Subject: [PATCH RFC] spi: efm32: Make "efm32,location" property optional
Date: Mon, 07 Apr 2014 11:18:52 +0800 [thread overview]
Message-ID: <1396840732.7635.2.camel@phoenix> (raw)
The spi driver still works even if "efm32,location" property is not provided.
Thus make "efm32,location" property optional.
