Subject: [PATCH 05/11] dt-binding: Add ngpios property to GPIO controller node
Date: Mon, 19 Oct 2015 11:13:12 +0530 [thread overview]
Message-ID: <1445233398-27129-6-git-send-email-pramodku@broadcom.com> (raw)
In-Reply-To: <1445233398-27129-1-git-send-email-pramodku@broadcom.com>
Add ngpios property to the gpio controller's DT node so that controller
driver extracts total number of gpio lines present in controller
from DT and removes dependency on driver.
