Hi Sebastian,

Could you pick up the following patch for mach-bcm/ into this series?

Thanks,
Matt

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.
