From 31ec9c2746467a372b009940ce7b722055daaf6a Mon Sep 17 00:00:00 2001 From: Ryder Lee Date: Thu, 5 Nov 2020 04:58:33 +0800 Subject: PCI: mediatek: Configure FC and FTS for functions other than 0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit "PCI_FUNC(port->slot << 3)" is always 0, so previously mtk_pcie_startup_port() only configured FC credits and FTs for function 0. Compute "func" correctly so we also configure functions other than 0. This affects MT2701 and MT7623.
