After recent ACPI core changes acpi_bus_get_device() will always
succeed for dock station ACPI device objects, so show_docked()
should not use that function's return value as an indicator of
whether or not the dock device is present.
Make it use acpi_device_enumerated() for this purpose.

Pull IOMMU fixes from Joerg Roedel:
"The fixes are only for the ARM-SMMU driver. Here is the summary from
Will Deacon:
- Andreas Herrmann took the driver for a run with a real SATA
controller, which caused the new mutex-based locking to explode
since we require mappings in atomic context
- Yifan fixed an issue with the page table creation, which then
caused breakages with the way in which we flush descriptors out to
the table walker
- I ran the driver on a system where the SMMU is hooked into a
coherent interconnect for table walks, and noticed a shareability
mismatch between the CPU and the SMMU
These issues are all fixed here and have been tested on both arm and
arm64 based systems.
Besides that I put a fix on-top to make the spinlock irq-safe, so that
the code-paths can be used in the DMA-API"

Whilst trying to bring-up an SMMUv2 implementation with the table
walker plumbed into a coherent interconnect, I noticed that the memory
transactions targetting the CPU caches from the SMMU were marked as
outer-shareable instead of inner-shareable.
After a bunch of digging, it seems that we actually need to program
CBARn.BPSHCFG for s1-s2-bypass contexts to act as non-shareable in order
for the shareability configured in the corresponding TTBCR not to be
overridden with an outer-shareable attribute.

Now that we populate page tables as we traverse them ("iommu/arm-smmu:
fix pud/pmd entry fill sequence"), we need to ensure that we flush out
our zeroed tables after initial allocation, to prevent speculative TLB
fills using bogus data.
This patch adds additional calls to arm_smmu_flush_pgtable during
initial table allocation, and moves the dsb required by coherent table
walkers into the helper.

Commit a44a9791e778 ("iommu/arm-smmu: use mutex instead of spinlock for
locking page tables") replaced the page table spinlock with a mutex, to
allow blocking allocations to satisfy lazy mapping requests.
Unfortunately, it turns out that IOMMU mappings are created from atomic
context (e.g. spinlock held during a dma_map), so this change doesn't
really help us in practice.
This patch is a partial revert of the offending commit, bringing back
the original spinlock but replacing our page table allocations for any
levels below the pgd (which is allocated during domain init) with
GFP_ATOMIC instead of GFP_KERNEL.

The ARM SMMU driver's population of puds and pmds is broken, since we
iterate over the next level of table repeatedly setting the current
level descriptor to point at the pmd being initialised. This is clearly
wrong when dealing with multiple pmds/puds.
This patch fixes the problem by moving the pud/pmd population out of the
loop and instead performing it when we allocate the next level (like we
correctly do for ptes already). The starting address for the next level
is then calculated prior to entering the loop.

The front headphone and mic jackes on a HP desktop model (Vendor Id:
0x111d76c7 Subsystem Id: 0x103c2b17) can not work, the codec on this
machine has 8 physical ports, 6 of them are routed to rear jackes
and all of them work very well, while the remaining 2 ports are
routed to front headphone and mic jackes, but the corresponding
pin complex node are not defined correctly.
After apply this fix, the front audio jackes can work very well.

ASoC: Fixes for v3.14
A few fixes, all driver speccific ones. The DaVinci ones aren't as
clear as they should be from the subject lines on the commits but they
fix issues which will prevent correct operation in some use cases and
only affect that particular driver so are reasonably safe.

The commit 1abe729 (ASoC: fsl: Add missing pm to current machine
drivers) enables pm support for a few IMX machine drivers. But it does
not update dev drvdata to be the pointer to 'card'. This causes the
kernel dump below in system suspend, because snd_soc_suspend() expects
that the dev drvdata points to 'card', while it still points to the
private data of machine driver.
This patch fixes imx-sgtl5000 and imx-wm8962 by attaching 'card' to dev
drvdata and private data to card drvdata. For imx-mc13783, I simply
revert the pm change because it must be broken for the same reason and
I don't have hardware to test pm enabling code.

The use of pm_runtime in trigger() callback is not correct and it will lead
to unbalanced power.usage_count.
The only place which might need to call pm_runtime is the set_fmt callback.

These registers can be configured synchronously for playback and capture.
Furthermore when McASP is in master and sync mode the capture operation
needs the TX path to be configured in order to be able to provide the needed
clocks for the bus.
xxFMT and xxFMCT registers has been already configured for both TX and RX
other places in the driver.

Currently the I2C device Ids conflict for the MFD and CODEC so
cannot be both instantiated on one platform. This patch updates
the Ids and names to make them unique from each other.
It should be noted that the I2C addresses for both PMIC and CODEC
are modifiable so instantiation of the two are kept as separate
devices, rather than instantiating the CODEC from the MFD code.

Since the machine driver selects the CODEC driver we need to make sure that the
machine driver is only selectable if the CODEC driver can be build. This avoids
build errors under some configurations (which typically only result from
randconfig).

Incorrect ADC is picked in ca0132_capture_pcm_prepare(),
where it assumes multiple streams while there is one stream
per ADC. Note that ca0132_capture_pcm_cleanup() already does
the right thing.
The Chromebook Pixel has a microphone under the keyboard that
is attached to node id 0x8. Before this fix, recording would
always go to the main internal mic (node id 0x7).

When a HDMI stream is opened with the same stream tag
as a following opened stream to ca0132, audio will be
heard from two ports simultaneously.
Fix this issue by change to use snd_hda_codec_setup_stream
and snd_hda_codec_cleanup_stream instead, so that an
inactive stream can be marked as 'dirty' when found
with a conflict stream tag, and then get purified.

Pull PCI updates from Bjorn Helgaas:
"The most interesting thing here is the change to enable INTx (by
clearing PCI_COMMAND_INTX_DISABLE) if the BIOS left INTx disabled.
Apparently the Baytrail BIOS does this, which means EHCI doesn't work.
Also, fix an AHCI MSI regression and other issues with the recent MSI
changes. This also adds pci_enable_msi_exact() and
pci_enable_msix_exact(), which aren't regression fixes, but will keep
us from touching drivers twice (once to stop using the deprecated
pci_enable_msi(), etc., and again to use the *_exact() variants).
There's also a minor MVEBU fix.
Summary:
MSI:
- Fix AHCI single-MSI fallback (Alexander Gordeev)
- Fix populate_msi_sysfs() error paths (Greg Kroah-Hartman)
- Fix htmldocs problem (Masanari Iida)
- Add pci_enable_msi_exact() and pci_enable_msix_exact() (Alexander Gordeev)
- Update documentation (Alexander Gordeev)
Miscellaneous:
- mvebu: expose device ID & revision via lspci (Andrew Lunn)
- Enable INTx if the BIOS left them disabled (Bjorn Helgaas)"

Commit 7b92b4f61ec4 ("PCI/MSI: Remove pci_enable_msi_block_auto()")
introduced a regression: if multiple MSI initialization fails, the code
falls back to INTx rather than to single MSI.

Some firmware leaves the Interrupt Disable bit set even if the device uses
INTx interrupts. Clear Interrupt Disable so we get those interrupts.
Based on the report mentioned below, if the user selects the "EHCI only"
option in the Intel Baytrail BIOS, the EHCI device is handed off to the OS
with the PCI_COMMAND_INTX_DISABLE bit set.

The new functions are special cases for pci_enable_msi_range() and
pci_enable_msix_range() when a particular number of MSI or MSI-X
is needed.
By contrast with pci_enable_msi_range() and pci_enable_msix_range()
functions, pci_enable_msi_exact() and pci_enable_msix_exact()
return zero in case of success, which indicates MSI or MSI-X
interrupts have been successfully allocated.

We deprecated pci_enable_msi() in 302a2523c277 ("PCI/MSI: Add
pci_enable_msi_range() and pci_enable_msix_range()").
But we changed our minds after noticing that:
- pci_enable_msi() doesn't have confusing return values like
pci_enable_msi_block() and pci_enable_msix() did, and
- pci_enable_msi() has a hundred or so callers that we don't want to
change.
This adds back the pci_enable_msi() documentation.

Marvell SoCs place the SoC number into the PCIe endpoint device ID. The
SoC stepping is placed into the PCIe revision. The old plat-orion PCIe
driver allowed this information to be seen in user space with a simple
lspci command.
The new driver places a virtual PCI-PCI bridge on top of these endpoints.
It has its own hard coded PCI device ID. Thus it is no longer possible to
see what the SoC is using lspci.
When initializing the PCI-PCI bridge, set its device ID and revision from
the underlying endpoint, thus restoring this functionality. Debian would
like to use this in order to aid installing the correct DTB file.

When an error occurs in the port initialization loop, currently the
driver tries to cleanup all the ports. This results in a NULL pointer
dereference if the ports were only partially initialized.
Fix this by updating only the number of initialized ports (either
with failure or successfully), before jumping to the error path
and looping over that number in the cleanup loop.

It's a bit odd to see a newer device showing mod15write; however, the
reported behavior is highly consistent and other factors which could
contribute seem to have been verified well enough. Also, both
sata_sil itself and the drive are fairly outdated at this point making
the risk of this change fairly low. It is possible, probably likely,
that other drive models in the same family have the same problem;
however, for now, let's just add the specific model which was tested.
