In certain situations, such as when returning from low power modes, the
EMIF must re-run hardware leveling to properly restore DDR3 access.

This is accomplished by introducing a new ti-emif-sram-pm call,
ti_emif_run_hw_leveling, to check if DDR3 is in use and if so, trigger
the full write and read leveling processes.

OK nice that you also consider devices with LPDDR2 then in case we
start seeing those.

Yes, LPDDR2 will work fine with these. Any thoughts on if this series should
come through you or Santosh?

Probably best that I queue these since there's also
arch/arm/mach-omap2 code related changes.

Santosh, is this OK with you? Care to ack the patch?

Sure Tony !!
