2013-08-26ASoC: fsi: reserve prefetch period on DMA transferringKuninori Morimoto
Current FSI is supporting DMAEngine transfer, but, it needs to use work queue. Therefore, DMA transfer settings might be late if there is heavy task. This patch reserves next period beforehand on DMA transfer function. Android sound will be breaking up without this patch.

2012-11-06ASoC: fsi: add master clock control functionsKuninori Morimoto
Current FSI driver required set_rate() platform callback function to set audio clock if it was master mode, because it seemed that CPG/FSI-DIV clocks calculation depend on platform/board/cpu. But it was calculable regardless of platform. This patch supports audio clock calculation method, but the sampling rate under 32kHz is not supported at this point.

Current FSI driver is using fsi_set_master_clk() if it needs system clock. But this function was called from fsi_hw_shutdown()/fsi_dai_trigger()/fsi_resume() without a sense of unity. Because of this, sound playback after suspend failed sometimes. To keep consistency, fsi_master_clk() was called from fsi_hw_start/stop() only now.

SupherH FSI2 can use special data transfer, but it depends on CPU-FSI2 connection style.
