Subject: [PATCH v3 2/2] ARM: dts: am335x-icev2: Add nodes for gpio-decoder
Date: Wed, 24 Aug 2016 13:28:59 +0530	[thread overview]
Message-ID: <20160824075859.30979-3-vigneshr@ti.com> (raw)
In-Reply-To: <20160824075859.30979-1-vigneshr@ti.com>

AM335x ICE board has a rotary-switch connected to PCA9536 I2C GPIO
expander. The position of the rotary-switch is reflected by status of
GPIO lines. Add gpio-decoder node to read these GPIO line status via
gpio-decoder driver and report it as an input event to the system.
