  • LP3943 has 16 output pins which can be used as GPIO expander and PWM generator.

    * Regmap I2C interface for R/W LP3943 registers

    * Atomic operations for output pin assignment
    The driver should check whether requested pin is available or not.
    If the pin is already used, pin request returns as a failure.
    A driver data, 'pin_used' is checked when gpio_request() and
    pwm_request() are called. If the pin is available, then pin_used is set.
    And it is cleared when gpio_free() and pwm_free().

    * Device tree support
    Compatible strings for GPIO and PWM driver.
    LP3943 platform data is PWM related, so parsing the device tree is
    implemented in the PWM driver.
