  • 842078054   gpio/pca953x bugfix: mark as can_sleep ... Browse Code »

    The pca953x driver is an I2C driver so gpio_chip->can_sleep should be set.
    This lets upper layers know they should use the gpio_*_cansleep() calls to
    access values, and may not access them from nonsleeping contexts.

  • f5e8ff483   gpio: handle pca953{4,5,6,7,8} too ... Browse Code »

    This third part of an extension to support more pca953x chips updates the
    logic to handle the smaller register widths used by the 4-bit and 8-bit parts,
    and to use the chip type to determine how many GPIOs it provides.

    As long as we don't support interrupt and reset capabilities, those size
    issues are the only software-visible differences between these parts.

  • 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.

  • d1c057e31   gpio: rename pca9539 driver ... Browse Code »

    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.
