Subject: [PATCH v2 3/9] mtd: spi-nor: fsl-quadspi: add fast-read mode support
Date: Fri, 22 Apr 2016 14:39:46 +0800	[thread overview]
Message-ID: <1461307192-866-3-git-send-email-B56489@freescale.com> (raw)
In-Reply-To: <1461307192-866-1-git-send-email-B56489@freescale.com>

From: Yunhui Cui <yunhui.cui@nxp.com>

The qspi driver add generic fast-read mode for different
flash venders. There are some different board flash work on
different mode, such fast-read, quad-mode.
