2009-04-06leds: Add rb532 LED driver for the User LEDPhil Sutter
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.

2009-04-06leds: Add suspend/resume state flags to leds-gpioRichard Purdie
Add an option to preserve LED state when suspending/resuming to the LED gpio driver. Based on a suggestion from Robert Jarzmik. Tested-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>
2009-04-06leds: simple driver for pwm driven LEDsLuotao Fu
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.

2009-04-06leds: allow led-drivers to use a variable range of brightness valuesGuennadi Liakhovetski
This patch allows drivers to override the default maximum brightness value of 255. We take care to preserve backwards-compatibility as much as possible, so that user-space ABI doesn't change for existing drivers. LED trigger code has also been updated to use the per-LED maximum.

2009-04-06leds: Add openfirmware platform device supportTrent Piepho
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.

2009-04-06[MTD] mtdpart: Make ecc_stats more realistic.Yauhen Kharuzhy
In the existing implementation, ecc_stats fields are incremented only by one, regardless of master mtd errors number.

2009-04-06[MTD] [NAND] FSL-UPM: Add wait flags to support board/chip specific delaysWolfgang Grandegger
The NAND flash on the TQM8548_BE modules requires a short delay after running the UPM pattern. The TQM8548_BE requires a further short delay after writing out a buffer. Normally the R/B pin should be checked, but it's not connected on the TQM8548_BE. The existing driver uses similar fixed delay points. To manage these extra delays in a more general way, I introduced the "fsl,ump-wait-flags" property allowing the board- specific driver to specify various types of extra delay.

2009-04-06md/raid1 - don't assume newly allocated bvecs are initialised.NeilBrown
Since commit d3f761104b097738932afcc310fbbbbfb007ef92 newly allocated bvecs aren't initialised to NULL, so we have to be more careful about freeing a bio which only managed to get a few pages allocated to it. Otherwise the resync process crashes. This patch is appropriate for 2.6.29-stable.

2009-04-05ACPI: support acpi_device_ops .notify methodsBjorn Helgaas
This patch adds support for ACPI device driver .notify() methods. If such a method is present, Linux/ACPI installs a handler for device notifications (but not for system notifications such as Bus Check, Device Check, etc). When a device notification occurs, Linux/ACPI passes it on to the driver's .notify() method. In most cases, this removes the need for drivers to install their own handlers for device-specific notifications. For fixed hardware devices like some power and sleep buttons, there's no notification value because there's no control method to execute a Notify opcode. When a fixed hardware device generates an event, we handle it the same as a regular device notification, except we send a ACPI_FIXED_HARDWARE_EVENT value. This is outside the normal 0x0-0xff range used by Notify opcodes. Several drivers install their own handlers for system Bus Check and Device Check notifications so they can support hot-plug. This patch doesn't affect that usage. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Reviewed-by: Alex Chiang <achiang@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
