Subject: [PATCH] mtd: spi-nor: Enable dual and quad read for s25fl256s0
Date: Fri, 27 Mar 2020 18:44:34 +0900
Message-ID: <20200327094434.25924-1-Takahiro.Kuwano@cypress.com> (raw)

From: Takahiro Kuwano <Takahiro.Kuwano@cypress.com>

The s25fl256s0 supports dual and quad read like s25fl256s1.
Enable it by adding SPI_NOR_DUAL_READ and SPI_NOR_QUAD_READ
flags to the flash_info entry. Tested with the device and
confirmed that is working.
