Subject: [PATCH 1/2] dt-bindings: PCI: mediatek-gen3: Add property to disable dvfsrc voltage request
Date: Fri, 14 May 2021 14:59:26 +0800	[thread overview]
Message-ID: <20210514065927.20774-2-jianjun.wang@mediatek.com> (raw)
In-Reply-To: <20210514065927.20774-1-jianjun.wang@mediatek.com>

Add property to disable dvfsrc voltage request, if this property
is presented, we assume that the requested voltage is always
higher enough to keep the PCIe controller active.
