ARM: dts: r8a7794: add sound support
Define the generic R8A7794 part of the sound device node. This sound device is a complex one and comprises the Audio Clock Generator (ADG), Sampling Rate Converter Unit (SCU), Serial Sound Interface [Unit] (SSI[U]), and Audio DMAC-Peripheral-Peripheral. It is up to the board file to enable the device. This patch is based on the R8A7791 sound work by Kuninori Morimoto. Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Acked-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
