  • d87574332   clk:mxs: Fix bug on frequency divider ... Browse Code »

    On drivers/clk/mxs/clk-frac.c, the function clk_frac_round_rate returned a bad
    result. The division before multiplication computes a wrong value ; the
    calculation is inverted to fix the problem. The second issue is that the exact
    rate have decimals and they are truncate. The consequence is that the function
    clk_frac_set_rate (which use the result of clk_frac_round_rate) computes a
    wrong value for the register (the rate generated can be closer to the desired
    rate). The correction is : if there is decimal to the result, it is rounded to
    the next larger integer.
    On drivers/clk/mxs/clk-frac.c, the function clk_frac_recalc_rate returned
    a bad result. The multiplication is made before the division to compute a
    correct value.

  • bb0bf3545   clk: mxs: Include clk.h in C files that use it ... Browse Code »

    Clock provider drivers generally shouldn't include clk.h because
    it's the consumer API. The clk.h include is being included in all
    mxs files because it's part of mxs/clk.h even though nothing
    actually requires it in that file. Move the clk.h include to the
    C files that are actually using it and remove the clk.h include
    from the header file. The clkdev.h include isn't used either, so
    drop it too.

  • 692d8328e   clk: don't use __initconst for non-const arrays ... Browse Code »

    The statement

    static const char *name[];

    defines a modifiable array of pointers to constant chars. That is

    *name[0] = 'f';

    is forbidden, but

    name[0] = "f";

    is not. So marking an array that is defined as above with __initconst is
    wrong. Either an additional const must be added such that the whole
    definition reads:

    static const char *const name[] __initconst;

    or where this is not possible __initdata must be used.

    Add a CLK_SET_RATE_NO_REPARENT clock flag, which will prevent muxes
    being reparented during clk_set_rate.

    To avoid breaking existing platforms, all callers of clk_register_mux()
    are adjusted to pass the new flag. Platform maintainers are encouraged
    to remove the flag if they wish to allow mux reparenting on set_rate.

  • 2fb318ff7   ARM: mxs: use apbx bus clock to drive the timers on timrotv2 ... Browse Code »

    timer resolution of ~32us is pretty low.
    v2 has 32bits resolution, so we have quite some headroom, and
    can use the 24MHz clock.
    v1 has only 16bits, so we only increase v2.

    So we just exchange the timrot clock in imx28.
    On imx23 we have timrotv1 and everything stays the same.

    It really becomes a maintenance issue that every time a device needs

    clk_register_clkdev for that clock.

    Since clock DT support which is meant to resolve clock lookup in device
    tree is in place, the patch moves imx23 client devices' clock lookup
    over to device tree, so that any new lookup to be added at later time
    can just get done in DT instead of kernel.
