Morimoto-san: Are the base addresses configured in DT? I did a quick search for 0xec300000, 0xec320000, 0xec40000, 0xec420000, and 0xec000000, and couldn't find them in DT, only in source code (comments). They must come from somewhere? Note that I didn't follow the sound binding discussions that closely.
This base addresses are specified from sound driver.
- sound driver specifies src/dst address by DMAEngine API
From the rcar_sound node? That one has 0xec500000 as the base address.
- audmapp find necessary ID from src/dst address
