  • 3c1ab50d0   drivers/leds/leds-pca9532.c: add gpio capability ... Browse Code »

    Allow unused leds on pca9532 to be used as gpio. The board I am working
    on now has no less than 6 pca9532 chips. One chips is used for only leds,
    one has 14 leds and 2 gpio and the rest of the chips are gpio only.

    There is also one board in mainline which could use this capabilty;
    arch/arm/mach-iop32x/n2100.c
    232 { .type = PCA9532_TYPE_NONE }, /* power OFF gpio */
    233 { .type = PCA9532_TYPE_NONE }, /* reset gpio */

    This patch defines a new pin type, PCA9532_TYPE_GPIO, and registers a
    gpiochip if any pin has this type set. The gpio will registers all chip
    pins but will filter on gpio_request.

  • e14fa8243   leds: Add pca9532 led driver ... Browse Code »

    NXP pca9532 is a LED dimmer/controller attached to i2c bus. It allows
    attaching upto 16 leds which can either be on, off or dimmed and/or blinked
    with the two PWM modulators available.

    This driver is a "new-style" i2c driver that adheres to the driver model and
    implements the led framework api. Since the leds connected to the driver are
    platform specific, it is only useful when platform data is passed to the
    driver to define what leds are connected to which pins.
