[PATCH 5/7] ARM: dts: imx6ul: add ARM architected timer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Add per-core ARM architected timer. Unfortunately bootloaders (U-Boot)
currently do not make the necessary initialization. Also specifing the
clock manually using the clock-frequency property seems not to help.
Therefor leave the timer disabled by default for now.
