git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "This is the first big chunk for 3.5 merges of sound stuff. There are a few big changes in different areas. First off, the streaming logic of USB-audio endpoints has been largely rewritten for the better support of "implicit feedback". If anything about USB got broken, this change has to be checked. For HD-audio, the resume procedure was changed; instead of delaying the resume of the hardware until the first use, now waking up immediately at resume. This is for buggy BIOS. For ASoC, dynamic PCM support and the improved support for digital links between off-SoC devices are major framework changes. Some highlights are below: * HD-audio - Avoid accesses of invalid pin-control bits that may stall the codec - V-ref setup cleanups - Fix the races in power-saving code - Fix the races in codec cache hashes and connection lists - Split some common codes for BIOS auto-parser to hda_auto_parser.c - Changed the PM resume code to wake up immediately for buggy BIOS - Creative SoundCore3D support - Add Conexant CX20751/2/3/4 codec support * ASoC - Dynamic PCM support, allowing support for SoCs with internal routing through components with tight sequencing and formatting constraints within their internal paths or where there are multiple components connected with CPU managed DMA controllers inside the SoC. - Greatly improved support for direct digital links between off-SoC devices, providing a much simpler way of connecting things like digital basebands to CODECs. - Much more fine grained and robust locking, cleaning up some of the confusion that crept in with multi-component. - CPU support for nVidia Tegra 30 I2S and audio hub controllers and ST-Ericsson MSP I2S controolers - New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124, Texas Instruments LM49453. - Some regmap changes needed by the Tegra I2S driver. - mc13783 audio support. * Misc - Rewrite with module_pci_driver() - Xonar DGX support for snd-oxygen - Improvement of packet handling in snd-firewire driver - New USB-endpoint streaming logic - Enhanced M-audio FTU quirks and relevant cleanups - Increment the support of OSS devices to 256 - snd-aloop accuracy improvement There are a few more pending changes for 3.5, but they will be sent slightly later as partly depending on the changes of DRM." Fix up conflicts in regmap (due to duplicate patches, with some further updates then having already come in from the regmap tree).

The check was originally intended to allow the same header file to be used on 85xx and 86xx systems, even though the Global Utilities register could be different. It turns out that they're not actually different, and so the check is not necessary. In addition, neither macro is defined for 64-bit e5500 kernels, so that causes a build break.

2012-03-17ASoC: fsl: p1022ds: tell the WM8776 codec driver that it's the masterTimur Tabi
The WM8776 codec driver requires the machine driver to set one of the SND_SOC_DAIFMT_CBx_xxx values. The P1022DS machine driver should be setting SND_SOC_DAIFMT_CBM_CFM, but since that value was zero, no one noticed. Commit 75d9ac46 ("ASoC: Allow DAI formats to be specified in the dai_link"), however, changed the value of SND_SOC_DAIFMT_CBM_CFM from zero to a non-zero value, which means that it now needs to be specifically set by the machine driver.

Instead of using the 'cell-index' property in the I2C adapter node to determine the adapter number, just query the i2c_adapter object directly. Previously, the I2C nodes always appeared in cell-index order, so the dynamic numbering coincided with the cell-index property. With commit ab827d97 ("powerpc/85xx: Rework P1022DS device tree"), the I2C nodes are unintentionally reversed in the device tree, and so the machine driver guesses the wrong I2C adapter number.

The later is not surprising since existing drivers are often used as templates for new drivers. So this patch just constifies all existing snd_soc_dai_ops structs to eliminate the issue altogether.

2011-09-16ASoC: improve asynchronous mode support in the fsl_ssi driverTimur Tabi
The Freescale SSI audio controller supports "synchronous" and "asynchronous" modes. In synchronous mode, playback and capture use the same input clock, so sample rates must be the same during simultaneous playback and capture. Unfortunately, the code which supports asynchronous mode is just broken in various ways. In particular, it was constraining sample sizes as well as the sample rate. The fix also allows us to simplify the code by eliminating the 'asynchronous', 'playback', and 'capture' variables that were used to keep track of playback and capture streams. Unfortunately, it turns out that simulataneous playback and record does not actually work on the only platform that supports asynchronous mode: the Freescale P1022DS reference board. If a second stream is started, the SSI grinds to halt for both streams. This is true even if the P1022 is configured for synchronous mode, so it's likely a hardware problem that needs to be worked around.

2011-08-24ASoC: MPC5200: replace of_device with platform_deviceTimur Tabi
'struct of_device' no longer exists, and its functionality has been merged into platform_device. Update the MPC5200 audio DMA driver (mpc5200_dma) accordingly. This fixes a build break.

2011-08-22sound/soc/fsl/mpc8610_hpcd.c: add missing of_node_putJulia Lawall
The first change is to add an of_node_put, since codec_np has previously been allocated. The rest of the patch reorganizes the error handling code so the only code executed is that which is needed. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier x; expression E1!=0,E2,E3,E4; statement S; iterator I; @@ ( if (...) { ... when != of_node_put(x) when != x = E3 when != E3 = x * return ...; } ... when != x = E2 when != I(...,x,...) S if (...) { ... when != x = E4 of_node_put(x); ... return ...; } ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Timur Tabi <timur@freescale.com> Acked-by: Liam Girdwood <lrg@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-08-22sound/soc/fsl/p1022_ds.c: add missing of_node_putJulia Lawall
dma_channel_np has been accessed at this point, so decrease its reference count before leaving the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier x; expression E1!=0,E2,E3,E4; statement S; iterator I; @@ ( if (...) { ... when != of_node_put(x) when != x = E3 when != E3 = x * return ...; } ... when != x = E2 when != I(...,x,...)

2011-08-22sound/soc/fsl/fsl_dma.c: add missing of_node_putTimur Tabi
of_parse_phandle increments the reference count of np, so this should be decremented before trying the next possibility. Since we don't actually use np, we can decrement the reference count immediately.

2011-08-17ASoC: claim the IRQ when the fsl_ssi device is probed, not openedTimur Tabi
The PowerPC Freescale SSI driver is claiming the IRQ when the IRQ when the device is opened, which means that the /proc/interrupts entry for the SSI exists only during playback or capture. This also meant that the user won't know that the IRQ number is wrong until he tries to use the device. Instead, we should claim the IRQ when the device is probed.
