6f4642e0e2 clk: Provide new devm_clk helpers for prepared and enabled clocks
[ Upstream commit 7ef9651e9792b08eb310c6beb202cbc947f43cab ]

When a driver keeps a clock prepared (or enabled) during the whole
lifetime of the driver, these helpers allow to simplify the drivers.

f8f353585d clk: Add (devm_)clk_get_optional() functions
[ Upstream commit 60b8f0ddf1a927ef02141a6610fd52575134f821 ]

This adds clk_get_optional() and devm_clk_get_optional() functions to get
optional clocks.

They behave the same as (devm_)clk_get() except where there is no clock
producer. In this case, instead of returning -ENOENT, the function
returns NULL. This makes error checking simpler and allows
clk_prepare_enable, etc to be called on the returned reference
without additional checks.

92e79e1c0f clk: Fix undefined reference to `clk_rate_exclusive_{get,put}'
[ Upstream commit 2746f13f6f1df7999001d6595b16f789ecc28ad1 ]

The COMMON_CLK config is not enabled in some of the architectures.
This causes below build issues:

pwm-rz-mtu3.c:(.text+0x114):
undefined reference to `clk_rate_exclusive_put'
pwm-rz-mtu3.c:(.text+0x32c):
undefined reference to `clk_rate_exclusive_get'

Fix these issues by moving clk_rate_exclusive_{get,put} inside COMMON_CLK
code block, as clk.c is enabled by COMMON_CLK.

9fba738a53 clk: add duty cycle support
Add the possibility to apply and query the clock signal duty cycle ratio.

This is useful when the duty cycle of the clock signal depends on some
other parameters controlled by the clock framework.

For example, the duty cycle of a divider may depends on the raw divider
setting (ratio = N / div) , which is controlled by the CCF. In such case,
going through the pwm framework to control the duty cycle ratio of this
clock would be a burden.

A clock provider is not required to implement the operation to set and get
the duty cycle. If it does not implement .get_duty_cycle(), the ratio is
assumed to be 50%.

This change also adds a new flag, CLK_DUTY_CYCLE_PARENT. This flag should
be used to indicate that a clock, such as gates and muxes, may inherit
the duty cycle ratio of its parent clock. If a clock does not provide a
get_duty_cycle() callback and has CLK_DUTY_CYCLE_PARENT, then the call
will be directly forwarded to its parent clock, if any. For
set_duty_cycle(), the clock should also have CLK_SET_RATE_PARENT for the
call to be forwarded

55e9b8b7b8 clk: add clk_rate_exclusive api
Using clock rate protection, we can now provide a way for clock consumer
to claim exclusive control over the rate of a producer

So far, rate change operations have been a "last write wins" affair. This
changes allows drivers to explicitly protect against this behavior, if
required.

Of course, if exclusivity over a producer is claimed more than once, the
rate is effectively locked as exclusivity cannot be preempted

71a2f11511 clk: add devm_get_clk_from_child() API
Some driver is using this type of DT bindings for clock (more detail,
see ${LINUX}/Documentation/devicetree/bindings/sound/simple-card.txt).

	sound_soc {
		...
		cpu {
			clocks = <&xxx>;
			...
		};
		codec {
			clocks = <&xxx>;
			...
		};
	};

Current driver in this case uses of_clk_get() for each node, but there
is no devm_of_clk_get() today.
OTOH, the problem of having devm_of_clk_get() is that it encourages the
use of of_clk_get() when clk_get() is more desirable.

Thus, this patch adds new devm_get_clk_from_chile() which explicitly
reads as get a clock from a child node of this device.
By this function, we can also use this type of DT bindings

	sound_soc {
		clocks = <&xxx>, <&xxx>;
		clock-names = "cpu", "codec";
		clock-ranges;
		...
		cpu {
			...
		};
		codec {
			...
		};
	};

if the two pointers reference the same clock hardware. This behavior is
dubious (drivers must not dereference struct clk), but did not cause any

for matching clk's will always fail with per-user struct clk's.

clk_is_match is introduced to fix the regression and prevent drivers
from comparing the pointers manually.

Pull clock tree updates from Mike Turquette:
 "The clk tree changes for 3.18 are dominated by clock drivers.  Mostly
  fixes and enhancements to existing drivers as well as new drivers.
  This tag contains a bit more arch code than I usually take due to some
  OMAP2+ changes.  Additionally it contains the restart notifier
  handlers which are merged as a dependency into several trees.

  The PXA changes are the only messy part.  Due to having a stable tree
  I had to revert one patch and follow up with one more fix near the tip
  of this tag.  Some dead code is introduced but it will soon become
  live code after 3.18-rc1 is released as the rest of the PXA family is
  converted over to the common clock framework.

  Another trend in this tag is that multiple vendors have started to
  push the complexity of changing their CPU frequency into the clock
  driver, whereas this used to be done in CPUfreq drivers.

  Changes to the clk core include a generic gpio-clock type and a
  clk_set_phase() function added to the top-level clk.h api.  Due to
  some confusion on the fbdev mailing list the kernel boot parameters
  documentation was updated to further explain the clk_ignore_unused
  parameter, which is often required by users of the simplefb driver.

  Finally some fixes to the locking around the clock debugfs stuff was
  done to prevent deadlocks when interacting with other subsystems."

5279fc402a clk: add clk accuracy retrieval support
The clock accuracy is expressed in ppb (parts per billion) and represents
the possible clock drift.
Say you have a clock (e.g. an oscillator) which provides a fixed clock of
20MHz with an accuracy of +- 20Hz. This accuracy expressed in ppb is
20Hz/20MHz = 1000 ppb (or 1 ppm).

Clock users may need the clock accuracy information in order to choose
the best clock (the one with the best accuracy) across several available
clocks.

This patch adds clk accuracy retrieval support for common clk framework by
means of a new function called clk_get_accuracy.
This function returns the given clock accuracy expressed in ppb.

In order to get the clock accuracy, this implementation adds one callback
called recalc_accuracy to the clk_ops structure.
This callback is given the parent clock accuracy (if the clock is not a
root clock) and should recalculate the given clock accuracy.

This callback is optional and may be implemented if the clock is not
a perfect clock (accuracy != 0 ppb).

fb72a0590b clk: Properly handle notifier return values
Notifiers may return NOTIFY_(OK|DONE|STOP|BAD). The CCF uses an
inconsistent mix of checking against NOTIFY_STOP or NOTIFY_BAD.
This inconsistency leaves errors undetected in some cases:
clk_set_parent() calls __clk_speculate_rates(), which stops when it
hits a NOTIFIER_BAD (STOP is ignored), and passes this value back to the
caller.
clk_set_parent() compares this return value against NOTIFY_STOP only,
ignoring NOTIFY_BAD returns.

Use NOTIFY_STOP_MASK to detect a negative notifier return value and
document all four return value options.

93abe8e4b1 clk: add non CONFIG_HAVE_CLK routines
Many drivers are shared between architectures that may or may not have
HAVE_CLK selected for them.  To remove compilation errors for them we
enclose clk_*() calls in these drivers within #ifdef CONFIG_HAVE_CLK,
#endif.

This patch removes the need of these CONFIG_HAVE_CLK statements, by
introducing dummy routines when HAVE_CLK is not selected by platforms.
So, definition of these routines will always be available.  These calls
will return error for platforms that don't select HAVE_CLK.

9f1612d351 clk: fix clk_get on of_clk_get_by_name return check
The commit 766e6a4 (clk: add DT clock binding support) plugs device
tree clk lookup of_clk_get_by_name into clk_get, and fall on non-DT
lookup clk_get_sys if DT lookup fails.

The return check on of_clk_get_by_name takes (clk != NULL) as a
successful DT lookup.  But it's not the case.  For any system that
does not define clk lookup in device tree, ERR_PTR(-ENOENT) will be
returned, and consequently, all the client drivers calling clk_get
in their probe functions will fail to probe with error code -ENOENT
returned.

Fix the issue by checking of_clk_get_by_name return with !IS_ERR(clk),
and update of_clk_get and of_clk_get_by_name for !CONFIG_OF build
correspondingly.

766e6a4ec6 clk: add DT clock binding support
Based on work 1st by Ben Herrenschmidt and Jeremy Kerr, then by Grant
Likely, this patch adds support to clk_get to allow drivers to retrieve
clock data from the device tree.

Platforms scan for clocks in DT with of_clk_init and a match table, and
the register a provider through of_clk_add_provider. The provider's
clk_src_get function will be called when a device references the
provider's OF node for a clock reference.

v6 (Rob Herring):
    - Return error values instead of NULL to match clock framework
      expectations

v5 (Rob Herring):
    - Move from drivers/of into common clock subsystem
    - Squashed "dt/clock: add a simple provider get function" and
      "dt/clock: add function to get parent clock name"
    - Rebase to 3.4-rc1
    - Drop CONFIG_OF_CLOCK and just use CONFIG_OF
    - Add missing EXPORT_SYMBOL to various functions
    - s/clock-output-name/clock-output-names/
    - Define that fixed-clock binding is a single output

v4 (Rob Herring):
    - Rework for common clk subsystem
    - Add of_clk_get_parent_name function

v3: - Clarified documentation

v2: - fixed errant ';' causing compile error
    - Editorial fixes from Shawn Guo
    - merged in adding lookup to clkdev
    - changed property names to match established convention. After
      working with the binding a bit it really made more sense to follow the
      lead of 'reg', 'gpios' and 'interrupts' by making the input simply
      'clocks' & 'clock-names' instead of 'clock-input-*', and to only use
      clock-output* for the producer nodes. (Sorry Shawn, this will mean
      you need to change some code, but it should be trivial)
    - Add ability to inherit clocks from parent nodes by using an empty
      'clock-ranges' property.  Useful for busses.  I could use some feedback
      on the new property name, 'clock-ranges' doesn't feel right to me.

b2476490ef clk: introduce the common clock framework
The common clock framework defines a common struct clk useful across
most platforms as well as an implementation of the clk api that drivers
can use safely for managing clocks.

The net result is consolidation of many different struct clk definitions
and platform-specific clock framework implementations.

This patch introduces the common struct clk, struct clk_ops and an
implementation of the well-known clock api in include/clk/clk.h.
Platforms may define their own hardware-specific clock structure and
their own clock operation callbacks, so long as it wraps an instance of
struct clk_hw.

See Documentation/clk.txt for more details.

This patch is based on the work of Jeremy Kerr, which in turn was based
on the work of Ben Herrenschmidt.

40d3e0f494 clk: provide prepare/unprepare functions
As discussed previously, there's the need on some platforms to run some
parts of clk_enable() in contexts which can schedule.  The solution
which was agreed upon was to provide clk_prepare() and clk_unprepare()
to contain this parts, while clk_enable() and clk_disable() perform
the atomic part.

This patch provides a common definition for clk_prepare() and
clk_unprepare() in linux/clk.h, and provides an upgrade path for
existing implementation and drivers: drivers can start using
clk_prepare() and clk_unprepare() once this patch is merged without
having to wait for platform support.  Platforms can then start to
provide these additional functions.

Eventually, HAVE_CLK_PREPARE will be removed from the kernel, and
everyone will have to provide these new APIs.
