[PATCH 2/3] riscv: dts: fu540-c000: define hart clocks

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

 



Declare that each hart defined in the FU540 DT data is clocked by the
COREPLL. This is in preparation for enabling CPUFreq for the
FU540-C000 SoC on the HiFive Unleashed board.
