33c45ef8ad ARM: mvebu: Select corediv clk for all mvebu v7 SoC
Since the commit bd3677ff31 ("clk: mvebu: Remove corediv clock from
Armada XP"), the corediv clk is no more selected for Armada XP, however
this clock is used for Armada XP using the compatible
armada-370-corediv-clock.

While since commit 1594d568c6 ("clk: mvebu: Move corediv config to
mvebu config") Armada 38x and Armada 375 got corediv support again, not
only Armada XP was missed but also Armada 39x.

Actually all the SoC selecting MVEBU_V7 config need this clock:
git grep "\-corediv-clock" arch/arm/boot/dts
arch/arm/boot/dts/armada-370-xp.dtsi: compatible = "marvell,armada-370-corediv-clock";
arch/arm/boot/dts/armada-375.dtsi:    compatible = "marvell,armada-375-corediv-clock";
arch/arm/boot/dts/armada-38x.dtsi:    compatible = "marvell,armada-380-corediv-clock";
arch/arm/boot/dts/armada-39x.dtsi:    compatible = "marvell,armada-390-corediv-clock"

This commit now fixes this behavior by letting MVEBU_V7 select
MVEBU_CLK_COREDIV.

5c34a4e89c ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

1594d568c6 clk: mvebu: Move corediv config to mvebu config
The core clock does not depend on corediv, so enabling corediv
based on the clock is not really correct.  Move the corediv
config option from the clock driver Kconfig to the mvebu Kconfig
so that it can be enabled by the MACH option instead.

This also enables corediv on Armada 375 and 38X, which was
previously missing.

cb49d86dbe ARM: mvebu: Use the ARMADA_370_XP_IRQ option
Now that there is a ARMADA_370_XP_IRQ option to enable the irqchip
driver for Armada 370, XP, 375, 38x and 39x, let's select this option
when needed. Note that this selection is currently not mandatory
because ARMADA_370_XP_IRQ is for now always enabled when ARCH_MVEBU=y,
but this is something that we will change in the future, and therefore
we should make the relevant platforms select ARMADA_370_XP_IRQ when
needed.

Due to this, selecting GENERIC_IRQ_CHIP is no longer needed.

e324654294 ARM: use "depends on" for SoC configs instead of "if" after prompt
Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.

Please notice the difference between

    config ARCH_FOO
            bool "Foo SoCs" if ARCH_MULTI_V7

and

    config ARCH_FOO
            bool "Foo SoCs"
            depends on ARCH_MULTI_V7

These two are *not* equivalent!

In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7.  So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns.  This is probably not what
you want.

The former should be used only when you need to do so, and you really
understand what you are doing.  (In most cases, it should be wrong!)

For enabling/disabling sub-architectures, the latter is always correct.

As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).

[Arnd: I note that there is not really a bug here, according to
 the discussion that followed, but I can see value in being consistent
 and in making the lines shorter]

44e259ac90 ARM: dove: create a proper PMU driver for power domains, PMU IRQs and resets
The PMU device contains an interrupt controller, power control and
resets.  The interrupt controller is a little sub-standard in that
there is no race free way to clear down pending interrupts, so we try
to avoid problems by reducing the window as much as possible, and
clearing as infrequently as possible.

The interrupt support is implemented using an IRQ domain, and the
parent interrupt referenced in the standard DT way.

The power domains and reset support is closely related - there is a
defined sequence for powering down a domain which is tightly coupled
with asserting the reset.  Hence, it makes sense to group these two
together, and in order to avoid any locking contention disrupting this
sequence, we avoid the use of syscon or regmap.

This patch adds the core PMU driver: power domains must be defined in
the DT file in order to make use of them.  The reset controller can
be referenced in the standard way for reset controllers.

242ede0bdd ARM: mvebu: add core support for Armada 39x
This commit adds the core support for Armada 39x, which is quite
simple:

 - a new Kconfig option which selects the appropriate clock and
   pinctrl drivers as well as other common features (GIC, L2 cache,
   SMP, etc.)

 - a new DT_MACHINE_START which references the top-level compatible
   strings supported for the Marvell Armada 39x.

 - a new SMP enable-method. The mechanism to enable CPUs for Armada
   39x appears to be the same as Armada 38x. However, we do not want
   to use marvell,armada-380-smp in the Device Tree, in the case of
   the discovery of a subtle difference in the future, which would
   require changing the Device Tree. And the enable-method isn't a
   compatible string: you can't specify several values and expect a
   fallback on the second string if the first one isn't
   supported. Therefore, we simply declare the SMP enable method
   "marvell,armada-390-smp" as doing the same thing as the
   "marvell,armada-380-smp" one.

52fcc56753 ARM: mvebu: select ARM_CPU_SUSPEND for Marvell EBU v7 platforms
On Marvell Armada platforms, the PMSU (Power Management Service Unit)
controls a number of power management related activities, needed for
things like suspend/resume, CPU hotplug, cpuidle or even simply SMP.

Since cpuidle support was added for Armada XP, the pmsu.c file in
arch/arm/mach-mvebu/ calls the cpu_suspend() and cpu_resume() ARM
functions, which are only available when
CONFIG_ARM_CPU_SUSPEND=y. Therefore, configurations that have
CONFIG_ARM_CPU_SUSPEND disabled due to PM_SLEEP being disabled no
longer build properly, due to undefined references to cpu_suspend()
and cpu_resume().

To fix this, this patch simply ensures CONFIG_ARM_CPU_SUSPEND is
always enabled for Marvell EBU v7 platforms. Doing things in a more
fine-grained way would require a lot of #ifdef-ery in pmsu.c to
isolate the parts that use cpu_suspend()/cpu_resume(), and those parts
would anyway have been needed as soon as either one of suspend/resume,
CPU hotplug or cpuidle was enabled.

ed2d859119 ARM: mvebu: Fix broken SoC ID detection
Currently the mvebu boards need to detect the SoC revision in order to apply
some quirks needed to workaround issues found on I2C and thermal controllers
present only in very early SoC.

This detection requires PCI address translation to work, so we need to
explicitly select OF_ADDRESS_PCI.

This can be considered a partial revert of the following commit, that
wrongly removed the option selection:

This config exists entirely to hide the cpufreq menu from the

is actually built if this config is 'Y' and it just leads to more
patches that add a select under a platform Kconfig so that some
other CPUfreq option can be chosen. Let's remove the option so
that we can always enable CPUfreq drivers on ARM platforms.

825f4e0271 ARM: SoC updates for 3.16 (part 1)
A quite large set of SoC updates this cycle. In no particular order:
 
 - Multi-cluster power management for Samsung Exynos, adding support for
   big.LITTLE CPU switching on EXYNOS5
 - SMP support for Marvell Armada 375 and 38x
 - SMP rework on Allwinner A31
 - Xilinx Zynq support for SOC_BUS, big endian
 - Marvell orion5x platform cleanup, modernizing the implementation and
   moving to DT.
 - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
   that their platform can be enabled in the same kernel binary as most
   of the other v7 platforms in the tree. \o/ The work isn't quite complete,
   there's some driver fixes still needed, but the basics now work.
 
 New SoC support added:
 - Freescale i.MX6SX
 - LSI Axxia AXM55xx SoCs
 - Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800
 - STi STIH407
 
 Plus a large set of various smaller updates for different platforms. I'm
 probably missing some important one here.

1ee89e2231 ARM: mvebu: add SMP support for Armada 375 and Armada 38x
This commit adds the SMP support for Armada 375 and Armada 38x. It
turns out that the SMP logic for both of these SOCs are fairly
similar, the only differences being:

 * A different method to set the secondary CPU boot address

 * An Armada 375 specific workaround needed for the early Z1 stepping,
   added by the following patch.

Other than that, the patch is fairly straightforward and adds the
usual platsmp and headsmp code, defining the smp_operations structure
that is referenced from the DT_MACHINE structures.

8e6ac20338 ARM: mvebu: enable the ARM SCU on Armada 375 and Armada 38x
Contrary to the Armada 370 and XP that used the PJ4B Marvell cores,
the Armada 375 and Armada 38x use the ARM Cortex-A9. A consequence of
this is that the unit responsible for the coherency between CPUs is
now the ARM SCU, and not the Marvell coherency unit (which is still
present to do coherency with I/O devices).

Therefore this commit:

 * Ensures that the selection of the Armada 375 or Armada 38x SoC
   support enables the ARM SCU support in the kernel.

 * Make sure to initialize the SCU at boot time.

c7f094d5e8 ARM: mvebu: don't select CONFIG_NEON
CONFIG_NEON is meant to be user-selectable. Turning it on
unconditionally means we can't build a smaller kernel when
we don't need it, and causes build errors if CONFIG_VFP
is not also enabled.

To still have neon enabled however, we need to turn it on
now in multi_v7_defconfig and mvebu_v7_defconfig.

Move the kirkwood DT support into mach-mvebu, and make them part of
ARCH_MULTI_V5. Minimal changes have been made in order to make it
boot. Cleanup of the header files and integration with mvebu will
take place in following patches.

In order to help Debian transition between mach-kirkwood and
mach-mvebu, the DTS files are compiled for both, allowing Debian to
continue using mach-kirkwood until all remaining boards are supported
by mach-mvebu. Debian is then expected to simply swap from
mach-kirkwood to mach-mvebu and mach-kirkwood will be removed.

9aa30f1c13 ARM: mvebu: add initial support for the Armada 380/385 SOCs
This commit adds the basic support for the Armada 380 and Armada 385
SOCs. These SoCs share most of their IP with the Armada 370/XP
SoCs. The main difference is the use of a Cortex A9 CPU instead of the
PJ4B CPU. The Armada 380 is a single core Cortex-A9, while the Armada
385 is a dual-core Cortex-A9.

The support is introduced in board-v7.c, together with Armada 370/XP,
but a separate DT structure is added, because Armada 38x will need a
different set of SMP operations when the SMP support is introduced.

99b3d29462 ARM: mvebu: rename armada-370-xp.c to board-v7.c
In preparation to the introduction of the support of Armada 375 and
Armada 38x, this commit renames arch/arm/mach-mvebu/armada-370-xp.c to
arch/arm/mach-mvebu/board-v7.c. The board-v7.c name as we expect this
file to ultimately contain the DT_MACHINE_START definitions for all
ARMv7 Marvell EBU platforms (370, 375, 38x, XP and Dove as of today).

In relation to this file rename, this commit also:

 * Renames the hidden Kconfig symbol MACH_ARMADA_370_XP to
   MACH_MVEBU_V7. This hidden symbol is selected by the various
   per-SoC visible Kconfig options to trigger the build of board-v7.c.

 * Renames a certain number of functions in board-v7.c so that their
   armada_370_xp prefix is replaced by a mvebu prefix. The .dt_compat
   array keeps its armada_370_xp prefix because the new SOCs will be
   introduced with separate .dt_compat arrays, due to the need for
   different SMP operations.
