Subject: [RFC/RFT PATCH v1 7/9] mtd: spi: Add SPI_NOR_DUAL_READ property for the 'n25q128a13' Micron memory
Date: Thu, 27 Sep 2018 00:07:37 +0200	[thread overview]
Message-ID: <20180926220739.620-8-lukma@denx.de> (raw)
In-Reply-To: <20180926220739.620-1-lukma@denx.de>

This memory supports not only QUAD reads, but DUAL as well.

Those are needed when two identical memories are used, but one is not
using four lines for read I/O.
