2011-09-16ASoC: davinci-pcm: trivial: replace link with actual chan/linkBen Gardiner
The ambiguously named variable 'link' is used as a temporary throughout davinci-pcm -- its presence makes grepping (and groking) the code difficult. Replace link with the value of link in almost all sites. The exception is a couple places where the last-assigned link/chan needs to be returned by a function -- in these cases, rename to last_link.

Current method for machine driver to register with the ASoC core is to use snd_soc_register_card() instead of creating a "soc-audio" platform device. In addition we use platform_device_register_simple() to create a platform device for the codec. This function will handle putting and deleting the device automatically which simplifies the error handling in the machine driver.

2011-09-16ASoC: support sample sizes properly in the WM8776 codec driverTimur Tabi
Use snd_pcm_format_width() to determine the sample size, instead of checking specify sample formats and assuming that those are the only valid format. This change adds support for big-endian architectures (which use the _BE formats) and the packed 24-bit format (SNDRV_PCM_FORMAT_S24_3xE).

2011-09-15ASoC: 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.

2011-09-09ASoC: ad193x: Setup regmap read and write flag masks for SPILars-Peter Clausen
Currently register read-back for the ad193x is broken, because it expects bit 0 of the upper byte to be set to indicate a read operation, while the regmap default for SPI is to use bit 7. This patch also addresses another oddity of the device. There are SPI and I2C versions of this codec. In both cases the registers are 8-bit wide and numbered from 0x0 to 0x10, but in the SPI case there is also a so called 'global address' which is prefixed in-front of the register address. The global address mimics I2C behaviour and includes a static device address the and the read/write flag. This basically extends the register address to an 16-bit value numbered from 0x800 to 0x810. These are the register numbers which are currently used by the driver. This works, because I2C will ignore the upper 8 bits of the register, but it is still a bit confusing, as there are no such register numbers in the I2C case. The approach taken by this patch is to number the registers from 0x00 to 0x10 and encode the global address for SPI mode into the read and write flag masks.

2011-08-31ASoC: Allow source specification for CODEC level sysclkMark Brown
Similarly to PLLs/FLLs some modern CODECs provide selectable system clock sources. When the clock is the clock for a DAI we do not usually need to identify which clock is being configured so can use clk_id for the source clock but with CODEC wide system clocks we will need to specify both the clock being configured and the source. Add a source argument to the CODEC driver set_sysclk() operation to reflect this. As this operation is not as widely used as the DAI set_sysclk() operation the change is not very invasive. We probably ought to go and make the same alternation for DAIs at some point. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-08-29ASoC: davinci-mcasp: add support for unsigned PCM formatsBen Gardiner
Although the McASP supports sign-extending samples in RX or TX [1]; the davinci-mcasp driver does not touch the {R,X}PBIT or {R,X}PAD field of the {R,X}FMT registers meaning that the McASP will serialize the bytes it is given regardless of their signedness. So supporting unsigned formats is as simple as adding them to the metadata of the davinci-mcasp driver. Update the FMTBITs reported in the snd_soc_dai_driver and also update the case statements in davinci-mcasp's hw_params() function so that the McASP can be connected to CODECs that use unsigned values.
