Subject: [PATCH V3 06/14] ARM: dts: stm32: Add QSPI NOR on AV96
In-Reply-To: <20200331175136.205020-1-marex@denx.de>
References: <20200331175136.205020-1-marex@denx.de>
Message-ID: <20200331175136.205020-7-marex@denx.de>

The DH Electronics DHCOR SOM has QSPI NOR on the SoM itself, add it
into the DT.
