Subject: [PATCH v2 08/10] PCI: qcom-ep: Use the generic dw_pcie_ep_linkdown() API to handle Link Down event
Date: Mon, 01 Apr 2024 21:20:34 +0530	[thread overview]
Message-ID: <20240401-pci-epf-rework-v2-8-970dbe90b99d@linaro.org> (raw)
In-Reply-To: <20240401-pci-epf-rework-v2-0-970dbe90b99d@linaro.org>

Now that the API is available, let's make use of it. It also handles the
reinitialization of DWC non-sticky registers in addition to sending the
notification to EPF drivers.
