Hi Sebastian, Could you pick up the following patch for mach-bcm/ into this series? Thanks, Matt From f65d048b3453447bb3e693cb21701c4d0c6375ed Mon Sep 17 00:00:00 2001 From: Matt Porter Date: Fri, 20 Sep 2013 13:41:06 -0400 Subject: [PATCH] ARM: bcm: Remove custom .time_init hook With arch/arm calling of_clk_init(NULL) and clocksource_of_init() this is no longer needed. The former is useful because we can make use of dummy fixed clocks for drivers until the bcm281xx common clock driver is ready.
