[0/6] Add support of two Audio PLL source

Message

Shengjiu Wang June 30, 2022, 5:39 a.m. UTC

i.MX8MQ/MN/MM/MP platforms typically have 2 AUDIO PLLs being
configured to handle 8kHz and 11kHz series audio rates.

The patches implement the functionality to select at runtime
the appropriate AUDIO PLL for root clock, if there is no
two PLL registered, then no action taken.

Shengjiu Wang (6):
  ASoC: fsl_utils: Add function to handle PLL clock source
  ASoC: fsl_spdif: Add support for PLL switch at runtime.
  ASoC: fsl_micfil: Add support for PLL switch at runtime
  ASoC: fsl_sai: Add support for PLL switch at runtime
  ASoC: dt-bindings: fsl_spdif: Add two PLL clock source
  ASoC: dt-bindings: fsl-sai: Add two PLL clock source
