  • 0ab66b3c3   regulator: max77620: Initialize values for DT properties ... Browse Code »

    If regulator DT node doesn't exist, its of_parse_cb callback
    function isn't called. Then all values for DT properties are
    filled with zero. This leads to wrong register update for
    FPS and POK settings.

  • 634dc7abc   regulator: max77620-regulator: constify regulator_ops structure ... Browse Code »

    Declare regulator_ops structure as const as it is only stored in the ops
    field of a regulator_desc structure. This field is of type const, so
    regulator_ops structures having this property can be made const too.

  • 383d0fca7   regulator: max77620: add support to configure MPOK ... Browse Code »

    Adding support to configure regulator POK mapping bit
    to control nRST_IO and GPIO1 POK function.
    In tegra based platform which uses MAX20024 pmic, when
    some of regulators are configured FPS_NONE(flexible power sequencer)
    causes PMIC GPIO1 to go low which lead to various other rails turning off,
    to avoid this MPOK bit of those regulators need to be set to 0
    so that PMIC GPIO1 will not go low.

  • 91ff811f3   regulator: max77620: check for valid regulator info ... Browse Code »

    SD4 regulator is not registered with regulator core
    framework in probe as there is no support in MAX77620 PMIC,
    removing SD4 entry from MAX77620 regulator information list
    and checking for valid regulator information data before
    configuring FPS source and FPS power up/down period to avoid
    NULL pointer exception if regulator not registered with core.

  • 5aa43599d   regulator: max77620: Add support for device specific ramp rate setting ... Browse Code »

    Maxim advertised the ramp rate of the rail with some recommended
    design specification like output capacitance of rail should be
    2.2uF. This make sure that current change in the rail is within
    maximum current limit and hence meet the advertised ramp rate.

    If there is variation in design which causes the rail current to
    change more that maximum current limit then device applies the
    current limit. In this case, ramp rate is different than advertised
    ramp rate.

    Add device specific settings for ramp rate which need to be configure
    on device register when measure ramp rate on platform is deviated from
    advertised ramp rate. In this case, all delay time calculation for
    voltage change is done with measured ramp rate and device ramp rate
    is used for configuring the device register.

    If measured ramp rate in the platform is same as advertised ramp rate
    then regulator-ramp-delay is used for the device register configuration
    and ramp time calculation for voltage change.

  • 5b1c20286   regulator: max77620: add regulator driver for max77620/max20024 ... Browse Code »

    MAXIM Semiconductor's PMIC, MAX77620 and MAX20024 have the
    multiple DCDC and LDOs. This supplies the power to different
    components of the system.
    Also these rails has configuration for ramp time, flexible
    power sequence, slew rate etc.

    Add regulator driver to access these rails via regulator APIs.
