| * ASoC: TWL4030: Add actual support for 96KHz playback supportPeter Ujfalusi2009-04-03
| | | | | | | | | | | | | | Adds the needed code to be able to use 96KHz playback. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@nokia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

| * ASoC: Set parent for AC97 devices we registerMark Brown2009-04-02
| | | | | | | | | | | | | | | | | | Ensure that any AC97 devices that bind to the CODEC are below the ASoC device in the device tree so the suspend and resume code can figure out what order to handle them in.

| * ASoC: Don't defer resume work for AC97 codecsMark Brown2009-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AC97 devices may have other drivers hanging off them directly so need to have resumed when the resume function returns meaning that we can't defer the resume - complete it immediately for them. Non-AC97 devices should not have other drivers hanging directly off the ASoC devices. We only really need the deferral for non-AC97 devices - it's there since some I2C buses are very slow and non-AC97 codecs often have large numbers of registers to restore and require delays to bring the codec up cleanly leading to a substantial impact on overall resume time.

| * ASoC: OMAP: Set minimum buffer size constraint for McBSP2 in OMAP3Jarkko Nikula2009-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | McBSP2 in OMAP3 has 1 ksample (1k x 32 bit) internal FIFO. During initial playback startup, this FIFO is keeping the DMA request active until the FIFO is full. So now if ALSA buffer size is smaller, DMA is looping around it while filling up the HW FIFO, generating burst of interrupts as well and SW doesn't have any change to fill enough data.

| | | | | | | | | | | | | | | | | | | | Optimize the display of SSI statistics in the Freescale MPC8610 sound driver to display the status count only of the interrupts that were actually enabled.

| | | | | | | | | | | | | | | | | | the variable gsr_bit is set in isr. It is however set to 0 and interrupts are disabled prior to reset. Hence it doesn't make a lot of sense to show the content of gsr_bit in case of a reset timeout.

| * ASoC: remove trigger delay in Freescale MPC8610 sound driverTimur Tabi2009-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the delay from the trigger function in the Freescale MPC8610 sound driver when capture is started. This delay was used to ensure that the DMA controller was active when ALSA call the .pointer function to request a DMA transfer status. A better approach is for the .pointer function to detect that DMA has not started, and return zero instead. This change eliminates the need for the delay. Also add some related code to check for a DMA programming error, and report XRUN if it occurs.

| * ASoC: Add Magician machine supportPhilipp Zabel2009-04-02
| | | | | | | | | | | | | | | | | | | | | | | | HTC Magician has a Philips UDA1380 codec connected via SSP1 (playback) and I2S (capture). There is a flip-flop between the SSP frame clock output and the codec's word select input pin. To make the codec see proper I2S input, the SSP has to send two frames per sample.

| * | audit: ignore terminating NUL in AUDIT_USER_TTY messagesMiloslav Trmac2009-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Trmac2009-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: processor: use .notify method instead of installing handler directlyBjorn Helgaas2009-04-05

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.

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 Helgaas2009-04-05

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>
