Subject: [PATCH 14/14] dt-binding: mtd: physmap: Document the addr-gpios property
Date: Mon, 8 Oct 2018 22:10:27 +0200 [thread overview]
Message-ID: <20181008201027.17952-15-boris.brezillon@bootlin.com> (raw)

From: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com>
Add documentation for the addr-gpios. This extension to the physmap
binding allow creating flash devices that are paged using GPIOs.
