Docs: dt: add PCI IOMMU map bindings
The existing IOMMU bindings are able to specify the relationship between masters and IOMMUs, but they are insufficient for describing the general case of hotpluggable busses such as PCI where the set of masters is not known until runtime, and the relationship between masters and IOMMUs is a property of the integration of the system. This patch adds a generic binding for mapping PCI devices to IOMMUs, using a new iommu-map property (specific to PCI*) which may be used to map devices (identified by their Requester ID) to sideband data for the IOMMU which they master through.

bindings: PCI: artpec: correct pci binding example
- Increase config size. When using a PCIe switch, the previous config size only had room for one device. - Add bus range. Inherited optional property. - Map downstream I/O to PCI address 0. We can map it to any address, but let's be consistent with other drivers. Signed-off-by: Niklas Cassel <niklas.cassel@axis.com> Signed-off-by: Rob Herring <robh@kernel.org> |

Devicetree for 4.7:
- Rewrite of the unflattening code to avoid recursion and lessen the stack usage. - Rewrite of the phandle args parsing code to get rid of the fixed args size. This is needed for IOMMU code. - Sync to latest dtc which adds more dts style checking. These warnings are enabled with "W=1" compiles. - Tegra documentation updates related to the above warnings. - A bunch of spelling and other doc fixes. - Various vendor prefix additions. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJXP3OZAAoJEPr7XbWNvGHDEUAQAJLbR9Js7RENPGX/u0NSJNaJ yQhyNVsz/BkAWFfWT6YEfyNnDY0UcRs2N9RHb+z65TsX1jvJJxLRDLRfz+rExfiZ cA1RJaF77kPOdA0eZapJIzPvAf97Zik+nzKLsqUPUSYaIzghV5rN6aR2AjXN5AYv TMQP41NwNQkxfO5I+NOssEB8IBH+DlAzg0LYXw8wNsAJc8o+DgEQjU8cxCqR0NgE SbpbJNF8tRXEJckZRC+Q7Gyn2J7VglmM/5VTFbBBwgIly2lcLADPVuX/Z6hZE3OH K7mhNWBu61vI5lU6u7q64ePeb63j+Ut/RR0tTPgjsLg0Qg0ue+6iZ66S9ZHEicbU wT4A/hjSImvZoQGGMrtUF5HGcaoMHGLGFgFc/Ouox8OQflntQBzuEx/gOQpPXcIT vdwITNW8/OGV3rgtmRO9mbdSZiAHPsydoTkIl+Ucod3nTrlEEOwgQARYO+2CfSRj sknndj26Kf+0n0tSv2d4JAEdEozp2ZPyfiAfpPXW74jOmOxeswUb3Kxx8YMwhCEl +s96rm1vtpNmJzXtuPV3eB0TydWMQ/3NXN6XOS7qEN/5y1AbQqKEoIyJOziBQMxe c9Eh/YSjsm4uw3Q0wHOI3s4hTwWfuBmwpIsANJVKrRbftPF58bMUBYU/44ReTtA8 iMsrqJpnSCcAyS8doWRY =s+gW -----END PGP SIGNATURE----- Merge tag 'devicetree-for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull devicetree updates from Rob Herring: - Rewrite of the unflattening code to avoid recursion and lessen the stack usage. - Rewrite of the phandle args parsing code to get rid of the fixed args size.

dt-bindings: pci: tegra: Update for per-lane PHYs
The XUSB pad controller allows PCIe lanes to be controlled individually, providing fine-grained control over their power state. Previous attempts at describing the XUSB pad controller in DT had erroneously assumed that all PCIe lanes were driven by the same PHY, and hence the PCI host controller would reference only a single PHY. Moving to a representation of per-lane PHYs requires that the operating system driver for the PCI host controller have access to the set of PHY devices that make up the connection of each root port in order to power up and down all of the lanes as necessary.

PCI: imx6: Add DT property for link gen, default to Gen1
Freescale has stated [1] that the LVDS clock source of the IMX6 does not pass the PCI Gen2 clock jitter test, therefore unless an external Gen2 compliant external clock source is present and supplied back to the IMX6 PCIe core via LVDS CLK1/CLK2 you can not claim Gen2 compliance. Add a DT property to specify Gen1 vs Gen2 and check this before allowing a Gen2 link. We default to Gen1 if the property is not present because at this time there are no IMX6 boards in mainline that 'input' a clock on LVDS CLK1/CLK2. In order to be Gen2 compliant on IMX6 you need to: - Have a Gen2 compliant external clock generator and route that clock back to either LVDS CLK1 or LVDS CLK2 as an input (see IMX6SX-SabreSD reference design). - Specify this clock in the PCIe node in the DT (i.e., IMX6QDL_CLK_LVDS1_IN or IMX6QDL_CLK_LVDS2_IN instead of IMX6QDL_CLK_LVDS1_GATE which configures it as a CLK output).

PCI: imx6: Add reset-gpio-active-high boolean property to DT
Currently the reset-gpio DT property which controls the PCI bus device reset signal defaults to active-low reset sequence (L=reset state, H=operation state) plus the code in reset function isn't GPIO polarity aware - it doesn't matter if the defined reset-gpio is active-low or active-high, it will always result into active-low reset sequence. I've tried to fix it properly and change the reset-gpio reset sequence to be polarity-aware, but this patch has been accepted and then reverted as it has introduced few backward incompatible issues: 1. Some DTBs, for example, imx6qdl-sabresd, don't define reset-gpio polarity correctly: reset-gpio = <&gpio7 12 0>; which means that it's defined as active-high, but in reality it's active-low; thus it wouldn't work without a DTS fix. 2. The logic in the reset function is inverted: gpio_set_value_cansleep(imx6_pcie->reset_gpio, 0) msleep(100); gpio_set_value_cansleep(imx6_pcie->reset_gpio, 1); so even if some of the i.MX6 boards had reset-gpio polarity defined correctly in their DTSes, they would stop working. As we can't break old DTBs, we can't fix them, so we need to introduce this new DT reset-gpio-active-high boolean property so we can support boards with active-high reset sequence. This active-high reset sequence is for example needed on Apalis SoMs, where GPIO1_IO28, used to PCIe reset is not connected directly to PERST# PCIe signal, but it's ORed with RESETBMCU coming off the PMIC, and thus is inverted, active-high.

PCI: thunder: Add driver for ThunderX-pass{1,2} on-chip devices
The cavium,pci-thunder-ecam devices are exactly ECAM-based PCI root complexes. These root complexes (loosely referred to as ECAM units in the hardware manuals) are used to access the Thunder on-chip devices. They are special in that all the BARs on devices behind these root complexes are at fixed addresses. Add a driver for these devices that synthesizes Enhanced Allocation (EA) capability entries for each BAR. Since this EA synthesis is needed for exactly two chip models, we can hard- code some assumptions about the device topology and the layout of the config space of specific DEVFNs in the driver.

ARM: DT updates for v4.4
As usual, this is the massive branch we have for each release.

DeviceTree updates for 4.4:
- DT binding doc consolidation moving similar bindings to common
locations. The majority of these are display related which were
scattered in video/, fb/, drm/, gpu/, and panel/ directories.
- Add new config option, CONFIG_OF_ALL_DTBS, to enable building all dtbs
in the tree for most arches with dts files (except powerpc for now).
- OF_IRQ=n fixes for user enabled CONFIG_OF.
- of_node_put ref counting fixes from Julia Lawall.
- Common DT binding for wakeup-source and deprecation of all similar
bindings.
- DT binding for PXA LCD controller.
- Allow ignoring failed PCI resource translations in order to ignore
64-bit addresses on non-LPAE 32-bit kernels.
- Support setting the NUMA node from DT instead of only from parent
device.
- Couple of earlycon DT parsing fixes for address and options.

Docs: dt: Add PCI MSI map bindings
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.

PCI: xgene: Add APM X-Gene v1 PCIe MSI/MSIX termination driver
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.

Documentation: DT bindings: add more Tegra chip compatible strings
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, ..."

PCI: keystone: Assume controller is already in RC mode
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.

PCI: designware: Parse bus-range property from devicetree
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.

PCI: keystone: Add TI Keystone PCIe driver
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.

powerpc: fsl_pci: Add forced PCI Agent enumeration
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.

PCI: designware: Split Exynos and i.MX bindings
The glue around the core designware IP is significantly different between the Exynos and i.MX implementation, which is reflected in the DT bindings. This changes the i.MX6 binding to reuse as much as possible from the common designware binding and removes old cruft. I removed the optional GPIOs with the following reasoning: - disable-gpio: endpoint specific GPIO, not currently wired up in any code. Should be handled by the PCI device driver, not the host controller driver. - wake-up-gpio: same as above. - power-on-gpio: No user in any upstream DT. This should be handled by a regulator which shouldn't be controlled by the host driver, but rather by the PCI device driver.

PCI: generic: Add generic PCI host controller driver
Add support for a generic PCI host controller, such as a firmware-initialised device with static windows or an emulation by something such as kvmtool. The controller itself has no configuration registers and has its address spaces described entirely by the device-tree (using the bindings from ePAPR). Both CAM and ECAM are supported for Config Space accesses. Add corresponding documentation for the DT binding.

ARM: SoC cleanups for 3.14
This is the branch where we usually queue up cleanup efforts, moving
drivers out of the architecture directory, header file restructuring,
etc. Sometimes they tangle with new development so it's hard to keep it
strictly to cleanups.
Some of the things included in this branch are:
* Atmel SAMA5 conversion to common clock
* Reset framework conversion for tegra platforms
- Some of this depends on tegra clock driver reworks that are shared with Mike
Turquette's clk tree.
* Tegra DMA refactoring, which are shared branches with the DMA tree.
* Removal of some header files on exynos to prepare for multiplatform

ARM: tegra: document reset properties in DT bindings
Update all the Tegra DT bindings to require resets/reset-names properties where the HW module has reset inputs. Remove any entries from clocks or clock-names that were only required to identify reset inputs, rather than referring to real clocks. This is a DT-ABI-incompatible change. It is the first of two changes required for me to consider the Tegra DT bindings as stable, the other being conversion to the common DMA DT bindings.

PCI: mvebu: add support for MSI
This commit adds support for Message Signaled Interrupts in the Marvell PCIe host controller. The work is very simple: it simply gets a reference to the msi_chip associated to the PCIe controller thanks to the msi-parent DT property, and stores this reference in the pci_bus structure.

ARM: SoC platform changes for 3.12
This branch contains mostly additions and changes to platform enablement
and SoC-level drivers. Since there's sometimes a dependency on device-tree
changes, there's also a fair amount of those in this branch.
Pieces worth mentioning are:
- Mbus driver for Marvell platforms, allowing kernel configuration
and resource allocation of on-chip peripherals.
- Enablement of the mbus infrastructure from Marvell PCI-e drivers.
- Preparation of MSI support for Marvell platforms.
- Addition of new PCI-e host controller driver for Tegra platforms
- Some churn caused by sharing of macro names between i.MX 6Q and 6DL
platforms in the device tree sources and header files.
- Various suspend/PM updates for Tegra, including LP1 support.
- Versatile Express support for MCPM, part of big little support.
- Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
- OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
The code that touches other architectures are patches moving
MSI arch-specific functions over to weak symbols and removal of
ARCH_SUPPORTS_MSI, acked by PCI maintainers.

MIPS: Add driver for the built-in PCI controller of the RT3883 SoC
The Ralink RT3883 SoCs have a built-in PCI Host Controller device. The patch adds a platform driver and device tree binding documentation for that.

ARM: tegra: core SoC enhancements for 3.12
This branch includes a number of enhancements to core SoC support for Tegra devices. The major new features are: * Adds a new CPU-power-gated cpuidle state for Tegra114. * Adds initial system suspend support for Tegra114, initially supporting just CPU-power-gating during suspend. * Adds "LP1" suspend mode support for all of Tegra20/30/114. This mode both gates CPU power, and places the DRAM into self-refresh mode. * A new DT-driven PCIe driver to Tegra20/30. The driver is also moved from arch/arm/mach-tegra/ to drivers/pci/host/.

ARM: integrator: basic PCIv3 device tree support
This registers the memory ranges for I/O, non-prefetched and prefetched memory and configuration space for the PCIv3 bridge and let us fetch these basic memory resources from the device tree in the device tree boot path. Remove the stepping stone platform device. This is an either/or approach - the platform data path is mutually exclusive to the plain platform data path and provided addresses from the device tree have to be correct. This adds the interrupt-map property to the PCIv3 DTS file and makes the bridge obtain mappings from the device tree.

pci: PCIe driver for Marvell Armada 370/XP systems
This driver implements the support for the PCIe interfaces on the Marvell Armada 370/XP ARM SoCs. In the future, it might be extended to cover earlier families of Marvell SoCs, such as Dove, Orion and Kirkwood. The driver implements the hw_pci operations needed by the core ARM PCI code to setup PCI devices and get their corresponding IRQs, and the pci_ops operations that are used by the PCI core to read/write the configuration space of PCI devices. Since the PCIe interfaces of Marvell SoCs are completely separate and not linked together in a bus, this driver sets up an emulated PCI host bridge, with one PCI-to-PCI bridge as child for each hardware PCIe interface. In addition, this driver enumerates the different PCIe slots, and for those having a device plugged in, it sets up the necessary address decoding windows, using the mvebu-mbus driver.
