  • 2468f0d51   regulator: lp8788-ldo: Pass descriptor instead of GPIO number ... Browse Code »

    Instead of passing a global GPIO number, pass a descriptor looked
    up with the standard devm_gpiod_get_index_optional() call.

    This driver has supported passing a LDO enable GPIO for years,
    yet this facility has never been put to use in the upstream kernel.
    If someone desires to put in place GPIO control for the LDOs,
    this can be done by adding a GPIO descriptor table in the MFD
    nexus in drivers/mfd/lp8788.c for the LDO device when spawning the
    MFD children, or using a board file.

  • c5a51053c   backlight: add new lp8788 backlight driver ... Browse Code »

    TI LP8788 PMU supports regulators, battery charger, RTC, ADC, backlight
    dri= ver and current sinks. This patch enables LP8788 backlight module.

    (Brightness mode)
    The brightness is controlled by PWM input or I2C register.
    All modes are supported in the driver.

    (Platform data)
    Configurable data can be defined in the platform side.
    name : backlight driver name. (default: "lcd-backlight")
    initial_brightness : initial value of backlight brightness
    bl_mode : brightness control by PWM or lp8788 register
    dim_mode : dimming mode selection
    full_scale : full scale current setting
    rise_time : brightness ramp up step time
    fall_time : brightness ramp down step time
    pwm_pol : PWM polarity setting when bl_mode is PWM based
    period_ns : platform specific PWM period value. unit is nano.

    The default values are set in case no platform data is defined.

  • 08d816b8c   lp8788-charger: Fix ADC channel names ... Browse Code »

    The name of ADC channel is configurable in the platform side. This name is
    referenced in the IIO consumer driver. To get the IIO channel, specific
    name in the platform data is used as an parameter of the
    iio_channel_get(). Thus, lp8788_adc_id platform data are replaced with
    specific names.

  • eea6b7cc5   mfd: Add lp8788 mfd driver ... Browse Code »

    TI LP8788 PMU provides regulators, battery charger, ADC,
    RTC, backlight driver and current sinks.

    This MFD patch supports the I2C communication using the regmap,
    the interrupt handling using the linear IRQ domain and
    configurable platform data structures for each driver module.

    (Driver Architecture)

    < mfd devices >
    LP8788 HW .......... mfd .......... regulator drivers
    I2C power supply driver
    IRQs iio adc driver
    rtc driver
    backlight driver
    current sink drivers

    o regulators : LDOs and BUCKs
    o power supply : Battery charger
    o iio adc : Battery voltage/temperature
    o rtc : RTC and alarm
    o backlight
    o current sink : LED and vibrator

    All MFD device modules are registered by LP8788 MFD core driver.
    For sharing information such like the virtual IRQ number,
    MFD core driver uses the resource structure.
    Then each module can retrieve the specific IRQ number and detect it
    in the IRQ thread.

    Configurable platform data is handled in each driver module.
