Subject: [PATCH v4 2/3] mtd: spinand: add spinand_read_cfg() helper
Date: Fri, 28 May 2021 16:16:38 +0200	[thread overview]
Message-ID: <20210528141639.3194-3-patrice.chotard@foss.st.com> (raw)
In-Reply-To: <20210528141639.3194-1-patrice.chotard@foss.st.com>

From: Patrice Chotard <patrice.chotard@foss.st.com>

Put REG_CFG reading code in spinand_read_cfg().
This function will be needed by the future SPI-NAND resume ops.
