From 5eaa215607c8668bfa6a7183407eba8fec63d648 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 27 Mar 2013 18:43:23 +0000 Subject: ARM: bcm2835: fix get_timer() to return ms Apparently, CONFIG_SYS_HZ must be 1000. Change this, and fix the timer driver to conform to this. Have the timer implementation export a custom API get_timer_us() for use by the BCM2835 MMC API, which needs us resolution for a HW workaround.
