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.

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: NRafael J. Wysocki <rjw@sisk.pl> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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.

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.

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. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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.

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.

This splits up the sh intc core in to something more vaguely resembling a subsystem. Most of the functionality was alread fairly well compartmentalized, and there were only a handful of interdependencies that needed to be resolved in the process. This also serves as future-proofing for the genirq and sparseirq rework, which will make some of the split out functionality wholly generic, allowing things to be killed off in place with minimal migration pain.

Many interrupts that share a single mask source but are on different hardware vectors will have an associated register tied to an INTEVT that denotes the precise cause for the interrupt exception being triggered. This introduces the concept of IRQ subgroups in the intc core, where a virtual IRQ map is constructed for each of the pre-defined cause bits, and a higher level chained handler takes control of the parent INTEVT. This enables CPUs with heavily muxed IRQ vectors (especially across disjoint blocks) to break things out in to a series of managed chained handlers while being able to dynamically lookup and adopt the IRQs created for them. This is largely an opt-in interface, requiring CPUs to manually submit IRQs for subgroup splitting, in addition to providing identifiers in their enum maps that can be used for lazy lookup via the radix tree.
