[net-next PATCH v6 12/16] net: dsa: qca8k: add support for QCA8328

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
