[PATCH v2 00/10] ARM: DTS/clk: DRA7 family: enable eDMA and audio updates

[Peter Ujfalusi]

Tony,

according to Nishanth, linux-next is broken for dra7 family:
http://pastebin.ubuntu.com/15758542/ on x15 next-20160411
because of the missing DT patches.
Do you want me to resend this series w/o the hwmod patch?
