Subject: [PATCH AUTOSEL 4.14 030/127] mtd: rawnand: sunxi: Write pageprog related opcodes to WCMD_SET
Date: Fri, 22 Nov 2019 00:54:08 -0500 [thread overview]
Message-ID: <20191122055544.3299-29-sashal@kernel.org> (raw)
In-Reply-To: <20191122055544.3299-1-sashal@kernel.org>
From: Boris Brezillon <boris.brezillon@bootlin•com>
[ Upstream commit 732774437ae01d9882e60314e303898e63c7f038 ]
The opcodes used by the controller when doing batched page prog should
be written in NFC_REG_WCMD_SET not FC_REG_RCMD_SET. Luckily, the
default NFC_REG_WCMD_SET value matches the one we set in the driver
which explains why we didn't notice the problem.
