   4 Subject: [PATCH] overlays: audremap: Fix setting of the pin function
   5
   6 The brcm,function property must be set in the overlay fragment too -
   7 otherwise the parametrization won't work. At least that's the case for
   8 bcm2711-rpi-cm4.dts which starts with empty properties:
   9
  10 &gpio {
  11         audio_pins: audio_pins {
  12                 brcm,pins = <>;
  13                 brcm,function = <>;
  14         };
  15 };
  16
  17 This was broken since a56df85d2f42fd461fdc05f33617141aca5ba465.
