The wm8782 supports higher audio rates than just 48kHz. This is configured by setting the FSAMPEN pin on the codec chip.
This patch series introduces the 'wlf,fsampen' device tree property to indicate the pin status and control the maximum rate available when using the codec.
v2 -> v3: - Rate is now properly constrained using ALSA constraints
v1 -> v2: - Switched from max-rate property to wlf,fsampen property - Clarified property is optional, not required
John Watts (3): ASoC: wm8782: Constrain maximum audio rate at runtime ASoC: wm8782: Use wlf,fsampen device tree property ASoC: dt-bindings: wlf,wm8782: Add wlf,fsampen property
