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