Merge series "ASoC: SOF: multi core support for 5.10" from Kai Vehmanen <kai.vehmanen@linux.intel.com>:
This series extends the multi-core support in SOF. Capability
to specify which core to use, on a per component basis, is added
to topology. The topology load functionality in SOF is modified to
power up/down host controlled cores based on the topology
description.
Guennadi Liakhovetski (2):
ASoC: SOF: add a "core" parameter to widget loading functions
ASoC: SOF: support topology components on secondary cores
Ranjani Sridharan (1):
ASoC: SOF: topology: fix core enable sequence
