into irq/core
Pull irqchip core changes for v4.6 from Jason Cooper:
- mvebu (armada-370-xp)
- MSI support
- Deconflict with mvebu's arm64 code
- ts4800
- Restrict when ts4800 driver can be built
- Make ts4800_ic_ops static const
- bcm2836: Drop superfluous memory barrier

Moving an SPI around doesn't require any extra work from the rest
of the stack, and specially not for MSI-generated SPIs.
It is then worth returning IRQ_SET_MASK_OK_DONE instead of
IRQ_SET_MASK_OK, and simplify the other irqchips that rely on
this behaviour (GICv2m and Marvell's ODMI controller).

This commits adds a new irqchip driver that handles the ODMI
controller found on Marvell 7K/8K processors. The ODMI controller
provide MSI interrupt functionality to on-board peripherals, much like
the GIC-v2m.

The driver stays the same but the initialization changes a bit.
For OF boards we now get the memory map from the OF node and use
a linear mapping instead of the legacy mapping. For legacy boards
we still use a legacy mapping and just pass down all the parameters
from the board init code.

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.

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

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().

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>/.

Pull ARM SoC fixes from Olof Johansson:
"The first real batch of fixes for this release cycle, so there are a
few more than usual.
Most of these are fixes and tweaks to board support (DT bugfixes,
etc). I've also picked up a couple of small cleanups that seemed
innocent enough that there was little reason to wait (const/
__initconst and Kconfig deps).
Quite a bit of the changes on OMAP were due to fixes to no longer
write to rodata from assembly when ARM_KERNMEM_PERMS was enabled, but
there were also other fixes.
Kirkwood had a bunch of gpio fixes for some boards. OMAP had RTC
fixes on OMAP5, and Nomadik had changes to MMC parameters in DT.
All in all, mostly the usual mix of various fixes"

This is needed to properly deallocate port payload
after downstream branch get unplugged.
In order to do this unplugged MST topology should
be preserved, to find first alive port on path to
unplugged MST topology, and send payload deallocation
request to branch device of found port.
For this mstb and port kref's are used in reversed
order to track when port and branch memory could be
freed.
Added additional functions to find appropriate mstb
as described above.

Previous implementation does not handle case below: boot up one MST branch
to DP connector of ASIC. After boot up, hot plug 2nd MST branch to DP output
of 1st MST, GUID is not created for 2nd MST branch. When downstream port of
2nd MST branch send upstream request, it fails because 2nd MST branch GUID
is not available.
New Implementation: only create GUID for MST branch and save it within Branch.

1. Get edid for all connected MST displays, not only on logical ports,
in the same thread as MST topology detection is done:
There are displays that have branches inside w/o logical ports.
So in case another SST display connected downstream system can
end-up in situation when 3 DOWN requests sent: two for
‘remote i2c read’ and one for ‘enum path resources’, making slots full.
2. Call notification callback in one place in the end of topology discovery/update:
This is done to reduce number of events sent to userspace in case complex
topology discovery is going, adding multiple number of connectors;
3. Remove notification callback call from short pulse interrupt processing function:
This is done in order not to block interrupt processing function, in case any
MST request will be made from it. Notification will be send from topology
discovery/update work item.

Our PBN value overflows the 20 bits integer part of the 20.12
fixed point. We need to use 31.32 fixed point to avoid this.
This happens with display clocks larger than 293122 (at 24 bpp),
which we see with the Sharp (and similar) 4k tiled displays.

max_payload is limited by the space we have in
drm_dp_mst_topology_mgr::vcpi_mask,payload_mask. We need to track
max_payloads+1 IDs in these masks, see drm_dp_mst_assign_payload_id().
Add a sanity check for this.

xhci_find_next_ext_cap doesn't check for PCI hotplug removal and may use
the PCI master abort bit pattern (~0) to calculate a new PCI address
offset to read/write. The has lead to reproducable crashes when testing
surprise removal during device initialization on a Stratus platform, at
least after commit d5ddcdf4d672 ("xhci: rework xhci extended capability
list parsing functions").
The crash is repeatable on a Stratus platform when injecting hardware
faults to induce xHCI host controller hotplug during driver
initialization. If a PCI read in xhci_find_next_ext_cap returns the
master abort pattern, quirk_usb_handoff_xhci may start using a bogus
ext_cap_offset to start searching more bogus PCI addresses.

DWC3 got a fix for OTG Certification, DWC2 has two fixes for regressions on
RasPI, MUSB has a NULL pointer dereference fix for ux500 platforms and two
PHYs (MSM and MXS) got some minor fixes.
While at that, I'm also adding a fix to my email address which has changed
