Subject: [PATCH 6/6] arm64: dts: k3-j721e: Add gpio-keys on common processor board
Date: Fri, 9 Aug 2019 13:59:47 +0530 [thread overview]
Message-ID: <20190809082947.30590-7-lokeshvutla@ti.com> (raw)
In-Reply-To: <20190809082947.30590-1-lokeshvutla@ti.com>
From: Nikhil Devshatwar <nikhil.nd@ti.com>
Common processor board for K3 J721E platform has two push buttons
namely SW10 and SW11.
Add a gpio-keys device node to model them as input keys in Linux.
Add required pinmux nodes to set GPIO pins as input.
