This patch set is aimed at the i.MX6 MMDC driver:
Patch 1 is a bug fix for the "write-accesses" event definition.
Patch 2 adds AXI address filter support for MMDC profiling.
v2: added prefix for patch subjects.

Add support for an extra config parameter for perf commands:
axi_id, which will be written in the MMDC's MADPCR1 register,
to filter memory usage profiling (see i.MX6 reference manual,
chapter 44.7 MMDC Profiling for AXI id usage).
