2013-12-11ASoC: tegra: convert to standard DMA DT bindingsStephen Warren
By passing no flags when calling snd_dmaengine_pcm_register() from tegra_pcm.c, we end up using dma_request_slave_channel() rather than dmaengine_pcm_compat_request_channel(), and hence rely on the standard DMA DT bindings and stashing the DMA slave ID away during channel allocation. This means there's no need to use a custom DT property to store the slave ID. So, remove all the code that parsed it.

2013-12-11ASoC: tegra: allocate AHUB FIFO during probe() not startup()Stephen Warren
The Tegra30 I2S driver currently allocates DMA FIFOs from the AHUB only when an audio stream starts playback. This is theoretically nice for resource sharing, but makes no practical difference for any configuration the drivers currently support. However, this deferral prevents conversion to the standard DMA DT bindings, since conversion requires knowledge of the specific DMA channel to be allocated, which in turn depends on which specific FIFO was allocated. For this reason, move the FIFO allocation into probe() to allow later conversion to the standard DMA DT bindings.

2013-12-11ASoC: tegra: call pm_runtime APIs around register accessesStephen Warren
Call pm_runtime_get_sync() before all register accesses; the HW requires clocks to be running when accessing registers. This hasn't been needed to date, since all register IO was performed while playback was active, and hence the ASoC core had already called pm_runtime_get(). However, an imminent future commit will allocate and set up the FIFOs and routing during probe(), when that "protection" won't be in place.

2013-12-11ASoC: tegra: use reset frameworkStephen Warren
Tegra's clock driver now provides an implementation of the common reset API (include/linux/reset.h). Use this instead of the old Tegra- specific API; that will soon be removed. This change also renames "clock"/"clk" to "modules"/"mod" in symbols related to entries in configlink_clocks[], since: - We don't care about clock handles any more, but rather reset handles, so the old name isn't applicable. - It really is a list of modules on the bus, about which we currently only care about reset handles. If we start caring about any other aspect of the modules in the future, we won't have to rename all these symbols again. Note: The addition of "depends COMMON_CLOCK" is something that was missing before, not a new requirement.

2013-12-11dma: tegra: register as an OF DMA controllerStephen Warren
Call of_dma_controller_register() so that DMA clients can look up the Tegra DMA controller using standard APIs. This requires the of_xlate() function to save off the DMA slave ID, and for tegra_dma_slave_config() not to over-write this information; once DMA client drivers are converted to dma_request_slave_channel() and DT-based lookups, they won't set this field of struct dma_slave_config anymore.

2013-12-10dma: add channel request API that supports deferred probeStephen Warren
dma_request_slave_channel() simply returns NULL whenever DMA channel lookup fails. Lookup could fail for two distinct reasons: a) No DMA specification exists for the channel name. This includes situations where no DMA specifications exist at all, or other general lookup problems. b) A DMA specification does exist, yet the driver for that channel is not yet registered. Case (b) should trigger deferred probe in client drivers. However, since they have no way to differentiate the two situations, it cannot. Implement new function dma_request_slave_channel_reason(), which performs identically to dma_request_slave_channel(), except that it returns an error-pointer rather than NULL, which allows callers to detect when deferred probe should occur. Eventually, all drivers should be converted to this new API, the old API removed, and the new API renamed to the more desirable name. This patch doesn't convert the existing API and all drivers in one go, since some drivers call dma_request_slave_channel() then dma_request_channel() if that fails. That would require either modifying dma_request_channel() in the same way, or adding extra error-handling code to all affected drivers, and there are close to 100 drivers using the other API, rather than just the 15-20 or so that use dma_request_slave_channel(), which might be tenable in a single patch. acpi_dma_request_slave_chan_by_name() doesn't currently implement deferred probe. It should, but this will be addressed later. Acked-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
2013-12-09ASoC: dmaengine: add custom DMA config to snd_dmaengine_pcm_configStephen Warren
Add fields to struct snd_dmaengine_pcm_config to allow custom: - DMA channel names. This is useful when the default "tx" and "rx" channel names don't apply, for example if a HW module supports multiple channels, each having different DMA channel names. This is the case with the FIFOs in Tegra's AHUB. This new facility can replace SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME. - DMA device This allows requesting DMA channels for a device other than the device which is registering the "PCM" driver. This is quite unusual, but is currently useful on Tegra. In much HW, and in Tegra20, each DAI HW module contains its own FIFOs which DMA writes to. However, in Tegra30, the DMA FIFOs were split out AHUB HW module, which then routes the data through a cross-bar, and into the DAI HW modules. However, the current ASoC driver structure does not expose this detail, and acts as if the FIFOs are still part of the DAI HW modules. Consequently, the "PCM" driver is registered with the DAI HW module, yet the DMA channels must be looked up in the AHUB HW module's device tree node. This new config field allows that to happen. Eventually, the Tegra drivers will be reworked to fully expose the AHUB, and this config field can be removed.

2013-12-05tracing: Only run synchronize_sched() at instance deletion timeSteven Rostedt
It has been reported that boot up with FTRACE_SELFTEST enabled can take a very long time. There can be stalls of over a minute. This was tracked down to the synchronize_sched() called when a system call event is disabled. As the self tests enable and disable thousands of events, this makes the synchronize_sched() get called thousands of times. The synchornize_sched() was added with d562aff93bfb53 "tracing: Add support for SOFT_DISABLE to syscall events" which caused this regression (added in 3.13-rc1). The synchronize_sched() is to protect against the events being accessed when a tracer instance is being deleted. When an instance is being deleted all the events associated to it are unregistered. The synchronize_sched() makes sure that no more users are running when it finishes. Instead of calling synchronize_sched() for all syscall events, we only need to call it once, after the events are unregistered and before the instance is deleted. The event_mutex is held during this action to prevent new users from enabling events.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound fixes from Takashi Iwai: "A usual pattern of half ASoC and half HD-audio fixes, although HD-audio fixups have more volumes, in addition to a couple of trivial fixes. Nothing to worry much is found here. For ASoC side: a few fixes for PCM rate constraints calculations, regmap byte-order fix, the rest driver specific fixes (atmel, fsl, omap, kirkwood, wm codecs). For HD-audio: Dell headset and mono out fix, ELD update in polling mode, ALC283 Chromebook fixes, a few fixes for old AD codecs and MBA2, one regression fix" * tag 'sound-3.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (30 commits) ALSA: hda - Fix silent output on MacBook Air 2,1 ALSA: hda - Fix missing ELD info when using jackpoll_ms parameter ALSA: hda/realtek - remove hp_automute_hook from alc283_fixup_chromebook ASoC: wm8731: fix dsp mode configuration ALSA: hda/realtek - Independent of model for HP ALSA: hda - Fix headset mic input after muted internal mic (Dell/Realtek) ALSA: hda - Use always amps for auto-mute on AD1986A codec ALSA: hda/analog - Handle inverted EAPD properly in vmaster hook ALSA: hda - Another fixup for ASUS laptop with ALC660 codec ALSA: atmel: Fix possible array overflow ALSA: hda - Fix complete_all() timing in deferred probes ALSA: hda - Fix bad EAPD setup for HP machines with AD1984A ASoC: core: fix devres parameter in devm_snd_soc_register_card() ASoC: omap: n810: Convert to clk_prepare_enable/clk_disable_unprepare ASoC: fsl: set correct platform drvdata in pcm030_fabric_probe() ASoC: fsl: imx-pcm-fiq: Remove unused 'runtime' variable ASoC: fsl: imx-pcm-fiq: remove bogus period delta calculation ALSA: hda - Fix silent output on ASUS W7J laptop ASoC: core: Use consistent byte ordering in snd_soc_bytes_get ALSA: dice: fix array limits in dice_proc_read() ...
