Subject: [PATCH v2 2/2] mfd: stmpe: Document DT binding for irq_over_gpio
Date: Fri, 12 Sep 2014 11:18:34 +0800 [thread overview]
Message-ID: <1410491914-23378-3-git-send-email-xobs@kosagi.com> (raw)
In-Reply-To: <1410491914-23378-1-git-send-email-xobs@kosagi.com>
STMPE now supports using a GPIO as an IRQ source. Document the device
tree binding for this option.
