ASoC: add Renesas R-Car core feature Renesas R-Car series sound circuit consists of SSI and its peripheral. But this peripheral circuits are different between R-Car Generation1 (E1/M1/H1) and Generation2 (E2/M2/H2). (Actually, there are many difference in Generation1 chips) Basically, for the future, Renesas R-Car series will use Gen2 style sound circuit, but driver should care Gen1 also. The main differences between Gen1 and Gen2 peripheral are 1) register offset, 2) data path. This patch adds basic (core) feature for R-Car series sound driver as prototype Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>

ASoC: rsnd: route setting is needed only Gen1 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. rsnd_scu_set_route() is needed only Gen1. This patch renames it to rsnd_scu_set_route_if_gen1() and it adds comment to rsnd_reg member in order to clarify it is used for Gen1.

ASoC: add Renesas R-Car core feature Renesas R-Car series sound circuit consists of SSI and its peripheral. But this peripheral circuits are different between R-Car Generation1 (E1/M1/H1) and Generation2 (E2/M2/H2). (Actually, there are many difference in Generation1 chips) Basically, for the future, Renesas R-Car series will use Gen2 style sound circuit, but driver should care Gen1 also. The main differences between Gen1 and Gen2 peripheral are 1) register offset, 2) data path. This patch adds basic (core) feature for R-Car series sound driver as prototype Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>

ASoC: rsnd: add SRC (Sampling Rate Converter) support 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.

ASoC: rsnd: remove platform dai and add dai_id on platform setting Current rsnd driver is using struct rsnd_dai_platform_info so that indicate sound DAI information (playback/capture SSI ID). But, SSI settings were also required separately. Thus, platform settings was very un-understandable. This patch adds dai_id to SSI settings, and removed rsnd_dai_platform_info.

ASoC: rsnd: SSI_MODE0/1 settings goes to scu.c SRU (Gen1) / SCU (Gen2) / SSIU (Gen2) are controlled under scu.c. (SCU + SSIU (Gen2) was SRU (Gen1)) And register of SSI_MODE0/1 are mapped on these IP. But these have been implemented under ssi.c on this driver.
