From mboxrd@z Thu Jan 1 00:00:00 1970 From: tn@semihalf.com (Tomasz Nowicki) Date: Mon, 30 May 2016 17:14:21 +0200 Subject: [PATCH V8 8/9] arm64, pci, acpi: Provide ACPI-specific prerequisites for PCI bus enumeration. In-Reply-To: <1464621262-26770-1-git-send-email-tn@semihalf.com> References: <1464621262-26770-1-git-send-email-tn@semihalf.com> Message-ID: <1464621262-26770-9-git-send-email-tn@semihalf.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org ACPI requires to run acpi_pci_{add|remove}_bus while new PCI bus is created. This allows to do some ACPI-specific additional configuration, like PCI hotplug slot enumeration. In order to fulfill these requirements, we implement arch-specific pcibios_{add|remove}_bus calls and call acpi_pci_{add|remove}_bus from there.
