This V2 patch changes the clock disabling behavior during boot.
Two different changes are made:1) Delay disabling of clocks until late in the boot process.
This fixes an existing issue where in-use clocks without
software reference are disabled by mistake during boot.
One example of this is the handling of the Mackerel serial
console output that shares clock with the I2C controller.2) Write out the "disabled" state to the hardware for clocks
that not have been used by the kernel. In other words,
make sure so far unused clocks actually get turned off.Signed-off-by: Magnus Damm

Convert the SuperH clocks framework and shared interrupt handling
code to using struct syscore_ops instead of a sysdev classes and
sysdevs for power managment.This reduces the code size significantly and simplifies it. The
optimizations causing things not to be restored after creating a
hibernation image are removed, but they might lead to undesirable
effects during resume from hibernation (e.g. the clocks would be left
as the boot kernel set them, which might be not the same way as the
hibernated kernel had seen them before the hibernation).This also is necessary for removing sysdevs from the kernel entirely
in the future.Signed-off-by: Rafael J. Wysocki

Presently the root node is initialized by way of kzalloc on the parent
data structure, which by chance happens to do the bulk of what an
explicit initialization does with GFP_NOWAIT semantics. This however is
more by luck than by design, and as we ideally want to permit radix node
allocations access to the emergency pools anyways, add in the proper
initializer with the desired mask.Signed-off-by: Paul Mundt

Sometimes it is possible and reasonable to adjust the parent clock rate to
improve precision of the child clock, e.g., if the child clock has no siblings.
clk_round_parent() is a new addition to the SH clock-framework API, that
implements such an optimization for child clocks with divisors, taking all
integer values in a range.Signed-off-by: Guennadi Liakhovetski

to follow the intc split up. This will make it easier to subsequently

The end condition of for_each_frequency should care about
both clk_rate_table_round and clk_rate_div_range_round,
and using "correct max size" is a natural idea in later function.
To avoid data over flow, this patch didn't modify
clk_rate_div_range_round side as .max = div_max + 1.Signed-off-by: Kuninori Morimoto

This adds a new clk_rate_div_range_round() for implementing rate rounding
by divisor ranges. This can be used trivially by clocks that support
arbitrary ranged divisors without the need for rate table construction.This should only be used by clocks that both have large divisor ranges in
addition to clocks that will never be arbitrarily scaled, as the lack of
a backing frequency table will prevent cpufreq from being able to do much
of anything with them.Primarily intended for use as a ->recalc helper.

Presently the only assisted rate rounding is frequency table backed, but
there are cases where it's impractical to use a frequency table for
certain clocks (such as the FSIDIV case, which supports 65535 divisors),
and we wish to reuse the same rate rounding algorithm.This breaks out the core of the rate rounding logic in to its own helper
routine and shuffles the frequency table logic around, switching to using
an iterator for the generic helper routine.Signed-off-by: Paul Mundt

This implements support for ioremapping of register windows that
encapsulate clock control registers used by a struct clk, with
transparent sibling inheritance.Root clocks at the top of a given topology often encapsulate the entire
register space of all of their sibling clocks, so this mapping can be
done once and handed down. A given clock enable/disable case maps out to
a single bit in a shared register, so this prevents creating multiple
overlapping mappings.The mapping case breaks down in to a couple of different situations:
- Sibling clocks without a specific mapping.
- Root clocks without a specific mapping.
- Any of sibling/root clocks with a specific mapping.Sibling clocks with no specified mapping will grovel up the clock chain
and install the root clock mapping unconditionally at registration time.Root clocks without their own mappings have a dummy BSS-initialized
mapping inserted that is handed down the chain just like any other
mapping. This permits all of the sibling clock ops to read/write using
the mapping offsets without any special configuration, enabling them to
not care whether access ultimately goes through translatable or
untranslatable memory.Any clock with its own mapping will have the window initialized at
registration time and be ready for use by its clock ops. Failure to
establish the mapping will prevent registration, so no additional sanity
checks are needed. Sibling clocks that double as parents for the moment
will not propagate their mapping down, but this is easily tunable if the
need arises.All clock mappings are kref refcounted, with each instance of mapping
inheritance incrementing the refcount.Tested-by: Kuninori Morimoto
