From ba9f316986502471b160470e5e27a5e5a2ccadaf Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Wed, 20 May 2020 01:24:52 +0200 Subject: [PATCH] dt-bindings: mtd: nand: Document the generic rb-gpios property 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.
