Changes in v2: * Now download fw during device resume * Removed runtime reference counting from driver context * Using dedicated functions instead ioctl * Addressed review comments
Subhransu S. Prusty (1): ASoC: mfld-compress: Use dedicated function instead of ioctl
Vinod Koul (4): ASoC: Intel: mrfld - add the dsp sst driver ASoC: Intel: sst: add power management handling ASoC: Intel: sst: load firmware using async callback ASoC: Intel: sst - add compressed ops handling
