From ea2c6df478550fd5e4a412412cea30c986883808 Mon Sep 17 00:00:00 2001 From: Vaishnav Achath Date: Mon, 25 Nov 2024 16:19:47 +0530 Subject: [PATCH] mtd: spi-nor-core: Fixup SNOR_F_IO_MODE_EN_VOLATILE for MT35X MT35XU512ABA has only BFPT and 4-Byte Address Instruction Table in SFDP. commit bebdc237507c ("mtd: spi-nor: Parse SFDP SCCR Map") added checks in spi_nor_octal_dtr_enable() to bail out if the 22nd DWORD in SCCR does not indicate DTR Octal Mode Enable, since MT35XU512ABA device supports octal DTR mode, add this property in SFDP fixup.
