Subject: [PATCH v9 09/10] PCI: qcom-ep: Use the generic dw_pcie_ep_linkdown() API to handle LINK_DOWN event
Date: Mon, 04 Mar 2024 14:52:21 +0530	[thread overview]
Message-ID: <20240304-pci-dbi-rework-v9-9-29d433d99cda@linaro.org> (raw)
In-Reply-To: <20240304-pci-dbi-rework-v9-0-29d433d99cda@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.
