This patch introduces the crypto skcipher interface which aims
to replace both blkcipher and ablkcipher.
It's very similar to the existing ablkcipher interface. The
main difference is the removal of the givcrypt interface. In
order to make the transition easier for blkcipher users, there
is a helper SKCIPHER_REQUEST_ON_STACK which can be used to place
a request on the stack for synchronous transforms.

Add a pci_scan_root_bus_msi() interface so an arch can specify the MSI
controller up front. This removes the need for a pcibios callback to set
the MSI controller later.
This is not exported because I'd like to replace the variety of "scan root
bus" interfaces with a single, more extensible interface that can handle
the MSI controller, domain, pci_ops, resources, etc. I hope this interface
is temporary.

ASoC: Disable topology support for v4.2
The topology code merged in the v4.2 merge window introduced a new ABI
which was believed to be suitable for use but subsequently additional
work by the developers of this feature have revealed some problems that
need to be addressed. In order to allow this to be done without having
to support the initial ABI add Kconfig to disable the build and also add
some #error statements to the UAPI header so users can't use them.

Voltage tolerance isn't necessarily same on both sides of the target
voltage and regulator_set_voltage_tol() wouldn't be suitable in such
cases.
Add another routine regulator_set_voltage_triplet(), which accepts
target, min and max voltages as arguments.
This first tries to set the voltage between the target voltage and the
upper limit, then fall back on the full range. The idea behind this is
to set regulator's voltage as close to the target voltage, as possible.
Based on regulator_set_voltage_tol().

TAR 9000378958
Title: Non-Double Word Aligned Buffer Address Sometimes Causes Host to
Hang on OUT Retry
Impacted Configuration: Host mode, all transfer types
Description:
The host core operating in streaming mode may under run while sending
the data packet of an OUT transaction. This under run can occur if
there are unexpected system delays in fetching the remaining packet
data from memory. The host forces a bad CRC on the packet, the device
detects the error and discards the packet. The host then retries a Bulk,
Interrupt, or Control transfer if an under run occurs according to the
USB specification. During simulations, it was found that the host does
not issue the retry of the failed bulk OUT. It does not issue any other
transactions except SOF packets that have incorrect frame numbers.
The second failure mode occurs if the under run occurs on an ISO OUT
transaction and the next ISO transaction is a zero byte packet. The host
does not issue any transactions (including SOFs). The device detects a
Suspend condition, reverts to full speed, and waits for resume signaling.
A third failure mode occurs when the host under runs on an ISO OUT and
the next ISO in the schedule is an ISO OUT with two max packets of 1024
bytes each. The host should issue MDATA for the first OUT followed by
DATA1 for the second. However, it drops the MDATA transaction, and
issues the DATA1 transaction.
The system impact of this bug is the same regardless of the failure mode
observed. The host core hangs, the ehci_ctrl state machine waits for the
protocol engine to send the completion status for the corrupted
transaction, which never occurs. No indication is sent to the host
controller driver, no register bits change and no interrupts occur.
Eventually the requesting application times out.
Detailed internal behavior:
The EHCI control state machine (ehci_ctrl) in the DMA block is responsible
for parsing the schedules and initiating all transactions. The ehci_ctrl
state machine passes the transaction details to the protocol block by
writing the transaction information in to the TxFIFO. It then asserts
the pe_hst_run_pkt signal to inform the host protocol state machine
(pe_hst_state) that there is a packet in the TxFIFO.
A tag of 0x0 indicates a start of packet with the data providing the
following information:
35:32 Tag
31:30 Reserved
29:23 Endpoint (lowest 4 bits)
22:16 Address
15:10 Reserved
9:8 Endpoint speed
7:6 Endpoint type
5:6 Data Toggle
3:0 PID
The pe_hst_state reads the packet information and constructs the packet
and issues it to the PHY interface.
The ehci_ctrl state machine writes the start transaction information in
to the TxFIFO as 0x03002910c for the OUT packet that had the under run
error. However, it writes 0xC3002910C for the retry of the Out
transaction, which is incorrect.
The pe_hst_state enters a bus timeout state after sending the bad CRC
for the packet that under ran. It then purges any data that was back
filled in to the TxFIFO for the packet that under ran. The pe_hst_state
machine stops purging the TxFIFO when it is empty or if it reads a
location that has a tag of 0x0, indicating a start of packet command.
The pe_hst_state reads 0xC3002910C and discards it as it does not decode
to a start of packet command. It continues to purge the OUT data that
has been pre-buffered for the OUT retry . The pe_hst_state detects the
hst_packet_run signal and attempts to read the PID and address
information from the TxFIFO. This location has packet data and so does
not decode to a valid PID and so falls through to the PE_HST_SOF_LOAD
state where the frame_num_counter is updated. The frame_num_counter
is updated with the data in the TxFIFO. In this case, the data is
incorrect as the ehci_ctrl state machine did not initiate the load.
The hst_pe_state machine detects the SOF request signal and sends an
SOF with the bad frame number. Meanwhile, the ehci_ctrl state machine
waits indefinitely in the run_pkt state waiting for the completion
status from pe_hst_state machine, which will never happen.
The ISO failure case is similar except that there is no retry for ISO.
The ehci_ctrl state machine moves to the next transfer in the periodic
schedule. If the under run occurs on the last entry of the periodic
list then it moves to the Async schedule.
In the case of ISO OUT simulations, the next ISO is a zero byte OUT
and again the start of packet command gets corrupted. The TxFIFO is
empty when the hst_pe_state attempts to read the Address and PID
information as the transaction is a zero byte packet. This results
in the hst_pe_state machine staying in the GET_PID state, which means
that it does not issue any transactions (including SOFs). The device
detects a Suspend condition and reverts to full speed mode and waits
for a Resume or Reset signal.
The EHCI specification allows a Non-DoubleWord (32 bits) offset to
be used as a current offset for Buffer Pointer Page 0 of the qTD.
In Non-DoubleWord aligned cases, the core reads the packet data
from the AHB memory, performs the alignment operation before writing
it in to the TxFIFO as a 32 bit data word. An End Of Packet tag (EOP)
is written to the TxFIFO after all the packet data has been written
in to the TxFIFO. The alignment function is reset to Idle by the EOP
tag. The corruption of the start of packet command arises because the
packet buffer for the OUT transaction that under ran is not aligned
to a DoubleWord, and hence no EOP tag is written to the TxFIFO. The
alignment function is still active when the start packet information
is written in to the TxFIFO for the retry of the bulk packet or for
the next transaction in the case of an under run on an ISO. This
results in the corruption of the start tag and the transaction
information.
Click for waveform showing the command 0x 0000300291 being written in
to the TX FIFO for the Out that under ran.
Click for waveform showing the command 0xC3002910C written to the
TxFIFO instead of 0x 0000300291
Versions affected: Versions 2.10a and previous versions
How discovered: Customer simulation
Workaround:
1- The EHCI specification allows a non-DoubleWord offset to be used
as a current offset for Buffer Pointer Page 0 of the qTD. However,
if a DoubleWord offset is used then this issue does not arise.
2- Use non streaming mode to eliminate under runs.
Resolution:
The fix involves changes to the traffic state machine in the
vusb_hs_dma_traf block. The ehci_ctrl state machine updates the context
information by encoding the transaction results on the
hst_op_context_update signals at the end of a transaction. The signal
hst_op_context_update is added to the traffic state machine, and the
tx_fifo_under_ran_r signal is generated if the transaction results in
an under run error. Click for waveform
The traffic state machine then traverses to the do_eop states if the
tx_fifo_under_ran error is asserted. Thus an EOP tag is written in to
the TxFIFO as shown in this waveform .
The EOP tag resets the align state machine to the Idle state ensuring
that the next command written by the echi_ctrl state machine does not
get corrupted.

ITC (Interrupt Threshold Control) is used to set the maximum rate at which
the host/device controller will issue interrupts. The default value is 8 (1ms)
for it. EHCI core will modify it to 1, but device mode keeps it as default
value.
In some use cases like Android ADB, it only has one usb request for each
direction, and maximum payload data is only 4KB, so the speed is 4MB/s
at most, it needs controller to trigger interrupt as fast as possible
to increase the speed. The USB performance will be better if the interrupt
can be triggered faster.
Reduce ITC value is benefit for USB performance, but the interrupt number
is increased at the same time, it may increase cpu utilization too.
Most of use case cares about performance, but some may care about
cpu utilization, so, we leave a platform interface for user.
We set ITC as 1 (1 micro-frame) as default value which is aligned
with ehci core default value.

The register of ttctrl.ttha describes like below:
- Internal TT Hub Address Representation
- RW
- Default = 0000000b
This field is used to match against the Hub Address field in QH & siTD
to determine if the packet is routed to the internal TT for directly
attached FS/LS devices. If the Hub Address in the QH or siTD does not
match this address then the packet will be broadcast on the High Speed
ports destined for a downstream High Speed hub with the address in the QH/siTD.
In silicon RTL, this entry only affects QH and siTD, and the hub.addr at
both QH and siTD are 0 in ehci core for chipidea (with hcd->has_tt = 1).
So, for QH, if the "usage_tt" flag at RTL is 0, set CI_HDRC_SET_NON_ZERO_TTHA
will not affect QH (with non-hs device); for siTD, set this flag
will change remaining space requirement for the last transaction from 1023
bytes to 188 bytes, it can increase the number of transactions within one
frame, ehci periodic schedule code will not queue the packet if the frame space
is full, so it is safe to set this flag for siTD.
With this flag, it can fix the problem Alan Stern reported below:

Remove pci_ats_enabled(). There are no callers outside the ATS code
itself. We don't need to check ats_cap, because if we don't find an ATS
capability, we'll never set ats_enabled.

Stop caching the Invalidate Queue Depth in struct pci_dev.
pci_ats_queue_depth() is typically called only once per device, and it
returns a fixed value per-device, so callers who need the value frequently
can cache it themselves.

The extended capabilities list is linked with 12-bit pointers, and the ATS
Smallest Translation Unit and Invalidate Queue Depth fields are both 5
bits.
Use u16 and u8 to hold the extended capability address and the stu and qdep
values. No functional change.

The pci_ats struct is small and will get smaller, so I don't think it's
worth allocating it separately from the pci_dev struct.
Embed the ATS fields directly into struct pci_dev.

Previously, we allocated pci_ats structures when an IOMMU driver called
pci_enable_ats(). An SR-IOV VF shares the STU setting with its PF, so when
enabling ATS on the VF, we allocated a pci_ats struct for the PF if it
didn't already have one. We held the sriov->lock to serialize threads
concurrently enabling ATS on several VFS so only one would allocate the PF
pci_ats.
Gregor reported a deadlock here:
pci_enable_sriov
sriov_enable
virtfn_add
mutex_lock(dev->sriov->lock) # acquire sriov->lock
pci_device_add
device_add
BUS_NOTIFY_ADD_DEVICE notifier chain
iommu_bus_notifier
amd_iommu_add_device # iommu_ops.add_device
init_iommu_group
iommu_group_get_for_dev
iommu_group_add_device
__iommu_attach_device
amd_iommu_attach_device # iommu_ops.attach_device
attach_device
pci_enable_ats
mutex_lock(dev->sriov->lock) # deadlock
There's no reason to delay allocating the pci_ats struct, and if we
allocate it for each device at enumeration-time, there's no need for
locking in pci_enable_ats().
Allocate pci_ats struct during enumeration, when we initialize other
capabilities.
Note that this implementation requires ATS to be enabled on the PF first,
before on any of the VFs because the PF controls the STU for all the VFs.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
Second set of new device support, features and cleanup for the 4.3 cycle.
Take 2 also includes a fix set that was too late for the 4.2 cycle.
As we had a lot of tools and docs work in this set, I have broken those
out into their own categories in this description.
Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'.
* Poll functions for both event chardev and the buffer one were returning
negative error codes (via a positive value).
* A recent change to lsiio adding some error handling that was wrong and
stopped the tool working.
* bmg160 was missing some dependencies in Kconfig
* berlin2-adc had a misshandled register (wrote a value rather than a bitmap)
New device support
* TI opt3001 light sensor
* TXC PA12 ALS and proximity sensor.
* mcp3301 ADC support (in mcp320x driver)
* ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors
common support to allow different WHOAMI register addresses, devices with
fixed scale and allow interrupt equiped magnetometers).
* ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver)
* ADIS16266 gyro (in the adis16260 driver)
* ADIS16137 gyro (in the adis16136 driver)
New functionality
* mmc35240 DT bindings.
* Inverse unit conversion macros to aid handing of values written to sysfs
attributes.
Core cleanup
* Forward declaration of struct iio_trigger to avoid a compile warning.
Driver cleanup / fixes
* mxs-lradc
- Clarify which parts are supported.
- Fix spelling erorrs.
- Missing/extra includes
- reorder includes
- add datasheet name listings for all usable channels (to allow them
to be bound by name from consumer drivers)
* acpi-als - add some function prefixes as per general iio style.
* bmc150_magn - replace a magic value with the existing define.
* vf610 - determine possible sample frequencies taking into account the
electrical characteristics (defining a minimum sample time)
* dht11
- whitespace
- additional docs
- avoid mulitple assignments in one line
- Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick
previously used for timing.
* Fix all drivers that consider 0 a valid IRQ for historical reasons.
* Export I2C module alias info where previously missing (to allow autoprobing)
* Export OF module alias info where previously missing.
* mmc35240 - switch some variables into arrays to improve readability.
* mlx90614 - define some magic numbers for readability.
* bmc150_magn
- expand area locked by a mutex to cover all the use of the
data->buffer.
- use descriptive naming for a mask instead of a magic value.
* berin2-adc
- pass up an error code rather that a generic error
- constify the iio_chan_spec
- some other little tidy ups.
* stk8312
- fix a dependency on triggered buffers in kconfig
- add a check for invalid attribute values
- improve error handling by returning error codes where possible and
return immediately where relevant
- rework macro defs to use GENMASK etc
- change some variable types to reduce unnecessary casting
- clean up code style
- drop a local buffer copy for bulk reads and use the one in data->buffer
instead.
* adis16400 - the adis16448 gyroscope scale was wrong.
* adis16480 - some more wrong scales for various parts.
* adis16300 - has an undocumented product id and serial number registers so
use them.
* iio_simple_dummy - fix some wrong code indentation.
* bmc150-accel - use the chip ID to detect the chip present rather than
verifying the expected part was there. This was in response to a wrong
ACPI entry on the WinBook TW100.
* mma8452
- fix _get_hp_filter_index
- drop a double include
- pass up an error code rather than rewriting it
- range check input values to attribute writes
- register defs tidy up using GENMASK and reordering them to be easier to
follow.
- various coding style cleanups
- put the Kconfig entry in the write place (alphabetically).
Tools related
* Tools cleanup - drop an explicity NULL comparison, some unnecessary braces,
use the ARRAY_SIZE macro, send error messages to stderr instead of dropping
them in the middle of normal output.
* Fix tools to allow that scale and offset attributes are optional.
* More tools fixes including allowing true 32bit data (previously an overflow
prevented more than 31bits)
* Drop a stray header guard that ended up in a c file.
* Make calc_digits static as it isn't exported or in the header.
* Set ci_array pointer to NULL after free as a protection against non safe
usage of the tools core code. Also convert a double pointer to a single
one as the extra level of indirection was unnecessary.
Docs
* DocBook introduction by Daniel Baluta. Glad we are beginning to
draw together some more introductory docs to suplement the various
tools / examples.
* Drop bytes_per_datum sysfs attribute docs as it no longer exists.
* A whole load of missing / fixing of kernel-doc for the core of IIO.
* Document the trigger name sysfs attribute in the ABI docs.
* Minor typos in the ABI docs related to power down modes.
