* leds: remove experimental flag from leds-clevo-mailNémeth Márton2009-04-061-2/+2
| | | | | | | | The leds-clevo-mail driver is in the mainline kernel since 2.6.25 and works without severe problems. Make this driver available for a larger audience. Signed-off-by: Márton Németh <nm127@freemail.hu> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>

* leds: Add gpio-led triggerFelipe Balbi2009-04-063-0/+253
| | | | | | | | | | | | | | | | | | | | | 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.

* leds: simple driver for pwm driven LEDsLuotao Fu2009-04-064-0/+181
| | | | | | | | | | 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.

| | | | | | | | | | 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.

* leds: Add openfirmware platform device supportTrent Piepho2009-04-063-53/+219
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * audit: ignore terminating NUL in AUDIT_USER_TTY messagesMiloslav Trmac2009-04-051-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AUDIT_USER_TTY, like all other messages sent from user-space, is sent NUL-terminated. Unlike other user-space audit messages, which come only from trusted sources, AUDIT_USER_TTY messages are processed using audit_log_n_untrustedstring(). This patch modifies AUDIT_USER_TTY handling to ignore the trailing NUL and use the "quoted_string" representation of the message if possible.

| * Audit: fix handling of 'strings' with NULL charactersMiloslav Trmac2009-04-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | currently audit_log_n_untrustedstring() uses audit_string_contains_control() to check if the 'string' has any control characters. If the 'string' has an embedded NULL audit_string_contains_control() will return that the data has no control characters and will then pass the string to audit_log_n_string with the total length, not the length up to the first NULL. audit_log_n_string() does a memcpy of the entire length and so the actual audit record emitted may then contain a NULL and then whatever random memory is after the NULL. Since we want to log the entire octet stream (if we can't trust the data to be a string we can't trust that a NULL isn't actually a part of it) we should just consider NULL as a control character. If the caller is certain they want to stop at the first NULL they should be using audit_log_untrustedstring.

EXECVE records contain a newline after every argument. auditd converts "\n" to " " so you cannot see newlines even in raw logs, but they're there nevertheless. If you're not using auditd, you need to work round them. These '\n' chars are can be easily replaced by spaces when creating record in kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver requests a clock that usually is supplied by the MFD in which the DS1WM is contained. Currently, it is impossible for a MFD to register their clocks with the generic clock API due to different implementations across architectures. For now, this patch removes the clock handling from DS1WM altogether, trusting that the MFD enable/disable functions will switch the clock if needed. The clock rate is obtained from a new parameter in driver_data. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>

| * | | | ACPI: button: use .notify method instead of installing handler directlyBjorn Helgaas2009-04-051-69/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a .notify() method. The presence of .notify() causes Linux/ACPI to manage event handlers and notify handlers on our behalf, so we don't have to install and remove them ourselves. Note that events from fixed hardware buttons now show up as a special notify event, so to preserve user-space backward compatibility, we convert that back to ACPI_BUTTON_NOTIFY_STATUS.

| * | | | ACPI: support acpi_device_ops .notify methodsBjorn Helgaas2009-04-053-0/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
