From mboxrd@z Thu Jan 1 00:00:00 1970 From: tn@semihalf.com (Tomasz Nowicki) Date: Mon, 8 Aug 2016 14:56:41 +0200 Subject: [RFC PATCH V5 4/5] ARM64/PCI: Start using quirks handling for ACPI based PCI host controller In-Reply-To: <1470661002-26213-1-git-send-email-tn@semihalf.com> References: <1470661002-26213-1-git-send-email-tn@semihalf.com> Message-ID: <1470661002-26213-5-git-send-email-tn@semihalf.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Since there are platforms which have non-compliant ECAM space we need to override these accessors prior to PCI buses enumeration. In order to do that we call pci_mcfg_match_quirks() to retrieve custom pci_config_window structure. If no correlated quirk on list, use fully ECAM compliant generic PCI config accessors.
