From cfda590178a16e2b5edb09e131460b3e64819807 Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Wed, 11 Jul 2012 15:13:16 -0500 Subject: clocksource: dw_apb_timer: Add common DTS glue for dw_apb_timer Make a common device tree glue for clocksource/dw_apb_timer. Move mach-picoxcell/time.c to be a generic device tree application of the dw_apb_timer. Configure mach-picoxcell to use the dw_apb_timer_of device tree implementation in drivers/clocksource.
