    this macro is an extension of readx_poll_timeout macro. the accessor
    function op just supports only one parameter in the readx_poll_timeout
    macro, but this macro can supports multiple variable parameters for
    it. so functions like phy_read(struct phy_device *phydev, u32 regnum)
    and phy_read_mmd(struct phy_device *phydev, int devad, u32 regnum) can
    also use this poll timeout core. and also expand it can sleep some time
    before read operation.

  • 458f69ef3   docs: timers: convert docs to ReST and rename to *.rst ... Browse Code »

    The conversion here is really trivial: just a bunch of title
    markups and very few puntual changes is enough to make it to
    be parsed by Sphinx and generate a nice html.

    The conversion is actually:
    - add blank lines and identation in order to identify paragraphs;
    - fix tables markups;
    - add some lists markups;
    - mark literal blocks;
    - adjust title markups.

    At its new index.rst, let's add a :orphan: while this is not linked to
    the main index.rst file, in order to avoid build warnings.

  • d15809f36   iopoll: avoid -Wint-in-bool-context warning ... Browse Code »

    When we pass the result of a multiplication as the timeout or the delay,
    we can get a warning from gcc-7:

    drivers/mmc/host/bcm2835.c:596:149: error: '*' in boolean context, suggest '&&' instead [-Werror=int-in-bool-context]
    drivers/mfd/arizona-core.c:247:195: error: '*' in boolean context, suggest '&&' instead [-Werror=int-in-bool-context]
    drivers/gpu/drm/sun4i/sun4i_hdmi_i2c.c:49:27: error: '*' in boolean context, suggest '&&' instead [-Werror=int-in-bool-context]

    The warning is a bit questionable inside of a macro, but this is
    intentional on the side of the gcc developers. It is also an indication
    of another problem: we evaluate the timeout and sleep arguments multiple
    times, which can have undesired side-effects when those are complex
    expressions.

    This changes the two iopoll variants to use local variables for storing
    copies of the timeouts. This adds some more type safety, and avoids
    both the double-evaluation and the gcc warning.

  • 54c523127   iopoll: Introduce memory-mapped IO polling macros ... Browse Code »

    It is sometimes necessary to poll a memory-mapped register until its value
    satisfies some condition. Introduce a family of convenience macros that do
    this. Tight-looping, sleeping, and timing out can all be accomplished using
    these macros.
