# Topology for generic Apollolake board with no codec and digital mic array.
#
# APL Host GW DMAC support max 6 playback and max 6 capture channels so some
# pipelines/PCMs/DAIs are commented out to keep within HW bounds. If these
# are needed then they can be used provided other PCMs/pipelines/SSPs are
# commented out in their place.

# Include topology builder
include(`utils.m4')
include(`dai.m4')
include(`ssp.m4')
include(`pipeline.m4')

# Include TLV library
include(`common/tlv.m4')

# Include Token library
include(`sof/tokens.m4')

# Include Apollolake DSP configuration
