From ebe35aff883496c07248df82c8576c3b6e84bbbe Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Fri, 29 Aug 2008 05:55:51 +0200 Subject: [ARM] Orion: prepare for runtime-determined timer tick rate Currently, orion5x uses a hardcoded timer tick rate of 166 MHz, but the actual timer tick rate varies between different members of the SoC family (and can vary based on strap pin settings). This patch prepares for runtime determination of the timer tick rate.
