From f477d1c8bdbef4f400718238e350f16f521d2a3e Mon Sep 17 00:00:00 2001 From: Ansuel Smith Date: Thu, 14 Oct 2021 00:39:17 +0200 Subject: [PATCH] net: dsa: qca8k: add support for QCA8328 QCA8328 switch is the bigger brother of the qca8327. Same regs different chip. Change the function to set the correct pin layout and introduce a new match_data to differentiate the 2 switch as they have the same ID and their internal PHY have the same ID.
