* ASoC: twl6040: Convert to TWL6040 MFD clientMisael Lopez Cruz2011-06-143-445/+81
| | | | | | | | | | | | | | TWL6040 CODEC driver is a client of TWL6040 MFD, following modifications are done: - skip access to shared registers (vibrator, gpo, pll) - remove shared operations (power-up/down, irq) - use new MFD APIs for register access, pll setting and irq handling - register definitions are removed from header file as already defined in MFD code Signed-off-by: Misael Lopez Cruz <misael.lopez@ti.com>
* ASoC: twl6040: Remove pll and headset mode dependencyMisael Lopez Cruz2011-06-141-9/+60
| | | | | | | | | | | | Remove dependency between pll (hppll, lppll) and headset power mode (low-power, high-performance), as headset power mode can be used with any pll. A new control is created to allow headset power mode configuration from userspace. Changing headset power mode during earpiece related usecases is not allowed as earpiece requires HS DAC in HP mode.

* mfd: twl6040: Add initial support for twl6040 mfdJorge Eduardo Candelaria2011-06-148-3/+1165
| | | | | | | | | | | | | | | | | TWL6040 IC provides analog high-end audio codec functions for handset applications. It contains several audio analog inputs and outputs as well as vibrator support. It's connected to the host processor via PDM interface for audio data communication. The audio modules are controlled by internal registers that can be accessed by I2C and PDM interface. TWL6040 MFD will be registered as a child of TWL-CORE, and will have two children of its own: twl6040-codec and twl6040-vibra This driver is based on TWL4030 and WM8350 MFD drivers.

* ALSA: pcm - reject calls to open backend PCMsLiam Girdwood2011-06-141-0/+6

* ASoC: core - add hostless DAI supportLiam Girdwood2011-06-145-0/+54
| | | | | | | | | Allow some PCM devices to be hostless, i.e. there is no PCM data transferred to or from the host CPU. This can be used to minimise power on systems since the CPU can idle/sleep during the PCM device operation (e.g. a phone call where the DAI is between a MODEM and DSP) Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
* ASoC: core - add dynamic kcontrolsLiam Girdwood2011-06-143-9/+19

* ASoC: dsp - Add ASoC DSP coreLiam Girdwood2011-06-147-55/+2061
| | | | | | | | | | | | | | This adds ASoC core support for internal and external DSPs and represents them to the audio user as a CODEC like device with mixers, muxes and runtime audio route changing. The DSP core allows DSP DAIs to be dynamically re-routed at runtime between the PCM device end (or Frontend - FE) and the physical DAI (Backend - BE) using regular kcontrols (just like a hardware CODEC). The DSP core also deal with DSP FE+BE suspend and resume PM ops. Signed-off-by: Liam Girdwood <lrg@ti.com>
* ASoC: dapm - allow custom widgets to update power events.Liam Girdwood2011-06-142-11/+32
| | | | | | | | | | | | In preparation for ASoC DSP support. Allow for the operation of custom mixer and mux DAPM widgets that can call snd_soc_dapm_mixer_update_power() and snd_soc_dapm_mux_update_power() directly after updating their status. This adds two previously static calls to the public DAPM API. Signed-off-by: Liam Girdwood <lrg@ti.com>
* ASoC: dapm - Add locking to the DAPM power_widgets()Liam Girdwood2011-06-143-4/+8
| | | | | | Add locking to the DAPM power_widgets function. Signed-off-by: Liam Girdwood <lrg@ti.com>
* ASoC: dapm - Add API call to query valid DAPM pathsLiam Girdwood2011-06-142-11/+337
| | | | | | | | | | | | | In preparation for ASoC DSP support. Add a DAPM API call to determine whether a DAPM audio path is valid between source and sink widgets. This also takes into account all kcontrol mux and mixer settings in between the source and sink widgets to validate the audio path. This will be used by the DSP core to determine the runtime DAI mappings between FE and BE DAIs in order to run PCM operations. Signed-off-by: Liam Girdwood <lrg@ti.com>
* ASoC: core - Add platform driver DAPM widgets/kcontrolsLiam Girdwood2011-06-145-14/+169
| | | | | | | | | | | In preparation for ASoC DSP support. Allow platform drivers to export widgets and kcontrols. This is required to support DSP dynamic DAI routing and power management where platform DSP drivers have kcontrols, DAPM widgets etc. Signed-off-by: Liam Girdwood <lrg@ti.com>
* ASoC: dapm - add widget IO functionsLiam Girdwood2011-06-141-6/+49
| | | | | | | | | Add widget IO in preparation to support platform driver DAPM widgets with IO. This provides a generic widget IO operation wrapper in preparation for decouplement of register IO from CODEC drivers. Signed-off-by: Liam Girdwood <lrg@ti.com>
* ASoC: core - pcm mutex per rtdLiam Girdwood2011-06-142-23/+31
| | | | | | | | | | | | | | | | | | | | | In preparation for ASoC DSP support. The new DSP core allows DSP DAIs to be dynamically re-routed at runtime between the PCM device end (or Frontend - FE) and the physical DAI (Backend - BE) using regular kcontrols (just like a hardware CODEC). The DSP core therefore must be able to call PCM operations for both the Frontend and Backend(s) DAIs at the same time. Currently we have a global pcm_mutex that is used to serialise the ASoC PCM operations. This patch removes the global mutex and adds a mutex per RTD allowing the PCM operations to be reentrant and allow control of more than one DAI at at time. e.g. a frontend DSP hw_params() could configure multiple backend hw_params() with similar or different hw parameters at the same time. Also fix the naming of soc_pcm_close. Signed-off-by: Liam Girdwood <lrg@ti.com>
* ASoC: dapm - Add DAPM stream completion eventLiam Girdwood2011-06-144-3/+18
| | | | | | | | | | | In preparation for ASoC DSP support. This adds a callback function to be called at the completion of a DAPM stream event. This can be used by DSP components to perform calculations based on DAPM graphs. Signed-off-by: Liam Girdwood <lrg@ti.com>
* ASoC: core - refactor pcm_new() to pass only rtdLiam Girdwood2011-06-1425-57/+89
| | | | | | | | | | In preparation for ASoC DSP support. Currently pcm_new() passes in card, pcm and DAI. Refactor this to only pass in rtd since rtd contains card, pcm and DAI. Struct rtd also contain other members too that are useful to DSPs. Signed-off-by: Liam Girdwood <lrg@ti.com>
* ASoC: core - Allow some components to probe/remove later or earlierLiam Girdwood2011-06-143-14/+48
| | | | | | | | | | Some ASoC components depend on other ASoC components to provide clocks and power resources in order to probe(). Provide a method to allow some components to be probed() later and be also removed() earlier. Signed-off-by: Liam Girdwood <lrg@ti.com>

* ASoC: core - Fixes for module reference countingLiam Girdwood2011-06-141-0/+5
| | | | | | | | | | | | | | | | Currently CODEC and platform drivers have their module reference count incremented soc_probe_dai_link() whilst CPU DAI drivers have their reference count incremented in soc_bind_dai_link(). CPU DAIs should have their reference count incremented in soc_probe_dai_link() just like the CODEC and platform drivers. DAI refcounting logic is simplified by by ref counting all (CODEC and platform) DAIs in each sound card, this is required in preparation for ASoC DSP as DSP components can have DAIs that can exist in either the CODEC driver or platform DAI driver.

| | | | | | | | | | | | | | | | | | | | | | Currently, when using CONFIG_DEBUG_SLAB, we put in kfree() or kmem_cache_free() as the last user of free objects, which is not very useful, so change it to the caller of those functions instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On an architecture without CMPXCHG_LOCAL but with DEBUG_VM enabled, the VM_BUG_ON() in __pcpu_double_call_return_bool() will cause an early panic during boot unless we always align cpu_slab properly. In principle we could remove the alignment-testing VM_BUG_ON() for architectures that don't have CMPXCHG_LOCAL, but leaving it in means that new code will tend not to break x86 even if it is introduced on another platform, and it's low cost to require alignment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | If we request a lock and then abort (e.g., ^C), we need to send a matching unlock request to the MDS to unwind our lock attempt to avoid indefinitely blocking other clients.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we get a short read from the OSD because the object is small, we need to zero the remainder of the buffer. For O_DIRECT reads, the attempted range is not trimmed to i_size by the VFS, so we were actually looping indefinitely. Fix by trimming by i_size, and the unconditionally zeroing the trailing range.
