From 911612989d8224e1e37e47438dac29330f0798ff Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 28 Jan 2021 11:41:43 +0000 Subject: [PATCH] arm: Don't set freq properties on CMSDK timer, dualtimer, watchdog, ARMSSE MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
