  • 439a36d7d   clk: sunxi: make clk-* explicitly non-modular ... Browse Code »

    We have the following file --> Kconfig mapping:

    sunxi/clk-factors.c obj-y
    sunxi/clk-sun6i-apb0-gates.c CONFIG_MFD_SUN6I_PRCM (bool)
    sunxi/clk-sun6i-apb0.c CONFIG_MFD_SUN6I_PRCM
    sunxi/clk-sun6i-ar100.c CONFIG_MFD_SUN6I_PRCM
    sunxi/clk-sun8i-apb0.c CONFIG_MFD_SUN6I_PRCM
    sunxi/clk-sun9i-mmc.c obj-y

    Hence none of these are being built as a module by anyone.

    Lets remove the modular code that is essentially orphaned, so that
    when reading the drivers there is no doubt they are builtin-only. All
    drivers get mostly the same changes, so they are handled in batch.

    Changes are (1) convert to builtin_platform_register, (2) use the
    init.h header, (3) delete the MODULE_LICENCE/MODULE_AUTHOR and
    associated tags, and (4) delete any ".remove" functions.

    There was a stray module.h in a file not using any init.h or
    module.h stuff, so we simply removed that one.

    In two cases, we explicitly disallow a driver unbind, since that
    doesn't have a sensible use case anyway, and it allows us to drop
    the ".remove" code for non-modular drivers.

    Since module_platform_driver() uses the same init level priority as
    builtin_platform_driver() the init ordering remains unchanged with
    this commit.

    We delete the MODULE_LICENSE etc. tags since all that information
    is already contained at the top of each file in the comments.

  • 59c0621d4   clk: Remove .owner field for driver ... Browse Code »

    There is no need to init .owner field.

    Based on the patch from Peter Griffin
    "mmc: remove .owner field for drivers using module_platform_driver"

    This patch removes the superflous .owner field for drivers which
    use the module_platform_driver API, as this is overriden in
    platform_driver_register anyway."

  • cd6eb534f   clk: sunxi: Fix gate indexing for sun6i-a31-apb0-gates ... Browse Code »

    sun6i-a31-apb0-gates supports using clock-indices for holes between
    individual gates. However, the driver passes the number of gates
    registered in clk_data->clk_num, which of_clk_src_onecell_get uses
    to recognize the range of valid indices a consumer can use.

    This patch makes the driver pass the maximum gate index + 1, so
    of_clk_src_onecell_get does not complain about indices greater
    than gates registered.

    This was tested on the A23 SoC, which has a similar APB0 clock,
    but has holes for gates to removed IP blocks.

  • c3dcac875   clk: sunxi: fix devm_ioremap_resource error detection code ... Browse Code »

    devm_ioremap_resource returns an ERR_PTR value, not NULL, on failure.

    A simplified version of the semantic match that finds this problem is as
    follows:

    //
    @@
    expression e,e1;
    statement S;
    @@

    *e = devm_ioremap_resource(...);
    if (!e1) S

  • c8a76cac1   clk: sunxi: add PRCM (Power/Reset/Clock Management) clks support ... Browse Code »

    The PRCM (Power/Reset/Clock Management) unit provides several clock
    devices:
    - AR100 clk: used to clock the Power Management co-processor
    - AHB0 clk: used to clock the AHB0 bus
    - APB0 clk and gates: used to clk peripherals connected to the APB0 bus

    Add support for these clks in a separate driver so that they can be probed
    as platform devices instead of registered during early init.
    This is needed to be able to probe PRCM MFD subdevices.
