Subject: [PATCH v2] spi: efm32: Make "efm32,location" property optional
Date: Mon, 07 Apr 2014 14:42:51 +0800	[thread overview]
Message-ID: <1396852971.26619.3.camel@phoenix> (raw)

If "efm32,location" property is not provided, keeping what is already
configured in the hardware, so its either the reset default 0 or whatever
the bootloader did.
