c7e1d89b34 Merge tag 'samsung-soc64-4.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/arm64
Samsung Exynos ARM64 improvements for v4.6:
1. Remove separate ARCH_EXYNOS7 symbol and consolidate it into
   one ARCH_EXYNOS.

This depends on clk tree: removal of last presence of ARCH_EXYNOS7.

c87b3e970c arm64: EXYNOS: Consolidate ARCH_EXYNOS7 symbol into ARCH_EXYNOS
The ARMv8 Exynos family SoCs in Linux kernel are currently:
 - Exynos5433 (controlled by ARCH_EXYNOS),
 - Exynos7 (controlled by ARCH_EXYNOS7).

It duplicates Kconfig symbols unnecessarily, so consolidate them into
one ARCH_EXYNOS. Future SoCs could fall also under the ARCH_EXYNOS
symbol.

The commit should not bring any visible functional change.

Currently the Exynos5433 (ARMv8 SoC) clock driver depends on ARCH_EXYNOS
so it is built also on ARMv7. This does not bring any kind of benefit.
There won't be a single kernel image for ARMv7 and ARMv8 SoCs (like
multi_v7 for ARMv7).

Instead build clock drivers only for respective SoC's architecture.

2859f70a0c Documentation: arm: update Marvell product listing
I'm still getting confused regarding which core specifically
is used in which SoC, so I've added some more detail to the
Marvell README file. I got most of this from random sources
on the internet, so it's possible that some of the information
is wrong, but most of it should be pretty obvious.

There are a few remaining points I could not find out:

* The CPU core in Orion 88F6183
* The difference (if any) between PJ4B-MP and PJ4C
* The naming of Feroceon/Jolteon/Flareon/Sheeva/Mohawk/PJ1/PJ4
  is still confusing, as they tend to overlap.

 - move Armada SP out from the EBU family into its own "Storage"

 - fixed the URL for the Armada SP information, since the link of the

 - explicitly indicate that there is no support in upstream for the

 - indent the "Core: " description for the Armada XP to be clearly

2ee98234b8 arm64: renesas: Enable PM and PM_GENERIC_DOMAINS for SoCs with PM Domains
All supported Renesas ARM64 SoCs have clock and power domains. To ensure
proper operation of on-SoC modules, module clocks must be ungated, and
power domains must be powered up when needed.

Currently the user can choose to build a kernel with power management
enabled or disabled:
  - If CONFIG_PM=y, power domains and/or module clocks are handled
    dynamically by Runtime PM and the generic power domain.
  - If CONFIG_PM=n, power domains are assumed to be powered up by reset
    state or by the boot loader, and module clocks are handled by the
    legacy clock domain on driver (un)bind.
    The latter is implemented using a platform bus notifier, which
    applies not only to all on-SoC devices, but to all platform devices
    present in the system.

To remove the dependency on implicit assumptions, and to get rid of the
peculiarities of the legacy clock domain, enable CONFIG_PM and
CONFIG_PM_GENERIC_DOMAINS unconditionally.

a71916b027 Documentation: arm: update supported Marvell EBU processors
Now that we support Armada 37xx, let's add this family of SoC to the
Marvell documentation, and a reference to a link with more details about
those processors. As for Armda 39x, no datasheet is publicly
available at this time.

63131b636a irqchip/armada-370-xp: Do not enable it by default when ARCH_MVEBU is selected
The irq-armada-370-xp driver can only be built for ARM 32 bits. The mvebu
family had grown with a new ARM64 SoC which will also select the
ARCH_MEVBU configuration. Since "ARM: mvebu: use the ARMADA_370_XP_IRQ
option", the ARM32 mvebu SoC directly select this new option. Selecting
it by default when ARCH_MEVBU is selected is no more needed.

This patch removes this dependency, thanks to this, a kernel for ARM64
mvebu SoC can be built without error due this driver.

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.

In order to make the output of /proc/interrupts, use shorter names for
the irq_chip registered by the irq-armada-370-xp driver. Using capital
letters also matches better what is done for the GIC driver, which
uses just "GIC" as the irq_chip->name.

fcc392d501 irqchip/armada-370-xp: Use the generic MSI infrastructure
This commit moves the irq-armada-370-xp driver from using the
PCI-specific MSI infrastructure to the generic MSI infrastructure, to
which drivers are progressively converted.

In this hardware, the MSI controller is directly bundled inside the
interrupt controller, so we have a single Device Tree node to which
multiple IRQ domaines are attached: the wired interrupt domain and the
MSI interrupt domain. In order to ensure that they can be
differentiated, we have to force the bus_token of the wired interrupt
domain to be DOMAIN_BUS_WIRED. The MSI domain bus_token is
automatically set to the appropriate value by
pci_msi_create_irq_domain().

fed6d33631 irqchip/armada-370-xp: Add Kconfig option for the driver
Instead of building the irq-armada-370-xp driver directly when
CONFIG_ARCH_MVEBU is enabled, this commit introduces an intermediate
CONFIG_ARMADA_370_XP_IRQ hidden Kconfig option.

This allows this option to select other interrupt-related Kconfig
options (which will be needed in follow-up commits) rather than having
such selects done from arch/arm/mach-<foo>/.
