git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM DT updates from Olof Johansson: "As usual, this is the massive branch we have for each release. Lots of various updates and additions of hardware descriptions on existing hardware, as well as the usual additions of new boards and SoCs. This is also the first release where we've started mixing 64- and 32-bit DT updates in one branch.

If the link has already been brought up by firmware, we need not call dw_pcie_setup_rc(), and "num-lanes" is unnecessary.

2015-10-16Docs: dt: Add PCI MSI map bindingsMark Rutland
Currently msi-parent is used by a few bindings to describe the relationship between a PCI root complex and a single MSI controller, but this property does not have a generic binding document. Additionally, msi-parent is insufficient to describe more complex relationships between MSI controllers and devices under a root complex, where devices may be able to target multiple MSI controllers, or where MSI controllers use (non-probeable) sideband information to distinguish devices. This patch adds a generic binding for mapping PCI devices to MSI controllers. This document covers msi-parent, and a new msi-map property (specific to PCI*) which may be used to map devices (identified by their Requester ID) to sideband data for each MSI controller that they may target.

2015-06-05PCI: xgene: Add APM X-Gene v1 PCIe MSI/MSIX termination driverDuc Dang
APM X-Gene v1 SoC supports its own implementation of MSI, which is not compliant to GIC V2M specification for MSI Termination. There is a single MSI block in X-Gene v1 SOC which serves all 5 PCIe ports. This MSI block supports 2048 MSI termination ports coalesced into 16 physical HW IRQ lines and shared across all 5 PCIe ports. As there are only 16 HW IRQs to serve 2048 MSI vectors, to support set_affinity correctly for each MSI vectors, the 16 HW IRQs are statically allocated to 8 X-Gene v1 cores (2 HW IRQs for each cores). To steer MSI interrupt to target CPU, MSI vector is moved around these HW IRQs lines. With this approach, the total MSI vectors this driver supports is reduced to 256.

2015-02-04Documentation: DT bindings: add more Tegra chip compatible stringsPaul Walmsley
Align compatible strings for several IP blocks present on Tegra chips with the latest doctrine from the DT maintainers: http://marc.info/?l=devicetree&m=142255654213019&w=2 The primary objective here is to avoid checkpatch warnings, per: http://marc.info/?l=linux-tegra&m=142201349727836&w=2 DT binding text files have been updated for the following IP blocks: - PCIe - SOR - SoC timers - AHB "gizmo" - APB_MISC - pinmux control - UART - PWM - I2C - SPI - RTC - PMC - eFuse - AHCI - HDA - XUSB_PADCTRL - SDHCI - SOC_THERM - AHUB - I2S - EHCI - USB PHY N.B. The nvidia,tegra20-timer compatible string is removed from the nvidia,tegra30-timer.txt documentation file because it's already mentioned in the nvidia,tegra20-timer.txt documentation file. This second version takes into account the following requests from Rob Herring <robherring2@gmail.com>: - Per-IP block patches have been combined into a single patch - Explicit documentation about which compatible strings are actually matched by the driver has been removed. In its place is implicit documentation that loosely follows Rob's prescribed format: "Must contain '"nvidia,<chip>-pcie", "nvidia,tegra20-pcie"' where <chip> is tegra30, tegra132, ..."

2014-09-16PCI: keystone: Assume controller is already in RC modeMurali Karicheri
Keystone PCI hardware supports both RC and EP modes and devcfg register has bits to boot strap the device to either of these modes. It seems proper to add this functionality to the boot loader rather than in the driver as device will be operating in either mode, not both any time. Currently the driver supports only RC mode and hence register configuration in the driver is not needed and the driver can assume the hardware is in RC mode. Also update the DT documentation accordingly. Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Arnd Bergmann <arnd@arndb.de>

2014-09-04PCI: designware: Parse bus-range property from devicetreeLucas Stach
This allows to explicitly specify the covered bus numbers in the devicetree, which will come in handy once we see a SoC with more than one PCIe host controller instance. Previously the driver relied on the behavior of pci_scan_root_bus() to fill in a range of 0x00-0xff if no valid range was found. We fall back to the same range if no valid DT entry was found to keep backwards compatibility, but now do it explicitly.

2014-09-04PCI: keystone: Add TI Keystone PCIe driverMurali Karicheri
The Keystone PCIe controller is based on v3.65 version of the Designware h/w. Main differences are: 1. No ATU support 2. Legacy and MSI IRQ functions are implemented in application register space 3. MSI interrupts are multiplexed over 8 IRQ lines to the Host side. All of the application register space handing code is organized into pci-keystone-dw.c and the functions are called from pci-keystone.c to implement PCI controller driver. Also add necessary DT documentation and update the MAINTAINERS file for the driver.

2014-09-03powerpc: fsl_pci: Add forced PCI Agent enumerationAaron Sierra
The following commit prevents the MPC8548E on the XPedite5200 PrPMC module from enumerating its PCI/PCI-X bus: powerpc/fsl-pci: use 'Header Type' to identify PCIE mode The previous patch prevents any Freescale PCI-X bridge from enumerating the bus, if it is hardware strapped into Agent mode. In PCI-X, the Host is responsible for driving the PCI-X initialization pattern to devices on the bus, so that they know whether to operate in conventional PCI or PCI-X mode as well as what the bus timing will be. For a PCI-X PrPMC, the pattern is driven by the mezzanine carrier it is installed onto. Therefore, PrPMCs are PCI-X Agents, but one per system may still enumerate the bus. This patch causes the device node of any PCI/PCI-X bridge strapped into Agent mode to be checked for the fsl,pci-agent-force-enum property. If the property is present in the node, the bridge will be allowed to enumerate the bus.

2014-07-22PCI: designware: Look for configuration space in 'reg', not 'ranges'Kishon Vijay Abraham I
The configuration address space has so far been specified in *ranges*, however it should be specified in *reg* making it a platform MEM resource. Hence used 'platform_get_resource_*' API to get configuration address space in the designware driver.
