  • 7637c9259   drivers/staging/olpc_dcon: convert to new cs5535 gpio API ... Browse Code »

    Drop the old geode_gpio crud, as well as the raw outl() calls; instead,
    use the Linux GPIO API where possible, and the cs5535_gpio API in other
    places.

    Note that we don't actually clean up the driver properly yet (once loaded,
    it always remains loaded). That'll come later..

    This patch is necessary for building the driver.

  • 1b912c1bc   drivers/gpio/cs5535-gpio.c: add some additional cs5535-specific GPIO functionality ... Browse Code »

    This adds (well, re-adds actually) handling for events/IRQs through cs5535
    GPIOs. In the wild and wooly world of CS5535, setup_event() is for
    assigning an IRQ to a GPIO filter/event pair, and set_irq() sets up the
    pair to trigger IRQs.

    These should really only be used in highly platform-specific drivers (such
    as OLPC's DCON driver). Sadly, because set_irq() uses MSRs, this causes
    the driver to become X86-specific.

    ..and include them in the lxfb/gxfb drivers rather than asm/geode.h (where
    possible).

    The only thing that uses this is the reboot_fixups code.

  • 82dca611b   cs5535: add a generic MFGPT driver ... Browse Code »

    This is based on the old code on arch/x86/kernel/mfgpt_32.c, except it's
    not x86 specific, it's modular, and it makes use of a PCI BAR rather than
    a random MSR. Currently module unloading is not supported; it's uncertain
    whether or not it can be made work with the hardware.

  • 5f0a96b04   cs5535-gpio: add AMD CS5535/CS5536 GPIO driver support ... Browse Code »

    This creates a CS5535/CS5536 GPIO driver which uses a gpio_chip backend
    (allowing GPIO users to use the generic GPIO API if desired) while also
    allowing architecture-specific users directly (via the cs5535_gpio_*
    functions).

    Tested on an OLPC machine. Some Leemotes also use CS5536 (with a mips
    cpu), which is why this is in drivers/gpio rather than arch/x86.
    Currently, it conflicts with older geode GPIO support; once MFGPT support
    is reworked to also be more generic, the older geode code will be removed.
