Renesas R-Car series sound circuit consists of SSI and its peripheral. But this peripheral circuit is different between R-Car Generation1 (E1/M1/H1) and Generation2 (E2/M2/H2) (Actually, there are many difference in Generation1 chips) This patch adds SCU feature on this driver. But, it defines SCU style only, does nothing at this point. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
