Subject: [PATCH v2 5/7] ARM: dts: imx6ul: add ARM architected timer
Date: Wed, 10 Jan 2018 22:04:51 +0100 [thread overview]
Message-ID: <20180110210453.19264-5-stefan@agner.ch> (raw)
In-Reply-To: <20180110210453.19264-1-stefan@agner.ch>
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.
