  • 9f7e25edb   regulator: core: Handle full constraints systems when resolving supplies ... Browse Code »

    When resolving device supplies if we fail to look up the regulator we
    substitute in the dummy supply instead if the system has fully specified
    constraints. When resolving supplies for regulators we do not have the
    equivalent code and instead just directly use the regulator_dev_lookup()
    result causing spurious failures.

    This does not affect DT systems since we are able to detect missing
    mappings directly as part of regulator_dev_lookup() and so have appropriate
    handling in the DT specific code.

  • 322dfa640   regulator: 88pm800: fix LDO vsel_mask value ... Browse Code »

    As per datasheet,
    Except LDO2, all other LDO's use bit [3:0] for VOUT select.

    Current code uses wrong mask value of 0x1f, So this patch
    fixes it to use 0xf.

    Pull implicit module.h fixes from Paul Gortmaker:
    "Fix up implicit users that will break later.

    The files changed here are simply modular source files that are
    implicitly relying on being present. We fix them up now,
    so that we can decouple some of the module related init code from the
    core init code in the future.

    The addition of the module.h include to several files here is also a
    no-op from a code generation point of view, else there would already
    be compile issues with these files today.

    There may be lots more implicit includes of in tree, but
    these are the ones that extensive build test coverage has shown that
    must be fixed in order to avoid build breakage fallout for the pending
    module.h init.h code relocation we desire to complete"

    Pull sound updates from Takashi Iwai:
    "It was a busy development cycle at this time, as you can see a wide
    range of changes in diffstat. There are no big changes but many
    refactoring and improvements. Here we go some highlights:

    ALSA core:
    - Procfs codes were cleaned up to use seq_file
    - Procfs can be opt out via Kconfig (only for EXPERT)
    - Two types of jack API were unified finally; now both kctl and input
    jack devs are handled via a single function call.

    HD-audio:
    - Continued code restructuring for the future ASoC driver; now HDA
    controller driver is split to a core helper module.
    - Preliminary codes for Skylake audio support in HDA core.
    - Proper i915 gfx power well management for SKL & co
    - Enabled runtime PM as default for Intel HDMI/DP codecs
    - Newer Tegra chip supports
    - More quirks for Dell headsets, Alienware (with CA0132), etc.
    - A couple of DRM ELD helper API functions

    ASoC:
    - Support for loading ASoC topology maps from firmware, intended to
    be used to allow self-describing DSP firmware images to be built
    which can map controls added by the DSP to userspace without the
    kernel needing to know about individual DSP firmwares
    - Lots of refactoring to avoid direct access to snd_soc_codec where
    it's not needed supporting future refactoring
    - Big refactoring, cleanup and enhancement for the Wolfson ADSP
    driver
    - Cleanup series for TI TAS2552 and R-CAR drivers
    - Fixes and improvements on RT56xx codecs
    - Support for TI TAS571x power amplifiers
    - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs
    - Support for x86 systems with RT5650 and Qualcomm Storm
    - Support for Mediatek AFE (Audio Front End) unit
    - Other various small fixes to ASoC codec drivers

    Firewire:
    - Enhanced to allow non-blocking streams to use timestamp
    synchronization
    - Improve support for DM1500 and BeBoBv3

    Misc:
    - Cleanup of old pci API functions over all PCI sound drivers
    - Fix long-standing regression of the old powermac i2c setup"

  • 32c848e33   regulator: s2mps11: Fix GPIO suspend enable shift wrapping bug ... Browse Code »

    Status of enabling suspend mode for regulator was stored in bitmap-like
    long integer.

    However since adding support for S2MPU02 the number of regulators
    exceeded 32 so on devices with more than 32 regulators (S2MPU02 and
    S2MPS13) overflow happens when shifting the bit. This could lead to
    enabling suspend mode for completely different regulator than intended
    or to switching different regulator to other mode (e.g. from always
    enabled to controlled by PWRHOLD pin). Both cases could result in larger
    energy usage and issues when suspending to RAM.

  • ff268b56c   regulator: core: Don't spew backtraces on duplicate sysfs ... Browse Code »

    We don't consider a failure to add the sysfs node as a problem,
    so use sysfs_create_link_nowarn() so that we don't print a
    backtrace when duplicated files exist. Also, downgrade the printk
    message to a debug statement so that we're quiet here. This
    allows multiple drivers to request a CPU's regulator so that
    CPUfreq and AVSish drivers can coexist.

    Using the driver for the internal regulator to also enable/disable
    the codec internal clock frequency controller is an unexpected
    side-effect for a regulator, and also means that the core clocks
    won't be changed as expected if an external regulator is used to
    power the codec.

    The DVFS is now handled by the codec driver so can be removed from
    the LDO1 driver.

  • d87aef916   regulator: da9063: Fix up irq leak ... Browse Code »

    Current code does not set regulators->irq_ldo_lim and regulators->irq_uvov,
    so it actually calls free_irq(0, regulators) twice in remove() but does not
    free the irq actually used.

    Convert to use devm_request_threaded_irq instead and then we don't need to
    take care the clean up irq so remove irq_ldo_lim and irq_uvov from
    struct da9063_regulators. Note, regulators->irq_uvov is not used at all in
    current code.

    There is a slightly change in this patch, it will return error in probe()
    if devm_request_threaded_irq fails. If the irq is optional, it should be
    fine to allow platform_get_irq_byname fails. But current code does not
    allow platform_get_irq_byname fails. So I think the reason to allow
    request irq failure is just because the irq leak.
