Merge series "ASoC: SOF: Intel and IMX updates for 5.8" from Kai Vehmanen <kai.vehmanen@linux.intel.com>:

Hi,

here's a series of minor fixes and improvements to SOF. Add support
for smart amplifier component type. Cover more systems by relaxing
match rules for the generic Soundwire machine driver. Fix issues with
driver unload and address a few compiler warnings.

Daniel Baluta (2):
  ASoC: SOF: Do nothing when DSP PM callbacks are not set
  ASoC: SOF: define INFO_ flags in dsp_ops

Keyon Jie (1):
  ASoC: SOF: topology: add support to smart amplifier

Marcin Rajwa (2):
  ASoC: SOF: add a power_down_notify method
  ASoC: SOF: inform DSP that driver is going to be removed

Pierre-Louis Bossart (2):
  ASoC: SOF: imx: make dsp_ops static
  ASoC: SOF: imx: make imx8m_dsp_ops static

randerwang (1):
  ASoC: SOF: Intel: sdw: relax sdw machine select constraints
