[PATCH 1/1] net: wireless: ath: wcn36xx: add support for pronto-v3

From: Sireesh Kodali
Date: Sat Mar 11 2023 - 10:07:37 EST


From: Vladimir Lypak <vladimir.lypak@xxxxxxxxx>

Pronto v3 has a different DXE address than prior Pronto versions. This
patch changes the macro to return the correct register address based on
the pronto version.
