[PATCH v7 0/5] clk: add driver for the SiFive FU740
From: Zong Li
Date: Wed Dec 09 2020 - 04:50:10 EST
Add a driver for the SiFive FU740 PRCI IP block, which handles more
clocks than FU540. These patches also refactor the original
implementation by spliting the dependent-code of fu540 and fu740
respectively.
We also add a separate patch for DT binding documentation of FU740 PRCI:
