[PATCH] riscv: dts: microchip: Define hart clocks

From: Bin Meng
Date: Wed Jun 16 2021 - 02:27:24 EST


From: Bin Meng <bin.meng@xxxxxxxxxxxxx>

Declare that each hart in the DT is clocked by <&clkcfg 0>.

Similar to https://patchwork.kernel.org/project/linux-riscv/patch/1592308864-30205-3-git-send-email-yash.shah@xxxxxxxxxx/,
this adds the same <clock> property to PolarFire SoC CPU nodes so that we can
calculate the running frequency of the hart.
