Subject: [PATCH 3/3] ARM: dts: keystone-k2g-evm: add bindings for SPI NOR flash
Date: Fri, 8 Sep 2017 15:46:38 -0500	[thread overview]
Message-ID: <20170908204638.13149-4-fcooper@ti.com> (raw)
In-Reply-To: <20170908204638.13149-1-fcooper@ti.com>

From: Murali Karicheri <m-karicheri2@ti.com>

K2G EVM has n25q128a13 SPI NOR flash on SPI1. Enable SPI1 in the DT
node as well as add a subnode for the SPI NOR.
