Subject: [PATCH v2 2/4] gpio: aspeed: dt: Add optional clocks property
Date: Fri, 7 Apr 2017 22:29:00 +0930 [thread overview]
Message-ID: <20170407125902.15960-3-andrew@aj.id.au> (raw)
In-Reply-To: <20170407125902.15960-1-andrew@aj.id.au>
We need a reference to the HPLL to calculate debounce cycles. If the
clocks property is not supplied in the GPIO node then the consumer
should deny any debounce requests.
