Subject: [PATCH 3/4] PCI: dwc: Add API to notify core initialization completion
Date: Wed, 13 Nov 2019 14:38:50 +0530	[thread overview]
Message-ID: <20191113090851.26345-4-vidyas@nvidia.com> (raw)
In-Reply-To: <20191113090851.26345-1-vidyas@nvidia.com>

Add a new API dw_pcie_ep_init_notify() to let platform drivers
call it when the core is available for initialization.
