Fix build regression introduced by commit 056879d2f244001b2888cdc8cf
(ARM: mach-shmobile: sh7372 A3SP no_suspend_console fix) by moving
the intialization of the A3SP domain to a separate function and
providing an empty definition of it for CONFIG_PM unset.Reported-and-tested-by: Guennadi Liakhovetski

The SH7372 PM domain initialization routine calls pd_power_up()
that executes the domain's .resume() callback, if present, and for
the A4R domain this callback attepmts to restore the INTCS state from
uninitialized data. To avoid that, introduce __pd_power_up() that
will only execute the domain's .resume() callback if its second
argument is 'true' and make the SH7372 PM domain initialization
use it with 'false' as its second argument. Redefine pd_power_up()
as a wrapper around __pd_power_up().Reported-by: Guennadi Liakhovetski

setup_processor copies the arch_name and elf_name fields out of the
selected proc_info_list into two fixed size buffers.Since the proc_info_list structure is defined in a proc_*.S assembly
file, this can lead to subtle errors if the strings defined there are
too long (for example, corrupting the machine ID).This patch uses snprintf instead of sprintf to ensure that these buffers
are not overrun.Signed-off-by: Will Deacon

The following commits break cpuidle on SH-Mobile ARM:
46bcfad cpuidle: Single/Global registration of idle states
e978aa7 cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_stateThis patch remedies these issues by up-porting the SH-Mobile
code to fit with the above introduced framework changes.It is worth noting that the new code becomes significantly cleaner,
so these framework changes are very welcome. At the same time this
breakage could probably have been avoided by grepping for "last_state"
and "cpuidle_register_driver".Signed-off-by: Magnus Damm

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

If "no_suspend_irq" is used on the sh7372 Mackerel board
with v3.2-rc1 then Suspend-to-RAM fails because the serial
console tries to write to the SCIF driver even though the
power domain is turned off.This patch checks the state of "console_suspend_enabled"
to see if A3SP should be forced enabled.Signed-off-by: Magnus Damm

*_pinmux_init() register the GPIO and pinmux devices so that they're ready
before any other device needs them.*_pinmux_init() are also called by board-dt.c in order to set up the GPIO
and pinmux configurations. In this case, if we register the devices, they
end up being probed once due to this registration, and a second time due
to a device-tree node (or vice-versa). The second probe fails since the
memory regions are already requested. Besides, we don't actually want the
duplicated devices.To avoid this duplicate registration, modify *_pinmux_init() to check
whether it's running on a DT machine. If not, register the pinmux devices.
If so, don't register them.Finally, modify board-dt.c to call the *_pinmux_init() after all devices have
been instantiated from device-tree. This allows the GPIO and pinmux devices
to be instantiated and initialized before calling functions to configure the
hardware.This has one disadvantage: The pinmux and GPIO initialization now happens
after /all/ devices are instantiated, rather than after just gpio and
pinmux but before anything else. So the correct HW configuration is not
in place when e.g. the SD/MMC device is probed. Long-term, this should be
solved by doing both:a) Initializing the HW state from DT nodes during GPIO and pinmux device
probe.
b) Using the deferred driver probe mechanism, so that drivers can defer
their probe until after the gpio and pinmux drivers have probed.v2: s/int is_dt/bool is_dt/
v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing
an explicit parameter into the function from outside.Signed-off-by: Stephen Warren
