From 5444ea6a7f46276876e94ecf8d44615af1ef22f7 Mon Sep 17 00:00:00 2001 From: Ding Tianhong Date: Mon, 6 Feb 2017 16:47:40 +0000 Subject: [PATCH] clocksource/drivers/arm_arch_timer: Remove fsl-a008585 parameter Having a command line option to flip the errata handling for a particular erratum is a little bit unusual, and it's vastly superior to pass this in the DT. By common consensus, it's best to kill off the command line parameter.
