Subject: [PATCH 3/4] mtd: spinand: Add M70A series Micron SPI NAND devices
Date: Sun, 19 Jan 2020 15:54:31 +0100 [thread overview]
Message-ID: <20200119145432.10405-4-sshivamurthy@micron.com> (raw)
In-Reply-To: <20200119145432.10405-1-sshivamurthy@micron.com>
From: Shivamurthy Shastri <sshivamurthy@micron.com>
Add device table for M70A series Micron SPI NAND devices.
While at it, disable the Continuous Read feature which is enabled by
default.
