  • 6a7b36aa4   GPIO: PCA953X: Increase size of invert variable to support 24 bit ... Browse Code »

    TCA6424 is a low voltage 24 bit I2C and SMBus I/O expander of pca953x family
    similar to its 16 bit predecessor TCA6416. It comes with three 8-bit active
    Input, Output, Polarity Inversion and Configuration registers each. The polarity
    of Input ports can be reversed by setting the appropiate bit in Polarity
    Inversion registers.

    The variables corresponding to Input, Output and Configuration registers have
    already been updated to support 24 bit values. This patch thus updates the
    invert variable of PCA953X platform data to support 24 bit.

    gpiolib doesn't need to modify the names and I assume most initializers
    use string constants that shouldn't be modified anyhow.

  • 89ea8bbe9   gpio: pca953x.c: add interrupt handling capability ... Browse Code »

    Most of the GPIO expanders controlled by the pca953x driver are able to
    report changes on the input pins through an *INT pin.

    This patch implements the irq_chip functionality (edge detection only).

    The driver has been tested on an Arcom Zeus.

    linux/i2c/pca953x.h is a very bare include file. Fix check for multiple
    includes of linux/i2c/pca953x.h, and add dependent includes into the
    header file.

  • f3dc3630f   gpio: rename pca953x symbols ... Browse Code »

    This second part of an extension to support more pca953x chips renames the C
    and Kconfig symbols. All affected files were updated by sed, except for a
    couple of obvious exceptions. It also updates the Kconfig helptext.

    First part of an extension to let the pca9539 driver support more chips,
    starting with pca9534, pca9535, pca9536, pca9537, and pca9538.

    This renames the files and modifies the Makefile.
