or in the DT node. In order to allow the later, this
patch also introduces a modes-map property for the leds-ns2 DT binding.

1. Since max-microamp property has had no users so far, then rename
it to more descriptive led-max-microamp.
2. Since flash-timeout-us property has had no users so far, then rename
it to more accurate flash-max-timeout-us.
3. Describe led-max-microamp property as mandatory for specific board
configurations.
4. Make flash-max-microamp and flash-max-timeout-us properties mandatory
for devices with configurable flash current and flash timeout settings
respectively.

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.
