Subject: [PATCH v2 0/3] mtd: spinand: add support for detection with param page
Date: Fri, 15 Apr 2022 11:48:41 +0800 [thread overview]
Message-ID: <20220415034844.1024538-1-gch981213@gmail.com> (raw)
This patchset adds support for spi-nand detection using parameter page.
This helps dealing with future JEDEC ID conflicts introduced by crazy
vendors. Also, the added ability to auto-detect chip capacity can help
reducing number of entries in our spi-nand id table.
Change since v1: extract common functions from raw nand
Chuanhong Guo (3):
mtd: nand: extract some onfi functions to nandcore
mtd: spinand: add support for detection with param page
mtd: spinand: probe Winbond W25N01GV/W using param page
