Acked-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> This patch doesn't use SRC, and it is no problem.

Define the SILK board dependent part of the R8A7794 sound device node. Add device node for Asahi Kasei AK4643 stereo codec to the I2C1 bus. Add the "simple-audio-card" device node to interconnect the SoC sound device and the codec. This patch is based on the commit 493b4da7c10c ("ARM: dts: porter: add sound support"). Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> --- This patch is against the 'renesas-devel-20160209-v4.5-rc3' tag of Simon Horman's 'renesas.git' repo. It depends on the 5 R8A7794 sound support patches in posted earlier this week in order to build and the R8A7794 PFC driver patches posted yesterday in order for the pins to be properly configured (but works without the pins configured too)... arch/arm/boot/dts/r8a7794-silk.dts | 71 +++++++++++++++++++++++++++++++++++++ 1 file changed, 71 insertions(+)
