Pull ARM SoC fixes from Arnd Bergmann:
"We have various small DT fixes, and one important regression fix:
The recent device tree bugfixes that were intended to address issues
that 'dtc' started warning about in 4.15 fixed various USB PHY device
nodes, but it turns out that we had code that depended on those nodes
being incorrect and the probe failing with a particular error code.
With the workaround we can also deal with correct device nodes.
The DT fixes include:
- Allwinner A10 and A20 had the display pipeline set up incorrectly
(introduced in v4.15)
- The Altera PMU lacked an interrupt-parent (never worked)
- Pin muxing on the Openblocks A7 (never worked)
- Clocks might get set up wrong on Armada 7K/8K (4.15 regression)
We now have additional device tree patches to address all the
remaining warnings introduced in 4.15, but decided to queue them for
4.16 instead, to avoid risking another regression like the USB PHY
thing mentioned above.

Since AVR32 arch is gone, atmel-wm97xx driver is useless. In theory it
could have been rewritten to work with AT91 devices, but the driver is from
the platform data era, and a bit hard coded to work on AVR32 hardware
variant of the AC97C peripheral, so let's remove it.

Stefan Wahren reports a problem with a warning fix that was merged
for v4.15: we had lots of device nodes with a 'phys' property pointing
to a device node that is not compliant with the binding documented in
Documentation/devicetree/bindings/phy/phy-bindings.txt
This generally works because USB HCD drivers that support both the generic
phy subsystem and the older usb-phy subsystem ignore most errors from
phy_get() and related calls and then use the usb-phy driver instead.
However, it turns out that making the usb-nop-xceiv device compatible with
the generic-phy binding changes the phy_get() return code from -EINVAL to
-EPROBE_DEFER, and the dwc2 usb controller driver for bcm2835 now returns
-EPROBE_DEFER from its probe function rather than ignoring the failure,
breaking all USB support on raspberry-pi when CONFIG_GENERIC_PHY is
enabled. The same code is used in the dwc3 driver and the usb_add_hcd()
function, so a reasonable assumption would be that many other platforms
are affected as well.
I have reviewed all the related patches and concluded that "usb-nop-xceiv"
is the only USB phy that is affected by the change, and since it is by far
the most commonly referenced phy, all the other USB phy drivers appear
to be used in ways that are are either safe in DT (they don't use the
'phys' property), or in the driver (they already ignore -EPROBE_DEFER
from generic-phy when usb-phy is available).
To work around the problem, this adds a special case to _of_phy_get()
so we ignore any PHY node that is compatible with "usb-nop-xceiv",
as we know that this can never load no matter how much we defer. In the
future, we might implement a generic-phy driver for "usb-nop-xceiv"
and then remove this workaround.
Since we generally want older kernels to also want to work with the
fixed devicetree files, it would be good to backport the patch into
stable kernels as well (3.13+ are possibly affected), even though they
don't contain any of the patches that may have caused regressions.

Some distributions have turned on the reset attack mitigation feature,
which is designed to force the platform to clear the contents of RAM if
the machine is shut down uncleanly. However, in order for the platform
to be able to determine whether the shutdown was clean or not, userspace
has to be configured to clear the MemoryOverwriteRequest flag on
shutdown - otherwise the firmware will end up clearing RAM on every
reboot, which is unnecessarily time consuming. Add some additional
clarity to the kconfig text to reduce the risk of systems being
configured this way.

When a new LPM tree is created, we try to replace the trees in the
existing virtual routers with it. If we fail, the tree needs to be
freed.
Currently, this does not happen in the unlikely case where we fail to
bind the tree to the first virtual router, since its reference count
never transitions from 1 to 0.
Fix that by taking a reference before binding the tree.

Commit bbb163e18960 ("drm/nouveau/bar: implement bar1 teardown")
introduced add a teardown helper function for BAR1. During
initialisation of the Nouveau, initially all the teardown helpers are
called once, before calling their init counterparts. For gk20a, after
the BAR1 teardown function is called, the device is hanging during the
initialisation of the FB sub-device. At this point it is unclear why
this is happening and this is still under investigation. However, this
change is preventing Tegra124 devices from booting when Nouveau is
enabled. To allow Tegra124 to boot, remove the teardown helper for
gk20a.
This is based upon a previous patch by Guillaume Tucker but limits
the workaround to only gk20a GPUs.

add this for correctly updating global mem count in ttm_mem_zone.
before that when ttm_mem_global_alloc_page fails, we would update all
dma_page's global mem count in ttm_dma->pages_list. but actually here
we should not update for the last dma_page.
v2: only the update of last dma_page is not right
v3: use lower bits of dma_page vaddr

A cleanup of the PM code left an incorrect #ifdef in place, leading
to a harmless build warning:
drivers/net/ethernet/intel/fm10k/fm10k_pci.c:2502:12: error: 'fm10k_suspend' defined but not used [-Werror=unused-function]
drivers/net/ethernet/intel/fm10k/fm10k_pci.c:2475:12: error: 'fm10k_resume' defined but not used [-Werror=unused-function]
It's easier to use __maybe_unused attributes here, since you
can't pick the wrong one.

When saving BOs in the hang state we skip one entry of the
kernel_state->bo[] array, thus leaving it to NULL. This leads to a NULL
pointer dereference when, later in this function, we iterate over all
BOs to check their ->madv state.

If the frame samples from a render target that was just written, its
cache flush during the binning step may have occurred before the
previous frame's RCL was completed. Flush the texture caches again
before starting each RCL job to make sure that the sampling of the
previous RCL's output is correct.

This patch does not change any functionality but makes srpt_cm_req_recv()
independent of the IB/CM and hence simplifies the patch that introduces
RDMA/CM support.
