Thanks for this. Yes rebase seems to have caused many issues so I am redoing it
right now. Will let you know once the tree is updated

There were multiple issues with the latest rebase done on 3.8-rc2.
Over that there is an issue in
this patch, due to which merge with ARM-SoC tree was broken... I have
fixed rebase
and merge issues in below patch. Please pick it up:
(ARM mail servers are facing some issues now a days and so patch would
be broken,
hence attaching it too)

Subject: [PATCH] ARM: SPEAr13xx: Pass DW DMAC platform data from DT
This patch adds dw_dmac's platform data to DT node. It also creates slave info
node for SPEAr13xx, for the devices which were using dw_dmac.
