Subject: [PATCH] clocksource: time-efm32: Select CLKSRC_MMIO
Date: Wed, 20 Nov 2013 10:15:11 +0800	[thread overview]
Message-ID: <1384913711.13115.2.camel@phoenix> (raw)

The time-efm32 driver uses the clocksource MMIO functions.
Thus it needs to select CLKSRC_MMIO in Kconfig.

Signed-off-by: Axel Lin <axel.lin@ingics.com>

This fixes build error when COMPILE_TEST=y.
