Subject: [PATCH 1/2] mtd: nand: spi: Only one dummy byte in QUADIO
Date: Wed, 10 Feb 2021 19:36:19 +0100 [thread overview]
Message-ID: <20210210183620.20952-1-code@reto-schneider.ch> (raw)
From: Reto Schneider <reto.schneider@husqvarnagroup.com>
The datasheet only lists one dummy byte in the 0xEH operation for the
following chips:
* GD5F1GQ4xBxxG
* GD5F1GQ4xExxG
* GD5F1GQ4xFxxG
* GD5F1GQ4UAYIG
* GD5F4GQ4UAYIG
This patch and its commit message reflects what has been done in Linux
and has not been tested by me.
