Linux-3.10 LTSI: Missing R-Car Sound Support on Marzen (R8A7779)

[srikanth krishnakar]

I am trying to boot the Renesas R-Car H1 (Marzen) board with 3.10 LTSi
kernel which is present at :

https://git.kernel.org/cgit/linux/kernel/git/horms/renesas-backport.git/

Branch: backport/v3.10.28-ltsi-rc1/snapshot

There are no sound cards detected on booting this kernel, although
graphics is found to be working. Are there any updates which adds the
RCAR_SOUND support to Marzen on v3.10 LTSi kernel ?

When will be the Audio support available for R-Car Marzen (R8A7779) on
v3.10 LTSi kernel ?
