Subject: [PATCH 1/2] rnndb: Separate MDP5 domain from MDSS domain
Date: Mon,  9 Mar 2015 09:12:29 -0400

MDP block is actually contained inside the MDSS block. For some
chipsets, the base address of the MDP registers is different from the
current (assumed) 0x100 offset.

Like CTL and  LM blocks, this changes introduce a dynamic offset
for the MDP instance, which can be found out at runtime, once the
MDSS HW version is read.
