2014-01-13ALSA: hda - Don't set indep_hp flag for old AD codecsTakashi Iwai1-8/+8
Some old AD codecs don't like the independent HP handling, either it contains a single DAC (AD1981) or it mandates the mixer routing (AD1986A). This patch removes the indep_hp flag for such codecs.

2014-01-11ALSA: Enable CONFIG_ZONE_DMA for smaller PCI DMA masksTakashi Iwai1-0/+12
The PCI devices with DMA masks smaller than 32bit should enable CONFIG_ZONE_DMA. Since the recent change of page allocator, page allocations via dma_alloc_coherent() with the limited DMA mask bits may fail more frequently, ended up with no available buffers, when CONFIG_ZONE_DMA isn't enabled. With CONFIG_ZONE_DMA, the system has much more chance to obtain such pages.

2014-01-11ALSA: PCM: Warn when buffer preallocation failsTakashi Iwai1-0/+5
The failures of buffer preallocations at driver initializations aren't critical but it's still helpful to inform, so that user can know that something doesn't work as expected. For example, the recent page allocator change triggered regressions, but developers didn't notice until recently because the driver didn't complain. Signed-off-by: Takashi Iwai <[email protected]>
2014-01-10ALSA: ctxfi - Work around emu20k1 glitch to prevent buffered sound data lossSarah Bessmer1-0/+5
Occasionally, on playback stream ringbuffer wraparound, the EMU20K1 hardware will momentarily return 0 instead of the proper current(loop) address. This patch handles that case, fixing the problem of playback position corruption and subsequent loss of buffered sound data, that occurs with some common buffering layout patterns(e.g. multiple simultaneous output streams with differently-sized or non-power-of-2-sized buffers). An alternate means of fixing the problem would be to read the ca register continuously, until two sequential reads return the same value; however, that would be a more invasive change, has performance implications, and isn't necessary unless there are also issues with the value not being updated atomically in regards to individual bits or something similar(which I have not encountered through light testing). I have no EMU20K2 hardware to confirm if the issue is present there, but even if it's not, this change shouldn't break anything that's not already broken.

2014-01-09ALSA: Merge memalloc code into snd-pcm moduleTakashi Iwai2-16/+4
Instead of keeping a separate snd-page-alloc module, merge into the core snd-pcm module, as we don't need to keep it as an individual module due to the drop of page reservation. Signed-off-by: Takashi Iwai <[email protected]>

2014-01-09ALSA: Remove memory reservation code from memalloc helperTakashi Iwai7-321/+18
Nowadays we have CMA for obtaining the contiguous memory pages efficiently. Let's kill the old kludge for reserving the memory pages for large buffers. It was rarely useful (only for preserving pages among module reloading or a little help by an early boot scripting), used only by a couple of drivers, and yet it gives too much ugliness than its benefit.

2014-01-08ALSA: hda - Split Thinkpad ACPI-related codeTakashi Iwai3-187/+105
Both patch_realtek.c and patch_conexant.c contain the fairy same code snippet for supporting Thinkpad ACPI LED controls. Split them into thinkpad_helper.c and include it from both places. Although this isn't the best approach from the code size POV, the probability for coexistence of both Realtek and Conexant codecs on a single machine is pretty low, thus it'll end up with less memory footprint than splitting to yet another module.

2014-01-08ALSA: hda - Don't create duplicated ctls for loopback pathsTakashi Iwai1-2/+4
AD1986A mic pins (0x1d and 0x1f) share the same widget for controlling the loopback volume/mute, but the generic parser didn't check it. This ended up with the duplicated controls for the same effect. This patch adds the check of the duplication for avoiding it. After this fix, there will be only one control although it affects both paths; this remaining issue should be fixed later in a different patch.

Some tags used in the firmware patch file are inconsistent with hwdep sysfs file names, such as, the firmware patch takes [hint] tag while sysfs file is */hints.

2014-01-08ALSA: hda - Increment default stream numbers for AMD HDMI controllersTakashi Iwai1-2/+2
It turned out that some AMD HDMI controllers still don't provide proper values in GCAP register (all zero), and the driver assigns only one stream in that case, although the connected codec chip supports more than one stream. In this patch, the default max number of streams for AMD HDMI controllers is increased to 8, which should suffice for most use cases. The overhead by this increase is more azx_dev struct and BDL allocations, so it's negligible. Of course, if the controller provides a proper GCAP register, the register value would be used.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v3.14 Not a lot going on framework wise, partly due to Christmas at least in the case of the work I've been doing, but there's been quite a lot of cleanup activity going on and the usual trickle of new drivers: - Update to the generic DMA code to support deferred probe and managed resources. - New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090 and Analog Devices AXI I2S and S/PDIF controller IPs. - Device tree support for the simple card, max98090 and cs42l52. - Conversion of the Samsung drivers to native dmaengine, making them multiplatform compatible and hopefully helping keep them more modern and up to date. - More regmap conversions, including a very welcome one for twl6040 from Peter Ujfalusi. - A big overhaul of the DaVinci drivers also from Peter Ujfalusi.

2013-12-31ASoC: imx-spdif: Use snd-soc-dummy CODEC driver to link cardNicolin Chen2-64/+21
This is a quick fix for the below two issues when building spdif as modules. 1) If modprobing modules in order: (Step 1) snd-soc-fsl-spdif -> (Step 2) snd-soc-imx-spdif -> (Step 3) snd-soc-spdif-tx/rx, we will fail to create imx-spdif card and dai link unless we rmmod snd-soc-imx-spdif and modprobe it again due to the execution platform_driver_unregister() in probe() when meeting -EPROBE_DEFER at Step 2. 2) After "imx-spdif sound-spdif.17: dit-hifi <-> 2004000.spdif mapping ok", 'rmmod snd-soc-imx-spdif' would cause kernel dump with warning: WARNING: CPU: 0 PID: 1301 at /home/rmk/git/linux-rmk/fs/sysfs/dir.c:915 sysfs_hash_and_remove+0x84/0x90() sysfs: can not remove 'dapm_widget', no directory This should be caused by disordered resourse releasing of the whole link. And trying to unregister the card and then CODEC dev can't fix this issue. Thus this patch just provides a simple fix to these two bugs by using the snd-soc-dummy in the core instead of seperate snd-soc-spdif-tx/rx so that there's no need to handle the registering and unregistering of CODEC or CODEC dai any more.
