  • b1224cd11   mfd: Avoid two assignments if failures happen in tps65910_i2c_probe ... Browse Code »

    In drivers/mfd/tps65910.c:tps65910_i2c_probe() there's potential for a
    tiny optimization.

    We assign to init_data->irq and init_data->irq_base long before we
    need them, and there are two potential exits from the function before
    they are needed.

    Moving the assignments below these two potential exits means we
    completely avoid doing them in these two (failure) cases.

    There are a couple of situations where we leak init_data in
    drivers/mfd/tps65910.c:tps65910_i2c_probe() - this patch should take
    care of them.

  • ec2328c30   mfd: Implement tps65910 IRQ cleanup ... Browse Code »

    The tps65910_irq_exit() cleanup function was generating a warning from
    sparse due to the lack of a prototype. This wasn't causing GCC warnings
    as the driver wasn't cleaning up its IRQs on exit at all so there was no
    use of an unprototyped function.

  • 795570561   MFD: TPS65910: Add support for TPS65911 device ... Browse Code »

    The TPS65911 is the next generation of the TPS65910 family of
    PMIC chips. It adds a few features:

    - Watchdog Timer
    - PWM & LED generators
    - Comparators for system control status

    It also adds a set of Interrupts and GPIOs, among other things.

    The driver exports a function to identify between different
    versions of the tps65910 family, allowing other modules to
    identify the capabilities of the current chip.

    If bytes == (TPS65910_MAX_REGISTER + 1), we have a buffer overflow when
    doing memcpy(&msg[1], src, bytes).

  • e3471bdc2   TPS65910: IRQ: Add interrupt controller ... Browse Code »

    This module controls the interrupt handling for the tps chip. The
    interrupt sources are the following:

    - GPIO falling/rising edge detection
    - Battery voltage below/above threshold
    - PWRON signal
    - PWRHOLD signal
    - Temperature detection
    - RTC alarm and periodic event

    TPS65910 has one configurable GPIO that can be used for several
    purposes. Subsequent versions of the TPS chip support more than
    one GPIO.

    The TPS65910 chip is a power management IC for multimedia and handheld
    devices. It contains the following components:

    - Regulators
    - GPIO controller
    - RTC

    The tps65910 core driver is registered as a platform driver and provides
    communication through I2C with the host device for the different
    components.
