Subject: [PATCH 23/25] arm: Don't set freq properties on CMSDK timer, dualtimer, watchdog, ARMSSE
Date: Thu, 21 Jan 2021 19:06:20 +0000	[thread overview]
Message-ID: <20210121190622.22000-24-peter.maydell@linaro.org> (raw)
In-Reply-To: <20210121190622.22000-1-peter.maydell@linaro.org>

Remove all the code that sets frequency properties on the CMSDK
timer, dualtimer and watchdog devices and on the ARMSSE SoC device:
these properties are unused now that the devices rely on their Clock
inputs instead.
