Subject: [PATCH v2 2/4] dt-bindings: mtd: nand: Document the generic rb-gpios property
Date: Wed, 20 May 2020 01:24:52 +0200	[thread overview]
Message-ID: <20200519232454.374081-2-boris.brezillon@collabora.com> (raw)
In-Reply-To: <20200519232454.374081-1-boris.brezillon@collabora.com>

A few drivers use this property to describe GPIO pins used to sample
the NAND Ready/Busy state. Let's make it part of the generic binding
doc.
