Subject: [PATCH] arm64: dts: fsl: ls1046: Modify the qspi flash frequency
Date: Tue, 21 May 2019 09:40:09 +0000 [thread overview]
Message-ID: <20190521150336.8409-1-pankaj.bansal@nxp.com> (raw)
The qspi flash in ls1046a based QDS and RDB boards can operate
at 50MHz frequency.
Therefore, update the maximum supported freq in their respective
dts files.
