Subject: [PATCH 2/2] mtd: spinand: winbond: add support for W25N01KW and W25N02LW
Date: Fri,  7 Aug 2026 12:13:39 +0530	[thread overview]
Message-ID: <20260807064339.1632249-3-md.alam@oss.qualcomm.com> (raw)
In-Reply-To: <20260807064339.1632249-1-md.alam@oss.qualcomm.com>

Add support for the Winbond W25N01KW and W25N02LW SPI-NAND
devices.

The W25N01KW shares the same geometry, OOB layout, and ECC
status handling as the existing W25N01KV, while the W25N02LW
matches the existing W25N02KV/W25N02KW devices and reuses
their OOB layout and ECC status callback.
