Merge tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux

Pull module_platform_driver replacement from Paul Gortmaker:
 "Replace module_platform_driver with builtin_platform driver in non
  modules.

  We see an increasing number of non-modular drivers using
  modular_driver() type register functions.  There are several downsides
  to letting this continue unchecked:

   - The code can appear modular to a reader of the code, and they won't
     know if the code really is modular without checking the Makefile
     and Kconfig to see if compilation is governed by a bool or
     tristate.

   - Coders of drivers may be tempted to code up an __exit function that
     is never used, just in order to satisfy the required three args of
     the modular registration function.

   - Non-modular code ends up including the  which increases
     CPP overhead that they don't need.

   - It hinders us from performing better separation of the module init
     code and the generic init code.

  So here we introduce similar macros for builtin drivers.  Then we
  convert builtin drivers (controlled by a bool Kconfig) by making the
  following type of mapping:

    module_platform_driver()       --->  builtin_platform_driver()
    module_platform_driver_probe() --->  builtin_platform_driver_probe().

  The set of drivers that are converted here are just the ones that
  showed up as relying on an implicit include of  during a
  pending header cleanup.  So we convert them here vs adding an include
  of  to non-modular code to avoid compile fails.  Additonal
  conversions can be done asynchronously at any time.

  Once again, an unused module_exit function that is removed here
  appears in the diffstat as an outlier wrt all the other changes"

drivers/clk: convert sunxi/clk-mod0.c to use builtin_platform_driver

2015-06-16T18:12:39+00:00

This driver builds based on obj-y and hence will not ever be
modular.  Change it to use the non-modular registration so that it
won't suffer a compile fail once a header move places the modular
registration within the module.h file.

clk: sunxi: Add support for the usb-clk on sun8i a23 and a33 SoCs

2015-06-02T08:24:39+00:00

The usb-clk on sun8i a23 and a33 SoCs is similar to the ones found
on sun6i-a31 SoCs but instead of a 3th phy the a23 / a33 have a hsic
interface which gets enabled by almost the same bits as used on
the a31 for the 3rd phy, but not exactly the same bits so we need
a new compatible for this.

clk: sunxi: Fix of_io_request_and_map error check

2015-05-05T15:43:57+00:00

of_io_request_and map returns an error pointer, but the current code assumes
that on error the returned pointer will be NULL.

Obviously, that makes the check completely useless. Change the test to actually
check for the proper error code.

clk: sunxi: Add pll6 / 4 clock output to sun4i-a10-pll6

2015-03-25T18:46:41+00:00

The pll6 has a /4 output that is used as an input to the ahb mux clock.

clk: sunxi: Make divs clocks specify which output is the base factor clock

2015-03-25T18:46:32+00:00

The current sunxi clock driver has the base factor clock of divs clocks
as the last clock output of the clock node. This makes it rather difficult
to add new outputs, such as fixed dividers, which were previously unknown.

This patch makes the divs clocks data structure specify which output is
the factor clock, and updates all current divs clocks accordingly.

We can then add new outputs after the factor clocks, at least not breaking
backward compatibility with regards to the devicetree bindings.

Also replace kzalloc with kcalloc in sunxi_divs_clk_setup().

clk: sunxi: Register divs clocks before factor clocks

2015-03-21T10:49:57+00:00

We want to reparent AHB clock to PLL6 on sun5i/sun7i using the assigned
clocks properties. AHB is a factor clock, while PLL6 is a divs clock.

Register divs clocks before factor clocks so reparenting works. This
is only needed because we do the reparenting on the clock provider.

The proper way to fix this is to split out all the old sunxi clocks
into separate CLK_OF_DECLARE statements, like we are doing for sun9i.

clk: sunxi: Add "cpu" to list of protected clocks for sun5i

2015-03-21T10:49:21+00:00

Now that the ahb clock on sun5i/sun7i is muxable, ahb is no longer
guaranteed to be a child of the cpu clock. Add the cpu clock to
the list of protected clocks so it doesn't get disabled.
