2011-03-26ASoC: soc-cache: Introduce raw bulk write supportDimitris Papastamos
As it has become more common to have to write firmware or similar large chunks of data to the hardware, add a function to perform raw bulk writes that bypass the cache. This only handles volatile registers as we should avoid getting out of sync with the actual cache.

2011-03-18ASoC: Remove bogus check for register validity in debugfs writeMark Brown
Since not all registers need to be cached and the cache is entirely optional anyway we shouldn't be checking that a register is in the cached range. If the register is invalid then the actual I/O code can determine that and report an error. Similarly, the step size can and should be enforced by the lower level code if it's important.

2011-03-11ASoC: mini2440: Fix uda134x codec problem.Marek Belisko
ASoC audio for mini2440 platform in current kenrel doesn't work. First problem is samsung_asoc_dma device is missing in initialization. Next problem is with codec. Codec is initialized but never probed because no platform_device exist for codec driver. It leads to errors during codec binding to asoc dai. Next problem was platform data which was passed from board to asoc main driver but not passed to codec when called codec_soc_probe(). Following patch should fix issues. But not sure if in correct way. Please review.

2011-03-09ASoC: Fix double addition of prefixes due to widget prefixingMark Brown
We're not only prefixing all controls, we're also prefixing the widget names in the runtime data. This causes us to add the prefix twice - once when using the widget name to generate the control name and once when adding the control. Really we shouldn't be prefixing the widget names at all, the matching code should be handing this as we always know which DAPM context a widget came from and always display the widget name in terms of a DAPM context. However, we're quite close to the merge window and that's relatively invasive.

2011-03-08ASoC: Warn rather than set a silly constraint when we can't do symmetryMark Brown
Symmetric rate configuration can fail if the second stream starting tries to apply the symmetric constraint before the first stream has got far enough to pick a rate.

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.
