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.

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.

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. Signed-off-by:

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:

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.

Add bindings to support LEDs defined as of_platform devices in addition to the existing bindings for platform devices. 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. Signed-off-by:

By default, CFQ will anticipate more IO from a given io context if the previously completed IO was sync. This used to be fine, since the only sync IO was reads and O_DIRECT writes. But with more "normal" sync writes being used now, we don't want to anticipate for those. Add a bio/request flag that informs the IO scheduler that this is a sync request that we should not idle for. Introduce WRITE_ODIRECT specifically for O_DIRECT writes, and make sure that the other sync writes set this flag. Signed-off-by:
