| | * ASoC: sh: Don't set unused struct snd_pcm_hardware fieldsLars-Peter Clausen2014-01-093-29/+0
| |/ | | | | | | | | | | | | | | | | | | | | The ASoC core assumes that the PCM component of the ASoC card transparently moves data around and does not impose any restrictions on the memory layout or the transfer speed. It ignores all fields from the snd_pcm_hardware struct for the PCM driver that are related to this. Setting these fields in the PCM driver might suggest otherwise though, so rather not set them.

| | * ASoC: rsnd: add SRC (Sampling Rate Converter) supportKuninori Morimoto2013-12-315-8/+247
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds SRC support to Renesas sound driver. SRC converts sampling rate between codec <-> cpu. It needs special codec chip, or very simple DA/AD converter to use it. This patch was tested via ak4554 codec, and supports Gen1 only at this point.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Renesas sound has SRC (= Sampling Rate Converter), but, the HW implementation depends on its generation. It was part of SRU on Gen1, and SCU on Gen2. This SCU needs DMA transfer to use it. Current rsnd driver is using it as DMA transfer buffer (= no rate convert), and Gen1 is only supported at this point. This patch cleanup it with focusing about SRC and Gen2 part. ssi clock which is calculated from rsnd_ssi_master_clk_start() should have flexibility since Renesas sound has SRC (= Sampling Rate Converter).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | R-Car sound has clock pin for each SSI, and sometimes, these pins are shared with paired SSI. It may sometimes become "SSI-A clock pin is master" and "SSI-B clock pin is slave", but "SSI-A/B clock pins are shared". SSI-B needs SSI-A clock in this case. Current R-Car sound driver is using RSND_SSI_xxx flag to control this kind of shared pin behavior. But, this information, especially clock master setting, can be got from ASoC set_fmt settings. This patch removes rsnd_ssi_mode_init() and extend rsnd_ssi_mode_set() to controlling pin settings via .set_fmt. This patch doesn't removes RSND_SSI_CLK_FROM_ADG flag at this point to avoid conflict branch merging between ASoC <-> SH-ARM.
