Unfortunately this patch does not seem to result in a working sound device on the Ebisu board. I have tried adding backports of the following patches: * 42b35c5991cc ("pinctrl: sh-pfc: r8a77990: Add Audio SSI pins, groups and functions") * 42b35c5991cc ("pinctrl: sh-pfc: r8a77990: Add Audio SSI pins, groups and functions") * 42b35c5991cc ("pinctrl: sh-pfc: r8a77990: Add Audio SSI pins, groups and functions") However, although the rcar-snd driver appears to be probed successfully it does not result in an alsa sound device being registered. This also appears to be the case with BSP v3.7.2.rc2. Probably I am missing something obvious here...
