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>
