Subject: [PATCH 1/2] mtd: m25p80: Revive dual read support
Date: Tue, 22 Apr 2014 14:45:31 +0200 [thread overview]
Message-ID: <1398170732-19773-1-git-send-email-geert+renesas@glider.be> (raw)
Commit 03e296f613affcc2671c1e86d8c25ecad867204e ("mtd: m25p80: use the SPI
nor framework") accidentally removed support for Dual SPI read transfers.
Add it back.
