Linus Torvalds cf4af01221 ARM: arm-soc: Board updates for 3.8
This branch contains a set of various board updates for ARM platforms.
 
 A few shmobile platforms that are stale have been removed, some
 defconfig updates for various boards selecting new features such as
 pinctrl subsystem support, and various updates enabling peripherals, etc.

Rafael J. Wysocki 35f2b0bd59 ARM: shmobile: Move definition of shmobile_init_late() to header
The role of the only function in the common.c file in
arch/arm/mach-shmobile, shmobile_init_late(), is to call two
initializers whose definitions depend on kernel configuration
options.  Those initializers may very well be called from a static
inline function in arm/mach-shmobile/include/mach/common.h,
though, in which makes the code a bit easier to read.  Moreover,
the common.c may be dropped entirely then.

Linus Torvalds f465d145d7 arm-soc: sweeping late_initcall cleanup
This is a patch series from Shawn Guo that moves from individual
 late_initcalls() to using a member in the machine structure to invoke
 a platform's late initcalls.
 
 This cleanup is a step in the move towards multiplatform kernels since
 it would reduce the need to check for compatible platforms in each and
 every initcall.

Linus Torvalds f6a26ae769 arm-soc: board specific changes
While we generally attempt to get rid of board specific files and replace
 them with device tree based descriptions, a lot of platforms have not
 come that far:
 
 In shmobile, we add two new board files because their recently started
 effort to add DT support has not proceeded enough to use it for all of
 the important hardware.
 
 In Kirkwood, we are adding support for new boards with a combination of
 DT and board file contents in multiple cases.
 
 pxa/mmp and imx are extending support for existing board files but not
 adding new ones.

Magnus Damm bd5a875d90 mach-shmobile: Emma Mobile EV2 SMP support V3
This is V3 of Emma Mobile EV2 SMP support.

At this point only the most basic form of SMP operation
is supported. TWD and CPU Hotplug support is excluded.

Tied to both the Emma Mobile EV2 and the KZM9D board
due to the need to switch on board in platsmp.c and
the newly introduced need for static mappings.

The static mappings are needed to allow hardware
acces early during boot when SMP is initialized.
This early requirement forces us to also map in
the SMU registers.

Magnus Damm f40aaf6da1 ARM: mach-shmobile: r8a7779 SMP support V3
This patch contains r8a7779 SMP support V3 - now including
CPU hotplug offine and online support. The r8a7779 power
domain code is tied together with SMP glue code which allows
us to control the power domains via CPU hotplug.

At this point the kernel boots with the 4 Cortex-A9 cores in
SMP mode and all CPU cores except CPU0 can be hotplugged.

The code in platsmp.c is quite far from pretty, but it is
kept like that intentionally to avoid creating layers of
code that will go away in the near future anyway. The code
needs to be updated when some per-SoC handling code will be
added to the ARM architecture, see the following patch for
more information:

Current AG5 is using GIC - INTCS demux with

OTOH, normal INTC support as before is very enough for R8A7740,
because it is not SMP CPU.

Paul Mundt 750a7eee73 drivers: sh: Generalize runtime PM platform stub.
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.

This patch adds a shared SH-Mobile ARM specific CPUIdle
implementation supporting WFI only at this point. It
serves as a common point for late registration of the
arch-specific CPUIdle code, and supports adding extra
sleep modes using the callback shmobile_cpuidle_setup()
together with shmobile_cpuidle_modes[].

Add sh7372 Core Standby sleep mode support and tie it
in with the shared SH-Mobile ARM suspend code.

The Core Standby mode is the lightest sh7372-specific
sleep mode, cutting power to the ARM core excluding the
L2 cache. Any interrupt source can be used for wakeups.

The low level portion of this code is based on the
TI OMAP sleep code in sleep34xx.S, thanks to them.

Add INTCS support for the sh73a0 processor.

The interrupts on the sh73a0 processor are managed
through controllers such as GIC, INTCS and INTCA.

The ARM cores use the GIC as primary interrupt
controller and the INTCS and INTCA are hanging off
the GIC as cascaded interrupt controllers.

Peripherals connected both to the GIC and the INTC
controllers should if possible only use the GIC.

If no GIC connection is available then INTCS and
INTCA may be used instead.

Add SMP support for ag5evm and the sh73a0 processor.

Onlining and offlining works well, but at this point
offlined processor cores are not put into sleep mode.

There is no spinlock for syncing the secondary core
with the first one in this implementation. The code
instead relies on the cpu_online() check in __cpu_up().

Add SMP base support for R-Mobile / SH-Mobile processors.

This patch contains all base code to support CONFIG_SMP
regardless of ARCH_SHMOBILE processor type. Both local timer

code is included.

At this point only the default behavior is in place, so
a single core will always be used even though CONFIG_SMP
is enabled on multicore systems.

The SMP Kconfig entry for arch/arm/Kconfig is excluded from
this patch to simplify merging.

Magnus Damm 6d9598e24d ARM: mach-shmobile: Initial AG5 and AG5EVM support
This patch adds initial support for Renesas SH-Mobile AG5.

At this point the AG5 CPU support is limited to the ARM
core, SCIF serial and a CMT timer together with L2 cache
and the GIC. The AG5EVM board also supports Ethernet.

Future patches will add support for GPIO, INTCS, CPGA
and platform data / driver updates for devices such as
IIC, LCDC, FSI, KEYSC, CEU and SDHI among others.

The code in entry-macro.S will be cleaned up when the
ARM IRQ demux code improvements have been merged.

Depends on the AG5EVM mach-type recently registered but
not yet present in arch/arm/tools/mach-types.

As the AG5EVM board comes with 512MiB memory it is
recommended to turn on HIGHMEM.
