Now that all of the named string association with clocks has been
migrated to clkdev lookups there's no meaningful named topology that can
be constructed for a debugfs tree view. Get rid of the left over bits,
and shrink struct clk a bit in the process.Signed-off-by: Paul Mundt

The runtime PM platform support stub in use by ARM-based SH/R-Mobile
platforms contains nothing that's specifically ARM-related and instead of
wholly generic to anything using the clock framework.The recent runtime PM changes interact rather badly with the lazy
disabling of clocks late in the boot process through the clock framework,
leading to situations where the runtime suspend/resume paths are entered
without a clock being actively driven due to having been lazily gated
off.In order to correct this we can trivially tie in the aforementioned stub
as a general fallback for all SH platforms that don't presently have
their own runtime PM implementations (the corner case being SH-based
SH-Mobile platforms, which have their own stub through the hwblk API --
which in turn has bitrotted and will be subsequently adapted to use the
same stub as everyone else), regardless of whether the platforms choose
to define power domains of their own or not.This fixes up regressions for clock framework users who also build in
runtime PM support without any specific power domains of their own, which
was previously causing the serial console to be lost when warring with
lazy clock disabling.Signed-off-by: Paul Mundt

Add GPIO IRQ support to the shared PFC code in drivers/sh/pfc.c

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
