# Initial SOF module will contain

# 1. Application logic - pipeline, audio components, IPC processing, topology
# 2. IP drivers - SSP, DMIC, PM, IPC will transition to Zephyr directly over
#                 time and be removed from the SOF repo.
# 3. Platform IP - PM, init, clocks, IRQs will transition directly to Zephyr
#                  over time and be removed from SOF repo.
# 4. RTOS logic - scheduler, allocator, notifier - as with 2 & 3.
