* ASoC: dmaengine-pcm: Rename and deprecate snd_dmaengine_pcm_pointerLars-Peter Clausen2012-06-201-1/+1
| | | | | | | | | | | | | | | | | | | Currently the sound dmaengine pcm helper functions implement the pcm_pointer callback by trying to count the number of elapsed periods. This is done by advancing the stream position in the dmaengine callback by one period. Unfortunately there is no guarantee that the callback will be called for each elapsed period. It may be possible that under high system load it is only called once for multiple elapsed periods. This patch renames the current implementation and documents its shortcomings and that it should not be used anymore in new drivers. The next patch will introduce a new snd_dmaengine_pcm_pointer which will be implemented based on querying the current stream position from the dma device.

* ASoC: ux500: Don't make the CPU I2S driver user selectableMark Brown2012-05-101-3/+1
| | | | | | | It can only be used with a machine driver so the idiomatic thing for ASoC is to select this driver from the machine driver. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
