  • 62e59c4e6   clk: Remove io.h from clk-provider.h ... Browse Code »

    Now that we've gotten rid of clk_readl() we can remove io.h from the
    clk-provider header and push out the io.h include to any code that isn't
    already including the io.h header but using things like readl/writel,
    etc.

    Found with this grep:

    I also reordered a couple includes when they weren't alphabetical and
    removed clk.h from kona, replacing it with clk-provider.h because
    that driver doesn't use clk consumer APIs.

  • d1558dfd9   ARM: rockchip: Force CONFIG_PM on Rockchip systems ... Browse Code »

    A number of the Rockchip-specific drivers (IOMMU, display controllers)
    are now assuming that CONFIG_PM is set, and may completely misbehave
    if that's not the case.

    Since there is hardly any reason for this configuration option not
    to be selected anyway, let's require it (in the same way Tegra already
    does).

  • 4965a6878   arch: define the ARCH_DMA_ADDR_T_64BIT config symbol in lib/Kconfig ... Browse Code »

    Define this symbol if the architecture either uses 64-bit pointers or the
    PHYS_ADDR_T_64BIT is set. This covers 95% of the old arch magic. We only
    need an additional select for Xen on ARM (why anyway?), and we now always
    set ARCH_DMA_ADDR_T_64BIT on mips boards with 64-bit physical addressing
    instead of only doing it when highmem is set.

    Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
    reset lines") started to transition the reset control request API calls
    to explicitly state whether the driver needs exclusive or shared reset
    control behavior. Convert all drivers requesting exclusive resets to the
    explicit API call so the temporary transition helpers can be removed.

    No functional changes.

    After patch "of/platform: Add common method to populate default bus",
    it is possible for arch code to remove unnecessary callers of
    of_platform_populate with default match table.

  • 5c34a4e89   ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB ... Browse Code »

    This replaces:

    - "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
    now be selected directly.

    - "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
    is now selectable by everyone, so we need not declare our
    intent to select it.

    When ordering the symbols the following rationale was used:
    if the selects were in alphabetical order, I moved select GPIOLIB
    to be in alphabetical order, but if the selects were not
    maintained in alphabetical order, I just replaced
    "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

    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"

  • e32465429   ARM: use "depends on" for SoC configs instead of "if" after prompt ... Browse Code »

    Many ARM sub-architectures use prompts followed by "if" conditional,
    but it is wrong.

    Please notice the difference between

    config ARCH_FOO
    bool "Foo SoCs" if ARCH_MULTI_V7

    and

    config ARCH_FOO
    bool "Foo SoCs"
    depends on ARCH_MULTI_V7

    These two are *not* equivalent!

    In the former statement, it is not ARCH_FOO, but its prompt that
    depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO
    is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
    not unmet dependency, Kconfig never warns. This is probably not what
    you want.

    The former should be used only when you need to do so, and you really
    understand what you are doing. (In most cases, it should be wrong!)

    For enabling/disabling sub-architectures, the latter is always correct.

    As a good side effect, this commit fixes some entries over 80 columns
    (mach-imx, mach-integrator, mach-mbevu).

    [Arnd: I note that there is not really a bug here, according to
    the discussion that followed, but I can see value in being consistent
    and in making the lines shorter]

    These smp_operations structures are not over-written, so add "const"
    qualifier and replace __initdata with __initconst.

    Also, add "static" where it is possible.

  • 9def7ccfe   ARM: rockchip: add support smp for rk3036 ... Browse Code »

    The dual-core Cortex A7 rk3036 is a bit special in that it does not allow
    to control the actual powerdomain of the cpu cores, while the rest of the
    smp-bringup like reset control and entry address handling stays the same.
    Its bigger sibling, the quad-core rk3128 again allows powerdomain control.

    So allow that case by introducing a separate smp-enable-method, that simply
    disables powerdomain handling in the common code.
