| | * | asoc/multi-component: fsl: add support for variable SSI FIFO depthTimur Tabi2010-08-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add code that programs the DMA and SSI controllers differently based on the FIFO depth of the SSI. The SSI devices on the MPC8610 and the P1022 are identical in every way except one: the transmit and receive FIFO depth. On the MPC8610, the depth is eight. On the P1022, it's fifteen. The device tree nodes for the SSI include a "fsl,fifo-depth" property that specifies the FIFO depth.

The tlv320aic3007 is similar to the aic31, but has an additional class-D speaker amp. The speaker amp control register overlaps with the mono output register of other codecs in this family, so we add logic to identify the actual codec being registered to set things up accordingly.

| | | * | ACPI / ACPICA: Fix reference counting problems with GPE handlersRafael J. Wysocki2010-08-07

Fix this issue by making acpi_install_gpe_handler() disable GPEs that were previously associated with AML methods and cannot wake up the system from sleep states. Analogously, make acpi_remove_gpe_handler() enable the GPEs that are associated with AML methods after their handlers have been removed and cannot wake up the system from sleep states. In addition to that, fix a code ordering issue in acpi_remove_gpe_handler() that renders the locking ineffective (ACPI_MTX_EVENTS is released temporarily in the middle of the routine to wait for the completion of events already in progress). For this purpose introduce acpi_raw_disable_gpe() and acpi_raw_enable_gpe() to be called with acpi_gbl_gpe_lock held and rework acpi_disable_gpe() and acpi_enable_gpe(), respectively, to use them. Also rework acpi_gpe_can_wake() to use acpi_raw_disable_gpe() instead of calling acpi_disable_gpe() after releasing the lock to avoid the possible theoretical race with acpi_install_gpe_handler().

| | | * | | ACPI: Add the check of ADR flag in course of finding ACPI handle for PCI deviceZhao Yakui2010-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The _ADR object is used to provide OSPM with the address of one device on its parent bus. In course of finding ACPI handle for the corresponding PCI device, we will firstly evaluate the _ADR object and then compare the two addresses to see whether it is the target ACPI device. But for one PCI device(0000:00:00.0) under the PCI root bridge, the corresponding address will be constructed as zero.In such case maybe the ACPI device without _ADR object will be misdetected and then be used to create the relationship between PCI device and ACPI device. https://bugzilla.kernel.org/show_bug.cgi?id=16422 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

| | | * | | | ACPI: introduce module parameter acpi.aml_debug_outputZhang Rui2010-08-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce module parameter acpi.aml_debug_output. With acpi.aml_debug_output set, we can get AML debug object output (Store (AAA, Debug)), even with CONFIG_ACPI_DEBUG cleared. Together with the runtime custom method mechanism, we can debug AML code problems without rebuilding the kernel.

Code for ACPI debugfs I/F, i.e. /sys/kernel/debug/acpi/custom_method, is moved to this file. And make ACPI debugfs always built in, even if CONFIG_ACPI_DEBUG is cleared. BTW:this adds about 400bytes code to ACPI, when CONFIG_ACPI_DEBUG is cleared.
