Subject: [PATCH] clocksource: ftm: select CLKSRC_MMIO
Date: Thu, 14 Jan 2016 00:02:13 +0100 [thread overview]
Message-ID: <11970328.RVc8t0Mk1C@wuerfel> (raw)
The ftm clocksource driver does not build if CLKSRC_MMIO is disabled:
drivers/built-in.o: In function `ftm_timer_init':
(init.text+0xd324): undefined reference to `clocksource_mmio_init'
(init.text+0xd484): undefined reference to `clocksource_mmio_readl_up'
This adds the same 'select' statement that the other similar drivers
use. Prior to allowing this driver to be enabled with COMPILE_TEST,
it was apparently unused. I'm not entirely sure who is using this
hardware, but it certainly can't hurt to ensure it builds cleanly.
