Subject: [PATCH v13 03/15] mtd: spi-nor: core: add spi_nor_controller_ops_erase helper
Date: Wed, 16 Sep 2020 18:14:06 +0530 [thread overview]
Message-ID: <20200916124418.833-4-p.yadav@ti.com> (raw)
In-Reply-To: <20200916124418.833-1-p.yadav@ti.com>
It is a thin wrapper around nor->controller_ops->erase(). In a future
commit DTR support will be added. These ops can not be supported by the
erase() hook and this helper will make it easier to reject those calls.
