The default clock (48 MHz) is too fast for the system timer. Signed-off-by: Paul Cercueil <paul@crapouillou.net> --- Notes: v5: New patch v6: Set also the rate for the clocksource channel's clock v7: No change v8: No change v9: Don't configure clock timer1, as the OS Timer is used as clocksource on this SoC v10: Revert back to v8 bahaviour. Let the user choose what clocksource should be used. v11-v12: No change arch/mips/boot/dts/ingenic/ci20.dts | 7 +++++++ 1 file changed, 7 insertions(+)
