2012-01-09ENGR00161014 ASoC: don't clobber platform DMA driver opsAlan Tull
Previously, only one static struct for ops existed for all platform DMA drivers to share. Half of the ops are shared functions which don't have stubs in the ALSA core. The other half are initialized to point directly to ops in the platform driver. This creates problems where each time soc_new_pcm is called, the new platform driver's ops would overwrite a subset of the ops. Signed-off-by: Alan Tull <alan.tull@freescale.com>
2011-06-30ALSA: sb16 - Fix build errors on MIPS and others with 13bit ioctl sizeTakashi Iwai
One of ioctl definition in sound/sb16_csp.h contains the data size over 8kB, and this causes build errors on architectures like MIPS, which define _IOC_SIZEBITS=13. For avoiding this build errors but keeping the compatibility, manually expand with _IOC() instead of using _IOW() for the problematic ioctl. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-05-03ASoC: Store a list of widgets in a DAPM mux/mixer kcontrolStephen Warren
A future change will allow multiple widgets to be affected by the same control. For example, a single register bit that controls separate muxes in both the L and R audio paths. This change updates the code that handles relevant controls to be able to iterate over a list of affected widgets. Note that only the put functions need significant modification to implement the iteration; the get functions do not need to iterate, nor unify the results, since all affected widgets reference the same kcontrol. When creating the list of widgets, always create a 1-sized list, since the control sharing is not implemented in this change.

2011-03-25ALSA: vmalloc buffers should use normal mmapBenjamin Herrenschmidt
It's a big no-no to use pgprot_noncached() when mmap'ing such buffers into userspace since they are mapped cachable in kernel space. This can cause all sort of interesting things ranging from to garbled sound to lockups on various architectures. I've observed that usb-audio is broken on powerpc 4xx for example because of that. Also remove the now unused snd_pcm_lib_mmap_noncached(). It's an arch business to know when to use uncached mappings, there's already hacks for MIPS inside snd_pcm_default_mmap() and other archs are supposed to use dma_mmap_coherent(). (See my separate patch that adds dma_mmap_coherent() to powerpc) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-03-22ALSA: Add snd_ctl_replace() to dynamically replace a controlDimitris Papastamos
Add a function to dynamically replace a given control. If the control does not already exist, a third parameter is used to determine whether to actually add that control. This is useful in cases where downloadable firmware at runtime can add or replace existing controls. A separate patch needs to be made to allow ALSA Mixer to render the replaced controls on the fly.

2011-03-08ASoC: Provide CODEC clocking operations and API callsMark Brown
When multi component systems use DAIless amplifiers which require clocking configuration it is at best hard to use the current clocking API as this requires a DAI even though the device may not even have one. Address this by adding set_sysclk() and set_pll() operations and APIs for CODECs. In order to avoid issues with devices which could be used either with or without DAIs make the DAI variants call through to their CODEC counterparts if there is no DAI specific operation. Converting over entirely would create problems for multi-DAI devices which offer per-DAI clocking setup.
