Subject: Changing SiFive Unleashed core clock rate on 5.x kernel
Date: Mon, 12 Aug 2019 17:32:30 -0300 [thread overview]
Message-ID: <CADnnUqcp_7yN4WK2uXberCV_uwjPSj0PxpiXg6kp71--QGPJaA@mail.gmail.com> (raw)
Back in 4.x kernel, we could set the board clock rate by echoing like:
echo 1450000000 > /sys/devices/platform/soc/10000000.prci/rate
Now with Kernel 5.x and with the board DTB, what's the correct way to
set this clock rate? I tried changing RTCCLK_FREQ from 1000000 to
1450000 but I got some clock skew during use.
Is there anywhere else this need to be set?
Thanks
