* [PATCH v3] mtd: spi-nor: Add support for N25Q256A13 @ 2017-03-02 2:42 Nobuhiro Iwamatsu 2017-03-07 22:11 ` Cyrille Pitchen 0 siblings, 1 reply; 4+ messages in thread From: Nobuhiro Iwamatsu @ 2017-03-02 2:42 UTC (permalink / raw) To: linux-mtd; +Cc: Nobuhiro Iwamatsu, Jagan Teki, Marek Vasut, Cyrille Pitchen Add new Micron N25Q256A (N25Q256A13) 256Mbit NOR Flash in the list of supported devices. This chip has the same structure as the N25Q256A but ID and voltage (1V8) to use is different. Therefore, this adds N25Q256A13 as n25q256ax1. In the future, for new Micron memories we could use the patterns "n25q*ax1" for 1V8 and "n25q*ax3" for 3V3 memories.
