Subject: [PATCH v2 2/2] ARM: dts: vf610-zii-dev: Add QSPI node
Date: Wed, 22 May 2019 00:20:52 -0700	[thread overview]
Message-ID: <20190522072052.2829-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190522072052.2829-1-andrew.smirnov@gmail.com>

Both rev C and rev B of the board come with two QSPI-NOR chips
attached to the SoC. Add DT code describing all of this.
