  • On ARM64, the mtk-pmic-wrap driver causes a harmless warning:

    mtk-pmic-wrap.c:1062:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
    mtk-pmic-wrap.c:1074:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
    mtk-pmic-wrap.c:1086:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
    .int_en_all = ~(BIT(31) | BIT(1)),

    The problem is that the result of the BIT() macro is an 'unsigned long',
    so taking the bitwise NOT operation of that results in an integer
    with the upper 32 bits all set and that cannot be assigned to a
    'u32' variable without loss of information.

    This is harmless because we were never interested in the upper bits
    here anyway, so we can shut up the warning by adding a simple cast
    to 'u32'.

  • Pull ARM SoC driver updates from Arnd Bergmann:
    "Driver updates for ARM SoCs, these contain various things that touch
    the drivers/ directory but got merged through arm-soc for practical
    reasons.

    For the most part, this is now related to power management
    controllers, which have not yet been abstracted into a separate
    subsystem, and typically require some code in drivers/soc or arch/arm
    to control the power domains.

    Another large chunk here is a rework of the NVIDIA Tegra USB3.0
    support, which was surprisingly tricky and took a long time to get
    done.

    Finally, reset controller handling as always gets merged through here
    as well"

  • Pull ARM DT updates from Arnd Bergmann:
    "These are all the updates to device tree files for 32-bit platforms,
    which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
    changesets, 450 files changed, 23340 insertions, 5216 deletions.

    The three platforms that are added with the "soc" branch are here as
    well, and we add some related machine files:

    - For Aspeed AST2400/AST2500, we get the evaluation platform and the
    Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
    - For Oxnas 810SE, the Western Digital "My Book World Edition" is
    added as the only platform at the moment.
    - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7) are
    supported

    On the ARM Realview development platform, we now support all machines
    with device tree, previously only the board files were supported,
    which in turn will likely be removed soon.

    Qualcomm IPQ4019 is the second generation ARM based "Internet
    Processor", following the IPQ806x that is used in many high-end WiFi
    routers. This one integrates two ath10k wifi radios that were
    previously on separate chips.

    Other boards that got added for existing chips are:

    Ti OMAP family:
    - Amazon Kindle Fire, first generation, tablet and ebook reader
    - OnRISC Baltos iR 2110 and 3220 embedded industrial PCs

  • Pull ARM SoC cleanups and fixes from Arnd Bergmann:
    "Traditionally we've had two separate branches for cleanups and
    non-critical bug fixes, but both of these got smaller with each
    release and the differences are rather unclear now, so it seems more
    appropriate to have a combined branch.

    The most notable change is for OMAP, which gets a small rework to
    simplify handling of the AUXDATA mechanism used on machines that are
    not completely DT based yet, along with other work that is used as
    preparation for dropping the legacy board files"

  • Pull GPIO updates from Linus Walleij:
    "This is the bulk of GPIO changes for kernel cycle v4.7:

    Core infrastructural changes:

    - Support for natively single-ended GPIO driver stages.

    This means that if the hardware has registers to configure open
    drain or open source configuration, we use that rather than (as we
    did before) try to emulate it by switching the line to an input to
    get high impedance.

    This is also documented throughly in Documentation/gpio/driver.txt
    for those of you who did not understand one word of what I just
    wrote.

    - Start to do away with the unnecessarily complex and unitelligible
    ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another
    evolutional artifact from the time when the GPIO subsystem was
    unmaintained.

    Archs can now just select GPIOLIB and be done with it, cleanups to
    arches will trickle in for the next kernel. Some minor archs ACKed
    the changes immediately so these are included in this pull request.

    - Advancing the use of the data pointer inside the GPIO device for
    storing driver data by switching the PowerPC, Super-H Unicore and
    a few other subarches or subsystem drivers in ALSA SoC, Input,
    serial, SSB, staging etc to use it.

    - The initialization now reads the input/output state of the GPIO
    lines, so that each GPIO descriptor knows - if this callback is
    implemented - whether the line is input or output. This also
    reflects nicely in userspace "lsgpio".

    - It is now possible to name GPIO producer names, line names, from
    the device tree. (Platform data has been supported for a while).
    I bet we will get a similar mechanism for ACPI one of those days.
    This makes is possible to get sensible producer names for e.g.
    GPIO rails in "lsgpio" in userspace.

    New drivers:

    - New driver for the Loongson1.

    - The XLP driver now supports Broadcom Vulcan ARM64.

    - The IT87 driver now supports IT8620 and IT8628.

    - The PCA953X driver now supports Galileo Gen2.

    Driver improvements:

    - MCP23S08 was switched to use the gpiolib irqchip helpers and now
    also suppors level-triggered interrupts.

    - 74x164 and RCAR now supports the .set_multiple() callback

    - AMDPT was converted to use generic GPIO.

    - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
    support the new single ended callback for open drain and in some
    cases open source.

    - Implement the .get_direction() callback for a few more drivers like
    PL061, Xgene.

    Cleanups:

    - Paul Gortmaker combed through the drivers and de-modularized those
    who are not really modules.

    - Move the GPIO poweroff DT bindings to the power subdir where they
    belong.

    - Rename gpio-generic.c to gpio-mmio.c, which is much more to the
    point. That's what it is handling, nothing more, nothing less"

  • 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
    and Vince Hsu .

    also part of the CPG/MSSR Clock Domain.
    On all R-Car SoCs, devices in the "always-on" PM Domain are part of the
    Clock Domain served by the CPG/MSSR or CPG/MSTP driver.

    Hook up the CPG/MSTP or CPG/MSSR Clock Domain attach/detach callbacks to
    enable power management using module clocks. Which callback to hook up
    depends on the presence of device nodes compatible with
    "renesas,cpg-mstp-clocks". This clears the path for a future migration
    from the CPG/MSTP to the CPG/MSSR driver on R-Car H1 and
    Gen2.

  • The newly added code for the SoC bus fails to link if the
    bus is not built:

    drivers/soc/built-in.o: In function `brcmstb_soc_device_init':
    :(.init.text+0x110): undefined reference to `soc_device_register'

    This adds a 'select' statement to avoid the error.

  • As of commit b12ff41658171f53 ("ARM: shmobile: r8a7779: Remove legacy PM
    Domain remainings"), rcar_sysc_power_is_off() is no longer used from
    SoC-specific code.

  • Populate the SYSC PM domains from DT, based on the presence of a device
    node for the System Controller. The actual power area hiearchy, and
    features of specific areas are obtained from tables in the C code.

    The SYSCIER and SYSCIMR register values are derived from the power areas
    present, which will help to get rid of the hardcoded values in R-Car H1
    and R-Car Gen2 platform code later.

    Initialization is done from an early_initcall(), to make sure the PM
    Domains are initialized before secondary CPU bringup.

  • Move the pm-rcar driver from arch/arm/mach-shmobile/ to
    drivers/soc/renesas/, and its header file to include/linux/soc/renesas/,
    so it can be shared between arm32 (R-Car H1 and Gen2) and arm64 (R-Car
    Gen3). Rename it to rcar-sysc as it's really a driver for the R-Car
    System Controller (SYSC).

    Kill the intermediate PM_RCAR config symbol, as it's not user
    configurable anymore, and to prepare for SoC-specific make rules.

    Add the missing #include to rcar-sysc.h, which was
    exposed by different include order.
