The Bosch MCAN hardware (3.1.0 and above) supports interrupt flag to
detect Protocol error in arbitration phase.
Transmit error statistics is currently not updated from the MCAN driver.
Protocol error in arbitration phase is a TX error and the network
statistics should be updated accordingly.
The member "tx_error" of "struct net_device_stats" should be incremented
as arbitration is a transmit protocol error. Also "arbitration_lost" of
"struct can_device_stats" should be incremented to report arbitration
lost.

According to the CAN Specification (see ISO 11898-1:2015, 8.3.4
Recovery Management), the M_CAN provides means for automatic
retransmission of frames that have lost arbitration or that
have been disturbed by errors during transmission. By default
automatic retransmission is enabled.
The Bosch MCAN controller has support for disabling automatic
retransmission.
To support time-triggered communication as described in ISO
11898-1:2015, chapter 9.2, the automatic retransmission may be
disabled via CCCR.DAR.
CAN_CTRLMODE_ONE_SHOT is used for disabling automatic retransmission.

Userspace can signal with CAN_CTRLMODE_BERR_REPORTING whether they need
reporting of bus errors (CAN_ERR_BUSERROR) or not.
However, xilinx_can driver currently always sends CAN_ERR_BUSERROR
frames to userspace on bus errors.
To improve performance on error conditions when bus error reporting is
not needed, avoid sending CAN_ERR_BUSERROR frames unless requested via
CAN_CTRLMODE_BERR_REPORTING.
The error interrupt is still kept enabled as there is no dedicated state
transition interrupt, but just disabling error frame submission still
yields a significant performance improvement. In a simple test with
continuous bus errors and no userspace programs reading/writing CAN I
saw system CPU load reduced by 1/3.
Tested on a ZynqMP board with CAN-FD v1.0.

Currently, the cpuidle subsystem uses microseconds as the unit of
time which (among other things) causes the idle loop to incur some
integer division overhead for no clear benefit.
In order to allow cpuidle to measure time in nanoseconds, add two
new fields, exit_latency_ns and target_residency_ns, to represent the
exit latency and target residency of an idle state in nanoseconds,
respectively, to struct cpuidle_state and initialize them with the
help of the corresponding values in microseconds provided by drivers.
Additionally, change cpuidle_governor_latency_req() to return the
idle state exit latency constraint in nanoseconds.
Also meeasure idle state residency (last_residency_ns in struct
cpuidle_device and time_ns in struct cpuidle_driver) in nanoseconds
and update the cpuidle core and governors accordingly.
However, the menu governor still computes typical intervals in
microseconds to avoid integer overflows.

Add support for configuring port mirroring through the cls_matchall
classifier. We do a full ingress and/or egress capture towards a
capture port. It allows setting a different capture port for ingress
and egress traffic.
It keeps track of the mirrored ports and the destination ports to
prevent changes to the capture port while other ports are being
mirrored.

The LAN743x Ethernet controller provides two independent PTP event
channels. Each one can be used to generate a periodic output from
the PTP clock. The output can be routed to any one of the available
GPIO pins on the device.
The PTP clock API can now be used to:
- select any LAN743x GPIO pin to function as a periodic output
- select either LAN743x PTP event channel to generate the output
The LAN7430 has 4 GPIO pins that are multiplexed with its internal
PHY LED control signals. A pin assigned to the LED control function
will be assigned to the GPIO function if selected for PTP periodic
output.

The purpose here is to avoid ptp4l fail due to this condition:
timed out while polling for tx timestamp
increasing tx_timestamp_timeout may correct this issue, but it is likely caused by a driver bug
port 1: send peer delay request failed
So either reset the switch before the management frame was sent, or
after it was timestamped as well, but not in the middle.
The condition may arise either due to a true timeout (i.e. because
re-uploading the static config takes time), or due to the TX timestamp
actually getting lost due to reset. For the former we can increase
tx_timestamp_timeout in userspace, for the latter we need this patch.
Locking all traffic during switch reset does not make sense at all,
though. Forcing all CPU-originated traffic to potentially block waiting
for a sleepable context to send > 800 bytes over SPI is not a good idea.
Flows that are autonomously forwarded by the switch will get dropped
anyway during switch reset no matter what. So just let all other
CPU-originated traffic be dropped as well.

The PTP time of the switch is not preserved when uploading a new static
configuration. Work around this hardware oddity by reading its PTP time
before a static config upload, and restoring it afterwards.
Static config changes are expected to occur at runtime even in scenarios
directly related to PTP, i.e. the Time-Aware Scheduler of the switch is
programmed in this way.
Perhaps the larger implication of this patch is that the PTP .gettimex64
and .settime functions need to be exposed to sja1105_main.c, where the
PTP lock needs to be held during this entire process. So their core
implementation needs to move to some common functions which get exposed
in sja1105_ptp.h.

Through the PTP_SYS_OFFSET_EXTENDED ioctl, it is possible for userspace
applications (i.e. phc2sys) to compensate for the delays incurred while
reading the PHC's time.
The task itself of taking the software timestamp is delegated to the SPI
subsystem, through the newly introduced API in struct spi_transfer. The
goal is to cross-timestamp I/O operations on the switch's PTP clock with
values in the local system clock (CLOCK_REALTIME). For that we need to
understand a bit of the hardware internals.
The 'read PTP time' message is a 12 byte structure, first 4 bytes of
which represent the SPI header, and the last 8 bytes represent the
64-bit PTP time. The switch itself starts processing the command
immediately after receiving the last bit of the address, i.e. at the
middle of byte 3 (last byte of header). The PTP time is shadowed to a
buffer register in the switch, and retrieved atomically during the
subsequent SPI frames.
A similar thing goes on for the 'write PTP time' message, although in
that case the switch waits until the 64-bit PTP time becomes fully
available before taking any action. So the byte that needs to be
software-timestamped is byte 11 (last) of the transfer.
The patch creates a common (and local) sja1105_xfer implementation for
the SPI I/O, and offers 3 front-ends:
- sja1105_xfer_u32 and sja1105_xfer_u64: these are capable of optionally
requesting a PTP timestamp
- sja1105_xfer_buf: this is for large transfers (e.g. the static config
buffer) and other misc data, and there is no point in giving
timestamping capabilities to this.

The i2c subsystem was enhanced circa 2015 to support operating as
an i2c-slave device. Prior to that, the i2c-pxa driver supported
an i2c-slave but had its own APIs. There are no existing in-kernel
drivers or platforms that utilize the i2c-pxa APIs.
Migrate the i2c-pxa driver to the general i2c-slave APIs so that
existing drivers, such as the i2c-slave-eeprom, can be used.
This has been tested with a Marvell EspressoBin, using i2c-pxa and
i2c-slave-eeprom, acting as a slave, and a RaspeberryPi 3, using the
at24 driver, acting as a master.

nvme devices report temperature information in the controller information
(for limits) and in the smart log. Currently, the only means to retrieve
this information is the nvme command line interface, which requires
super-user privileges.
At the same time, it would be desirable to be able to use NVMe temperature
information for thermal control.
This patch adds support to read NVMe temperatures from the kernel using the
hwmon API and adds temperature zones for NVMe drives. The thermal subsystem
can use this information to set thermal policies, and userspace can access
it using libsensors and/or the "sensors" command.
Example output from the "sensors" command:
nvme0-pci-0100
Adapter: PCI adapter
Composite: +39.0°C (high = +85.0°C, crit = +85.0°C)

When a jump_whitelist bitmap is reused, it needs to be cleared.
Currently this is done with memset() and the size calculation assumes
bitmaps are made of 32-bit words, not longs. So on 64-bit
architectures, only the first half of the bitmap is cleared.
If some whitelist bits are carried over between successive batches
submitted on the same context, this will presumably allow embedding
the rogue instructions that we're trying to reject.
Use bitmap_zero() instead, which gets the calculation right.
