Do not copy-and-paste wrong clock-frequency properties currently we have, but fix cpu0 along with adding cpu1..3, please. Furthermore you don't have (should not) to use clock-frequency property if you set up CNTFRQ to an appropriate value one by one in PATCH 05/05. -- Shinya Kuribayashi Renesas Electronics
