Subject: [PATCH 0/7] soundwire: add support for link clock source selection

Since CannonLake, we've been using the XTAL oscillator as the link clock
source, but since MeteorLake the hardware offers two additional sources:
the audio cardinal clock and the internal audio PLL.

This series adds support for link clock source selection.

Pierre-Louis Bossart (7):
  soundwire: cadence: show the bus frequency and frame shape
  soundwire: bus: extend base clock checks to 96 MHz
  soundwire: intel: add more values for SYNCPRD
  soundwire: intel: add support for MeteorLake additional clocks
  soundwire: intel_ace2x: move and extend clock selection
  soundwire: intel_ace2.x: power-up first before setting SYNCPRD
  soundwire: intel_ace2x: set the clock source
