[PATCH 08/12] MIPS: ath79: add support for the PCI host controller of the AR71XX SoCs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


The Atheros AR71XX SoCs have a built-in PCI Host Controller.
This patch adds a driver for that, and modifies the relevant
files in order to allow to register the PCI controller from
board specific setup.
