Subject: [PATCH 01/14] mtd: nand: nand-mxs: Move register definitions to separate file
Date: Tue, 1 Nov 2022 16:30:35 +0100 [thread overview]
Message-ID: <20221101153048.772146-2-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20221101153048.772146-1-s.hauer@pengutronix.de>
The GPMI registers are needed in the MTD GPMI driver and also in the
xload-gpmi driver. So far both use their own set of register defines.
Move the MTD GPMI register defines to include/ so that we can use them
in the xload driver as well.
