Subject: [v3, 1/4] dt-binding: reset-controller: ti: add reset-duration-us property
Date: Mon, 17 Aug 2020 10:48:39 +0800 [thread overview]
Message-ID: <20200817024842.5289-2-crystal.guo@mediatek.com> (raw)
In-Reply-To: <20200817024842.5289-1-crystal.guo@mediatek.com>
introduce 'reset' method to allow device do serialized assert and
deassert operations in a single step, which needs a minimum delay
to be waited between assert and deassert.
