Subject: [PATCH] ARM: dts: imx6sx-sdb: Add QSPI support
Date: Fri, 17 Oct 2014 15:39:32 -0300 [thread overview]
Message-ID: <1413571172-30940-1-git-send-email-festevam@gmail.com> (raw)
From: Fabio Estevam <fabio.estevam@freescale.com>
imx6sx-sdb has two s25fl128s quad spi flash. Add support for them.
Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

There are still some extra patches needed to get s25fl128s supported.
They were already sent into mtd-list, but have not been applied yet.
However, the dts part could go independently.
