  • 82d8eb40b   mfd: max77620: Fix FPS switch statements ... Browse Code »

    When configuring FPS during probe, assuming a DT node is present for
    FPS, the code can run into a problem with the switch statements in
    max77620_config_fps() and max77620_get_fps_period_reg_value(). Namely,
    in the case of chip->chip_id == MAX77620, it will set
    fps_[mix|max]_period but then fall through to the default switch case
    and return -EINVAL. Returning this from max77620_config_fps() will
    cause probe to fail.

  • 3df140d11   mfd: max77620: Mask/unmask interrupt before/after servicing it ... Browse Code »

    The programming guidelines of the MAX77620 for servicing interrupt is:
    1. When interrupt occurs from PMIC, mask the PMIC interrupt by
    setting GLBLM.
    2. Read IRQTOP and service the interrupt.
    3. Once all interrupts has been checked and serviced, the interrupt
    service routine un-masks the hardware interrupt line by clearing
    GLBLM.

    Add the pre and post interrupt service handler for mask and unmask the
    global interrupt mask bit (for step 1 and 3) as callback from regmap-irq.

  • c1fe7c452   mfd: max77620: Make it explicitly non-modular ... Browse Code »

    The Kconfig currently controlling compilation of this code is:

    drivers/mfd/Kconfig:config MFD_MAX77620
    drivers/mfd/Kconfig: bool "Maxim Semiconductor MAX77620 and MAX20024 PMIC Support"

    ...meaning that it currently is not being built as a module by anyone.

    Lets remove the modular code that is essentially orphaned, so that
    when reading the driver there is no doubt it is builtin-only.

    Since module_i2c_driver() uses the same init level priority as
    builtin_i2c_driver() the init ordering remains unchanged with
    this commit.

    Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

    We also delete the MODULE_LICENSE tag etc. since all that information
    was (or is now) contained at the top of the file in the comments.

    MAX77620/MAX20024 are Power Management IC from the MAXIM.
    It supports RTC, multiple GPIOs, multiple DCDC and LDOs,
    watchdog, clock etc.

    Add MFD drier to provides common support for accessing the
    device; additional drivers is developed on respected subsystem
    in order to use the functionality of the device.
