Subject: [RFC] ARM: DTS: da850-evm: Refactor device tree layout
Date: Thu, 26 Apr 2018 21:35:49 -0500 [thread overview]
Message-ID: <20180427023549.13678-1-aford173@gmail.com> (raw)
Many of the items in the device tree are already defined or partially
defined, so let's remove the redundancies and reduce the whitespace.
