Yuriy Kolerov 6f0310a126 ARCv2: IDU-intc: Use build registers for getting numbers of interrupts
This enhancement is needed to allow masking all available common interrupts
in IDU interrupt controller in boot time since the kernel can
discover a number of them from the build register. Also now there
is no need to specify in device tree a list of used core interrupts
by IDU. E.g. before:

    idu_intc: idu-interrupt-controller {
        compatible = "snps,archs-idu-intc";
        interrupt-controller;
        interrupt-parent = <&core_intc>;
        #interrupt-cells = <2>;
        interrupts = <24 25 26 27 28 29 30 31>;
    };

and after:

    idu_intc: idu-interrupt-controller {
        compatible = "snps,archs-idu-intc";
        interrupt-controller;
        interrupt-parent = <&core_intc>;
        #interrupt-cells = <2>;
    };

Linus Torvalds de399813b5 powerpc updates for 4.10
Highlights include:
 
  - Support for the kexec_file_load() syscall, which is a prereq for secure and
    trusted boot.
 
  - Prevent kernel execution of userspace on P9 Radix (similar to SMEP/PXN).
 
  - Sort the exception tables at build time, to save time at boot, and store
    them as relative offsets to save space in the kernel image & memory.
 
  - Allow building the kernel with thin archives, which should allow us to build
    an allyesconfig once some other fixes land.
 
  - Build fixes to allow us to correctly rebuild when changing the kernel endian
    from big to little or vice versa.
 
  - Plumbing so that we can avoid doing a full mm TLB flush on P9 Radix.
 
  - Initial stack protector support (-fstack-protector).
 
  - Support for dumping the radix (aka. Linux) and hash page tables via debugfs.
 
  - Fix an oops in cxl coredump generation when cxl_get_fd() is used.
 
  - Freescale updates from Scott: "Highlights include 8xx hugepage support,
    qbman fixes/cleanup, device tree updates, and some misc cleanup."
 
  - Many and varied fixes and minor enhancements as always.

Linus Torvalds 991688bfc6 ARM: SoC driver updates for v4.10
Driver updates for ARM SoCs, including a couple of newly added drivers:
 
 - A new driver for the power management controller on TI Keystone
 - Support for the prerelease "SCPI" firmware protocol that ended up
   being shipped by Amlogic in their GXBB SoC.
 - A soc_device can now be matched using a glob from inside the
   kernel, when another driver wants to know the specific chip
   it is running on and cannot find out from DT, firmware or hardware.
 - Renesas SoCs now support identification through the soc_device
   interface, both in user space and kernel.
 - Renesas r8a7743 and r8a7745 gain support for their system controller
 - A new checking module for the ARM "PSCI" (not to be confused
   with "SCPI" mentioned above) firmware interface.
 - A new driver for the Tegra GMI memory interface
 - Support for the Tegra firmware interfaces with their
   power management controllers
 
 As usual, the updates for the reset controller framework are merged
 here, as they tend to touch multiple SoCs as well, including a new
 driver for the Oxford (now Broadcom) OX820 chip and the Tegra
 bpmp interface.
 
 The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
 Rockchips SoCs see some further updates.
 
 Conflicts:
 - ARCH_RENESAS now selects SOC_BUS, but no longer needs GPIOLIB
 - drivers/soc/renesas/Makefile: multiple files got added, keep
   all in logical sorting

Noam Camus 09dcd1958b soc: Support for NPS HW scheduling
This new header file is for NPS400 SoC (part of ARC architecture).
The header file includes macros for save/restore of HW scheduling.
The control of HW scheduling is achieved by writing core registers.
This code was moved from arc/plat-eznps so it can be used
from drivers/clocksource/, available only for CONFIG_EZNPS_MTM_EXT.

Thierry Reding 983de5f971 firmware: tegra: Add BPMP support
The Boot and Power Management Processor (BPMP) is a co-processor found
on Tegra SoCs. It is designed to handle the early stages of the boot
process and offload power management tasks (such as clocks, resets,
powergates, ...) as well as system control services.

Compared to the ARM SCPI, the services provided by BPMP are message-
based rather than method-based. The BPMP firmware driver provides the
services to transmit data to and receive data from the BPMP. Users can
also register a Message ReQuest (MRQ), for which a service routine will
be run when a corresponding event is received from the firmware.

A set of messages, called the BPMP ABI, are specified for a number of
different services provided by the BPMP (such as clocks or resets).

Thierry Reding ca791d7f42 firmware: tegra: Add IVC library
The Inter-VM communication (IVC) is a communication protocol which is
designed for interprocessor communication (IPC) or the communication
between the hypervisor and the virtual machine with a guest OS.

Message channels are used to communicate between processors. They are
backed by DRAM or SRAM, so care must be taken to maintain coherence of
data.

The IVC library maintains memory-based descriptors for the transmission
and reception channels as well as the data coherence of the counter and
payload. Clients, such as the driver for the BPMP firmware, can use the
library to exchange messages with remote processors.

Laxman Dewangan 21b4991051 soc/tegra: pmc: Add I/O pad voltage support
I/O pins on Tegra SoCs are grouped into so-called I/O pads. Each such
pad can be used to control the common voltage signal level and power
state of the pins in the given pad.

I/O pads can be powered down even if the system is active, which can
save power from that I/O interface. For SoC generations prior to
Tegra124 the I/O pad voltage is automatically detected and hence the
system software doesn't need to configure it. However, starting with
Tegra210 the detection logic has been removed, so explicit control of
the I/O pad voltage by system software is required.

Linus Torvalds 5617c122e6 The core clk framework changes are small again. They're mostly minor fixes
that weren't causing enough problems (or any problems when we're just
 clarifying things) to warrant sending outside the merge window. The
 majority of changes are in drivers for various SoCs. Full details
 are in the logs, but here's the summary.
 
 Core:
 
  - Better support for DeviceTree overlays with the addition of the
    CLK_OF_DECLARE_DRIVER macro. Now we won't probe a clk driver
    for a device node that matched during of_clk_init(), unless
    the driver uses CLK_OF_DECLARE_DRIVER instead of CLK_OF_DECLARE.
    This allows overlays to work cleanly for drivers that must probe
    before the device model is ready, and also after it's ready
    when an overlay is loaded.
 
  - Clarification in the code around how clk_hw pointers are returned
    from of clk providers
 
  - Proper migration of prepare/enable counts to parents when the
    clk tree is constructed
 
 New Drivers:
 
  - Socionext's UniPhier SoCs
  - Loongson1C
  - ZTE ZX296718
  - Qualcomm MDM9615
  - Amlogic GXBB AO clocks and resets
  - Broadcom BCM53573 ILP
  - Maxim MAX77620
 
 Updates:
 
  - Four Allwinner SoCs are migrated to the new style clk driver (A31, A31s,
    A23 and A33)
  - Exynos 5xxx audio and DRAM clks
  - Loongson1B AC97, DMA and NAND clks
  - Rockchip DDR clks and rk3399 driver tweaks
  - Renesas R-Car M3-W (r8a7796) SoC SDHI interface and Watchdog timer clks
  - Renasas R-Car H3 and M3-W CMT clks and RAVB+Thermal clks for M3-W
  - Amlogic GXBB MMC gate clks
  - at91 sama5d4 sckc
  - Removal of STiH415 and STiH416 clk support as the SoC is being removed
  - Rework of STiH4xx clk support for new style bindings
  - Continuation of driver migration to clk_hw based registration APIs
  - xgene PMD support

Claudiu Manoil c535e923bb soc/fsl: Introduce DPAA 1.x QMan device driver
This driver enables the Freescale DPAA 1.x Queue Manager block.
QMan is a hardware accelerator that manages frame queues.  It allows
CPUs and other accelerators connected to the SoC datapath to enqueue
and dequeue ethernet frames, thus providing the infrastructure for
data exchange among CPUs and datapath accelerators.

Wenyou Yang 2e2aa1bc7e usb: ohci-at91: Forcibly suspend ports while USB suspend
The usb controller does not manage correctly the suspend mode for
the ehci. In echi mode, there is no way to suspend without any
device connected to it. This is why this specific control is added
to fix this issue. Since the suspend mode works in ohci mode, this
specific control works by suspend the usb controller in ohci mode.

This specific control is by setting the SUSPEND_A/B/C fields of
SFR_OHCIICR(OHCI Interrupt Configuration Register) in the SFR
while the OHCI USB suspend.

This set operation must be done before the USB clock disabled,
clear operation after the USB clock enabled.

The i.MX6 Q/DL has an erratum (ERR006687) that prevents the FEC from
waking the CPUs when they are in wait(unclocked) state. As the hardware
workaround isn't applicable to all boards, disable the deeper idle state
when the workaround isn't present and the FEC is in use.

This allows to safely run a kernel with CPUidle enabled on all i.MX6

Arnd Bergmann b7dcc6d01f soc/tegra: Add generic PM domain support
Implements generic PM domain support on top of the existing Tegra power-
 gate API. Drivers are thus allowed to move away from the Tegra-specific
 API and towards using generic power domains directly.

Arnd Bergmann 4ace926172 phy: tegra: Changes for v4.7-rc1
This set of patches adds support for the Tegra XUSB pad controller. The
 controller provides a set of pads (lanes) that are used for I/O by other
 IP blocks within Tegra SoCs (PCIe, SATA and XUSB).

Jon Hunter a38045121b soc/tegra: pmc: Add generic PM domain support
Adds generic PM domain support to the PMC driver where the PM domains
are populated from device-tree and the PM domain consumer devices are
bound to their relevant PM domains via device-tree as well.

Update the tegra_powergate_sequence_power_up() API so that internally
it calls the same tegra_powergate_xxx functions that are used by the
Tegra generic PM domain code for consistency.

To ensure that the Tegra power domains (a.k.a. powergates) cannot be
controlled via both the legacy tegra_powergate_xxx functions as well
as the generic PM domain framework, add a bit map for available
powergates that can be controlled via the legacy powergate functions.

Move the majority of the tegra_powergate_remove_clamping() function
to a sub-function, so that this can be used by both the legacy and
generic power domain code.

This is based upon work by Thierry Reding <treding@nvidia.com>
and Vince Hsu <vinceh@nvidia.com>.

Thierry Reding 87d66f2806 phy: tegra: Add Tegra210 support
Add support for the XUSB pad controller found on Tegra210 SoCs. The
hardware is roughly the same, but some of the registers have been moved
around and the number and type of supported pads has changed.
