Subject: [PATCH 06/15] mtd: st_spi_fsm: Add support for Macronix MX25L3255E
Date: Wed, 26 Mar 2014 16:39:20 +0000 [thread overview]
Message-ID: <1395851969-13520-7-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1395851969-13520-1-git-send-email-lee.jones@linaro.org>
From: Angus Clark <angus.clark@st.com>
This patch adds support for the Macronix MX25L3255E device. Unlike the other
Macronix devices we have seen, this device supports WRITE_1_4_4 at reasonable
frequencies. Rather than masking out WRITE_1_4_4 support altogether, we now
rely on the table parameters to indicate whether or not WRITE_1_4_4 should be
used.
