Subject: [PATCH v1 3/5] mtd: nand: raw: rockchip-nand-controller: fix nand timing default
Date: Thu, 8 Jun 2023 18:30:40 +0200 [thread overview]
Message-ID: <f8a10a00-c3e4-9749-789d-39fba7944646@gmail.com> (raw)
In-Reply-To: <19bf714a-43f9-c30a-8197-91aaaf4a6e5d@gmail.com>
Somehow not all NAND chips give a valid timing setting with the
nand_get_sdr_timings() function. Don't consider it as an error,
but fall back to the default value in order to continue to use
the driver.
