Add three macro to simplify the readability of big bit timing numbers:
- CAN_KBPS: kilobits per second (one thousand)
- CAN_MBPS: megabits per second (one million)
- CAN_MHZ: megahertz per second (one million)
Example:
u32 bitrate_max = 8 * CAN_MBPS;
struct can_clock clock = {.freq = 80 * CAN_MHZ};
instead of:
u32 bitrate_max = 8000000;
struct can_clock clock = {.freq = 80000000};
Apply the new macro to driver/net/can/dev/bittiming.c.

The logic for the tdco calculation is to just reuse the normal sample
point: tdco = sp. Because the sample point is expressed in tenth of
percent and the tdco is expressed in time quanta, a conversion is
needed.
At the end,
ssp = tdcv + tdco
= tdcv + sp.
Another popular method is to set tdco to the middle of the bit:
tdc->tdco = can_bit_time(dbt) / 2
During benchmark tests, we could not find a clear advantages for one
of the two methods.
The tdco calculation is triggered each time the data_bittiming is
changed so that users relying on automated calculation can use the
netlink interface the exact same way without need of new parameters.
For example, a command such as:
ip link set canX type can bitrate 500000 dbitrate 4000000 fd on
would trigger the calculation.
The user using CONFIG_CAN_CALC_BITTIMING who does not want automated
calculation needs to manually set tdco to zero.
For example with:
ip link set canX type can tdco 0 bitrate 500000 dbitrate 4000000 fd on
(if the tdco parameter is provided in a previous command, it will be
overwritten).
If tdcv is set to zero (default), it is automatically calculated by
the transiver for each frame. As such, there is no code in the kernel
to calculate it.
tdcf has no automated calculation functions because we could not
figure out a formula for this parameter.

In order to implement byte queue limits (bql) in CAN drivers, the
length of the CAN frame needs to be passed into the networking stack
even if the transmission failed for some reason.
To avoid to calculate this length twice, extend can_free_echo_skb() to
return that value. Convert all users of this function, too.
This patch is the natural extension of commit:
| 9420e1d495e2 ("can: dev: can_get_echo_skb(): extend to return can

We sometimes see COMMAND_IGNORED responses during the clock stop
sequence. It turns out we already have information if devices are
present on a link, so we should only prepare those when they
are attached.
In addition, even when COMMAND_IGNORED are received, we should still
proceed with the clock stop. The device will not be prepared but
that's not a problem.
The only case where the clock stop will fail is if the Cadence IP
reports an error (including a timeout), or if the devices throw a
COMMAND_FAILED response.

The existing code makes no sense, we multiply a channel number by
zero (SDW_BLK_GRP_CNT_1), and the result is used to configure the
block packing mode. Sampling grouping and channel packing are two
separate concepts in SoundWire.
In addition, the bandwidth allocation allocates a vertical slice for
each stream, which makes the use of the PER_CHANNEL packing mode
irrelevant.
Let's use the proper definition for block packing mode (PER_PORT).
This change has no functional impact though since the net result is
the same configuration of the DPN_BlockCtrl3 register, when
implemented.

When Secure World returns, it may have changed the size attribute of the
memory references passed as [in/out] parameters. The GlobalPlatform TEE
Internal Core API specification does not restrict the values that this
size can take. In particular, Secure World may increase the value to be
larger than the size of the input buffer to indicate that it needs more.
Therefore, the size check in optee_from_msg_param() is incorrect and
needs to be removed. This fixes a number of failed test cases in the
GlobalPlatform TEE Initial Configuratiom Test Suite v2_0_0_0-2017_06_09
when OP-TEE is compiled without dynamic shared memory support
(CFG_CORE_DYN_SHM=n).

As clk_core_populate_parent_map() checks clk_init_data.num_parents
first, and checks clk_init_data.parent_names[] before
clk_init_data.parent_data[] and clk_init_data.parent_hws[], leaving the
latter uninitialized doesn't do harm for now. However, it is better to
play it safe, and initialize all clk_init_data structures to zeroes, to
avoid any current and future members containing uninitialized data.
Remove a few explicit zero initializers, which are now superfluous.

So far the creation of the TX echo skb was optional and can be
controlled by the local sender of a CAN frame.
It turns out that the TX echo CAN skb can be piggybacked to carry
information in the driver from the TX- to the TX-complete handler.
Several drivers already use the return value of
can_get_echo_skb() (which is the length of the data field in the CAN
frame) for their number of transferred bytes statistics. The
statistics are not working if CAN echo skbs are disabled.
Another use case is to calculate and set the CAN frame length on the
wire, which is needed for BQL support in both the TX and TX-completion
handler.
For now in can_put_echo_skb(), which is called from the TX handler,
the skb carrying the CAN frame is discarded if no TX echo is
requested, leading to the above illustrated problems.
This patch changes the can_put_echo_skb() function, so that the echo
skb is always generated. If the sender requests no echo, the echo skb
is consumed in __can_get_echo_skb() without being passed into the RX
handler of the networking stack, but the CAN data length and CAN frame
length information is properly returned.

Add support for the legacy keyboard (KBD/TC=0x08) HID transport layer of
the Surface System Aggregator Module (SSAM) to the Surface HID driver.
On Surface Laptops 1 and 2, this interface is used to connect the
integrated keyboard.
Note that this subsystem interface essentially provides a limited HID
transport layer. In contrast to the generic HID interface (TC=0x15) used
on newer Surface models, this interface only allows (as far as we know)
for a single device to be connected and is otherwise severely limited in
terms of support for feature- and output-reports. Specifically, only
caps-lock-LED output-reports and a single read-only feature-report are
supported.

Add a HID transport driver to support integrated HID devices on newer
Microsoft Surface models (specifically 7th-generation, i.e. Surface
Laptop 3, Surface Book 3, and later).
On those models, the internal keyboard and touchpad (as well as some
other HID devices with currently unknown function) are connected via the
generic HID subsystem (TC=0x15) of the Surface System Aggregator Module
(SSAM). This subsystem provides a generic HID transport layer, support
for which is implemented by this driver.

instead set sdw_driver.driver.name.
This leads to error messages such as
[ 23.935355] rt700 sdw:2:25d:700:0: Probe of (null) failed: -19
We could remove this sdw_driver.name if it doesn't have any
purpose. This patch only suggests using the proper indirection.

Remove restriction blocking configuration of CQE compression when PTP rx
filter is set. Instead turn on indication for RX PTP, and try to reopen
the channels.

Update setting HW time-stamp to allow coexistence with CQE compression.
Turn on RX PTP indication and try to reopen the channels. On success,
coexistence with CQE compression is enabled. Otherwise, fall-back to
turning off CQE compression.

When opening PTP channel with MLX5E_PTP_STATE_RX set, add the
corresponding flow steering rules. Capture UDP packets with destination
port 319 and L2 packets with ethertype 0x88F7 and steer them into the RQ
of the PTP channel.
Add API that manages the flow steering rules to be used in the following
patches via safe_reopen_channels mechanism.

Add a new FS API which captures the ANY traffic from the traffic
classifier into a dedicated FS table. The table consists of a group
matching the ethertype and a must-be-last group which contains a default
rule redirecting the unmatched packets back to the RSS logic.

Add a new FS API which captures the UDP traffic from the traffic
classifier into a dedicated FS table. This API handles both UDP over
IPv4 and IPv6 in the same manner. The tables (one for UDPv4 and another
for UDPv6) consist of a group matching the UDP destination port and a
must-be-last group which contains a default rule redirecting the
unmatched packets back to the RSS logic.

Flow Steering levels are used to determine the order between the tables.
As of today, each one of these tables follows the TTC table, and hijacks
its traffic, and cannot be combined together for now. Putting them in
the same layer better reflects the situation.

Enhance PTP channel to allow PTP without disabling CQE compression. Add
RQ, TIR and PTP_RX_STATE to PTP channel. When this bit is set, PTP
channel manages its RQ, and PTP traffic is directed to the PTP-RQ which
is not affected by compression.

The PTP channel state will be used for separation and coexistence of RX
