Subject: [PATCH v6 3/5] mtd: nand: mtk-ecc: also parse nand-ecc-engine if available
Date: Sun, 24 Apr 2022 11:25:25 +0800 [thread overview]
Message-ID: <20220424032527.673605-4-gch981213@gmail.com> (raw)
In-Reply-To: <20220424032527.673605-1-gch981213@gmail.com>
The recently added ECC engine support introduced a generic property
named nand-ecc-engine for ecc engine phandle. This patch adds support
for this new property.
Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
