From 25949585ca2f31f39a5b116aee23ffa017281929 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Fri, 4 Sep 2026 20:12:48 +0200 Subject: mtd: spi-nor: winbond: Add support for W25Q64RV-Q/N There is an ID collision with the chip of same density from the JV family. Both chips are very similar in practice, it is mostly a matter of electrical differences (mostly power consumption being lower). As a significant difference, RV chips identify themselves as supporting the new SFDP (rev F) field which forces an alternate write SR2 opcode (0x31).
