Scott James Remnant 14f8d3ff31 applicom: Auto-load applicom module when device opened.
The applicom module is missing the char-major-10-157 alias that would
cause it to be auto-loaded when a device of that type is opened.  This
patch adds the alias.

Mario Schwalbe c78a628849 backlight: Add support for MacBook 5, MacBook Air 2, and MacBook Pro 5
This patch adds support for the new Apple models incorporating an Nvidia
chipset.  Apple still uses the same protocol as on older models, but the
registers moved to a different address. To do this, two sets of functions
are added for the Intel/Nvidia chipset models and passed by the DMI_MATCH
function.

The initial code has been contributed by Hu Gang <hugang@soulinfo.com>.

The driver is known to work on MacBook Pro 3, MacBook Pro 4 and MacBook
Pro 5.

Its known to work with limitations on MacBook 5 / MacBook Air 2. Changing
brightness within X doesn't work, if using Nvidia's proprietary graphics
driver with no known fix at present. Changing brightness on a text console
or using the open-source driver does work.

MacBook Pro 5 has a known bug where the initial brightness after bootup is
the last recently used brightness (in Mac OSX), while the firmware reports
maximum. Impossible to fix.

David Brownell d379ee8acd leds: just ignore invalid GPIOs in leds-gpio
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.

Uwe Kleine-König b0edba7ef8 leds: move h1940-leds's probe function to .devinit.text
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.

Kim Kyuwon 0b56129be7 leds: add BD2802GU LED driver
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

Felipe Balbi 17354bfe85 leds: Add gpio-led trigger
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.

Phil Sutter ac67e23bed leds: Add rb532 LED driver for the User LED
Mikrotik built six LEDs into the Routerboard 532, from which one is
destined for custom use, the so called "User LED". This patch adds a
driver for it, based on the LEDs class.

Luotao Fu 41c42ff5db leds: simple driver for pwm driven LEDs
Add a simple driver for pwm driver LEDs.  pwm_id and period can be defined
in board file.  It is developed for pxa, however it is probably generic
enough to be used on other platforms with pwm.
