  • 0792a2c8e   macintosh: Use common code to access RTC ... Browse Code »

    Now that the 68k Mac port has adopted the via-pmu driver, the same RTC
    code can be shared between m68k and powerpc. Replace duplicated code in
    arch/powerpc and arch/m68k with common RTC accessors for Cuda and PMU.

    Drop the problematic WARN_ON which was introduced in commit 22db552b50fa
    ("powerpc/powermac: Fix rtc read/write functions").

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • 0094f2cdc   [POWERPC] Fix for via-pmu based backlight control ... Browse Code »

    This fixes a few issues with via-pmu based backlight control.

    First, it fixes a sign problem with the setup of the backlight
    curve since the `range' value there -can- (and will) go negative.

    Then, it reworks the interaction between this and the via-pmu sleep
    code to properly restore backlight on wakeup from sleep.

  • e120e8d03   [POWERPC] Fix undefined reference to device_power_up/resume ... Browse Code »

    Current Linus tree fails to link on pmac32:

    drivers/built-in.o: In function `pmac_wakeup_devices':
    via-pmu.c:(.text+0x5bab4): undefined reference to `device_power_up'
    via-pmu.c:(.text+0x5bb08): undefined reference to `device_resume'

    via-pmu.c:(.text+0x5c27c): undefined reference to `device_resume'
    make[1]: *** [.tmp_vmlinux1] Error 1

    changing CONFIG_PM > CONFIG_PM_SLEEP leads to:

    drivers/built-in.o: In function `pmu_led_set':
    via-pmu-led.c:(.text+0x5cdca): undefined reference to `pmu_sys_suspended'

    So change even more places from PM to PM_SLEEP to allow linking.

  • f596575e8   [POWERPC] via-pmu: remove LED sleep notifier ... Browse Code »

    The generic LED code now makes sure that suspended devices don't blink,
    so we no longer need to do it ourselves. For the suspend to disk case,
    however, we need to make sure that we don't blink if the PMU sysdev
    was suspended before the LED device.

  • 4b755999d   [PATCH] powermac: More powermac backlight fixes ... Browse Code »

    This patch fixes several problems:
    - The legacy backlight value might be set at interrupt time. Introduced
    a worker to prevent it from directly calling the backlight code.
    - via-pmu allows the backlight to be grabbed, in which case we need to
    prevent other kernel code from changing the brightness.
    - Don't send PMU requests in via-pmu-backlight when the machine is about
    to sleep or waking up.
    - More Kconfig fixes.

    This patch contains a total rewrite of the backlight infrastructure for
    portable Apple computers. Backward compatibility is retained. A sysfs
    interface allows userland to control the brightness with more steps than
    before. Userland is allowed to upload a brightness curve for different
    monitors, similar to Mac OS X.

  • 730745a5c   [PATCH] 1/5 powerpc: Rework PowerMac i2c part 1 ... Browse Code »

    This is the first part of a rework of the PowerMac i2c code. It
    completely reworks the "low_i2c" layer. It is now more flexible,
    supports KeyWest, SMU and PMU i2c busses, and provides functions to
    match device nodes to i2c busses and adapters.

    This patch also extends & fix some bugs in the SMU driver related to i2c
    support and removes the clock spreading hacks from the pmac feature code
    rather than adapting them to the new API since they'll be replaced by
    the platform function code completely in patch 3/5

    split into CONFIG_PMAC_MEDIABAY for the actual hotswap bay that some
    powerbooks have, CONFIG_PM for power management related code, and just left
    out of any CONFIG_* option for some generally useful stuff that can be used
    on non-laptops as well.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
