Subject: [PATCH v2 1/2] riscv: hw: Drop "clock-frequency" property of cpu nodes
Date: Fri, 20 Sep 2019 22:41:30 -0700 [thread overview]
Message-ID: <1569044491-7875-1-git-send-email-bmeng.cn@gmail.com> (raw)
The "clock-frequency" property of cpu nodes isn't required. Drop it.
This is to keep in sync with Linux kernel commit below:

Changes in v2:
- drop the one in spike and virt machines too
