clk: sunxi: Fix M factor computation for APB1

2016-11-04T07:49:46+00:00

commit cfa636886033 ("clk: sunxi: factors: Consolidate get_factors
parameters into a struct") introduced a regression for m factor
computation in sun4i_get_apb1_factors function.

The old code reassigned the "parent_rate" parameter to the targeted
divisor value and was buggy for the returned frequency but not for the
computed factors. Now, returned frequency is good but m factor is
incorrectly computed (its max value 31 is always set resulting in a
significantly slower frequency than the requested one...)

This patch simply restores the original proper computation for m while
keeping the good changes for returned rate.

2016-09-08T19:57:10+00:00

* clk-fixes:
  clk: sunxi-ng: Fix wrong reset register offsets
  clk: sunxi-ng: nk: Make ccu_nk_find_best static
  clk: sunxi-ng: Fix inverted test condition in ccu_helper_wait_for_lock

clk: sunxi: apb0: Use new macro CLK_OF_DECLARE_DRIVER

2016-08-13T01:01:50+00:00

This driver initializes a clock provider via sun8i_a23_apb0_setup
and then continues the initialization on sun8i_a23_apb0_clk_probe.

Use the new macro to notify the clk subsystem about this behaviour.

clk: sunxi: Fix return value check in sun8i_a23_mbus_setup()

2016-08-08T17:27:33+00:00

In case of error, the function of_io_request_and_map() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR().

clk: sunxi: make clk-* explicitly non-modular

2016-07-06T22:20:34+00:00

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.
