From a47ef6e93ab2ca1db8d5ecb61fda3c41f926a26b Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Tue, 1 Sep 2020 09:39:10 +0800 Subject: hw/riscv: clint: Avoid using hard-coded timebase frequency At present the CLINT timestamp is using a hard-coded timebase frequency value SIFIVE_CLINT_TIMEBASE_FREQ. This might not be true for all boards. Add a new 'timebase-freq' property to the CLINT device, and update various functions to accept this as a parameter.
