Subject: [PATCH v4] mtd: spinand: dosilicon: Add support for additional models
Date: Wed, 27 May 2026 09:07:54 -0400	[thread overview]
Message-ID: <20260527130754.10867-1-ses1er@gmail.com> (raw)

Add support for additional Dosilicon SPI NAND chips.

Datasheets for chips included in this patch: https://www.dosilicon.com/SPI%20NAND%20Flash.html

Tested on a TP-Link TL-7DR7250 with a Dosilicon DS35Q1GB (0xE5 0xF1)
