Subject: [PATCH] arm64: dts: ls1088a: Add QSPI support for NXP LS1088
Date: Tue, 10 Sep 2019 17:50:54 +0530	[thread overview]
Message-ID: <1568118055-9740-4-git-send-email-Ashish.Kumar@nxp.com> (raw)
In-Reply-To: <1568118055-9740-1-git-send-email-Ashish.Kumar@nxp.com>

Add QSPI node in dtsi(ls1088si), and dts(ls1088ardb, ls1088aqds) boards.

Both ls1088ardb and ls1088aqds has two 64MB flash from SPANSION(s25fs512s).
QUAD I/O is tested in case of read and single I/O is tested in case of
write.
