Subject: [PATCH v6 03/12] dt-binding: gce: add binding for gce subsys property
Date: Thu, 16 May 2019 17:02:15 +0800	[thread overview]
Message-ID: <20190516090224.59070-4-bibby.hsieh@mediatek.com> (raw)
In-Reply-To: <20190516090224.59070-1-bibby.hsieh@mediatek.com>

tcmdq driver provide a function that get the relationship
of sub system number from device node for client.
add specification for #subsys-cells, mediatek,gce-subsys.
