[PATCH net-next 2/3] ptp: clockmatrix: Remove IDT references or replace with Renesas.

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

 



From: Vincent Cheng <vincent.cheng.xh@xxxxxxxxxxx>

Renesas Electronics Corporation completed acquisition of IDT in 2019.

This patch removes IDT references or replaces IDT with Renesas.
Renamed idt8a340_reg.h to clockmatrix_reg.h.
There were no functional changes.
