Subject: [RFC PATCH V2 0/4] APM X-Gene PCIe controller
Date: Tue, 14 Jan 2014 15:34:14 -0800 [thread overview]
Message-ID: <1389742458-7693-1-git-send-email-tinamdar@apm.com> (raw)
This patch adds support for AppliedMicro X-Gene PCIe host controller. The
driver is tested on X-Gene platform with different gen1/2/3 PCIe endpoint
cards.
X-Gene PCIe controller driver has depedency on the pcie arch support for
arm64. The arm64 pcie arch support is not yet part of mainline Linux kernel
and approach for arch support is under discussion with arm64 maintainers.
The reference patch can be found here --> https://lkml.org/lkml/2013/10/23/244
If someone wishes to test PCIe on X-Gene, arch support patch must be applied
before the patches in this patch set.
changes since V1:
1. added PCI domain support
2. reading cpu and pci addresses from device tree to configure regions.
3. got rid of unnecessary wrappers for readl and writel.
4. got rid of endpoint configuration code.
5. added 'dma-ranges' property support to read inbound region configuration.
6. renamed host driver file to 'pci-xgene.c' from 'pcie-xgene.c'
7. dropped 'clock-names' property from bindings
8. added comments whereever requested.
