The Kvaser KCAN controller got a feature to send error frames on request.
The packet KVASER_PCIEFD_PACK_TYPE_EFRAME_ACK signals that the requested
error frame was transmitted.
Since this feature is not supported by the driver, drop the handler and add
KVASER_PCIEFD_PACK_TYPE_EFRAME_ACK to the list of unexpected packet types.

Introduce a method to calculate the exact size in bits of a CAN(-FD)
frame with or without dynamic bitstuffing.
These are all the possible combinations taken into account:
- Classical CAN or CAN-FD
- Standard or Extended frame format
- CAN-FD CRC17 or CRC21
- Include or not intermission
Instead of doing several individual macro definitions, declare the
can_frame_bits() function-like macro. To this extent, do a full
refactoring of the length definitions.
In addition add the can_frame_bytes(). This function-like macro
replaces the existing macro:
- CAN_FRAME_OVERHEAD_SFF: can_frame_bytes(false, false, 0)
- CAN_FRAME_OVERHEAD_EFF: can_frame_bytes(false, true, 0)
- CANFD_FRAME_OVERHEAD_SFF: can_frame_bytes(true, false, 0)
- CANFD_FRAME_OVERHEAD_EFF: can_frame_bytes(true, true, 0)
Function-like macros were chosen over inline functions because they
can be used to initialize const struct fields.
The different maximum frame lengths (maximum data length, including
intermission) are as follow:
Frame type bits bytes
-------------------------------------------------------
Classic CAN SFF no bitstuffing 111 14
Classic CAN EFF no bitstuffing 131 17
Classic CAN SFF bitstuffing 135 17
Classic CAN EFF bitstuffing 160 20
CAN-FD SFF no bitstuffing 579 73
CAN-FD EFF no bitstuffing 598 75
CAN-FD SFF bitstuffing 712 89
CAN-FD EFF bitstuffing 736 92
The macro CAN_FRAME_LEN_MAX and CANFD_FRAME_LEN_MAX are kept as an
alias to, respectively, can_frame_bytes(false, true, CAN_MAX_DLEN) and
can_frame_bytes(true, true, CANFD_MAX_DLEN).
In addition to the above:
- Use ISO 11898-1:2015 definitions for the names of the CAN frame
fields.
- Include linux/bits.h for use of BITS_PER_BYTE.
- Include linux/math.h for use of mult_frac() and
DIV_ROUND_UP(). N.B: the use of DIV_ROUND_UP() is not new to this
patch, but the include was previously omitted.
- Add copyright 2023 for myself.

In their RZN1 SoC, Renesas put a CAN controller supposed to act very
similarly to the original Philips sja1000. In practice, while flooding
the bus with another device, we discovered that the controller very
often after an overrun situation would just refuse any new frame, drop
them all and trigger over and over again the overrun interrupt, even
though the buffer would have been totally emptied. The controller acts
like if its internal buffer offsets (where it writes and where the host
reads) where totally screwed-up.
Renesas manual mentions a single action to perform in order to
resynchronize the read and write offsets within the buffer: performing
a soft reset.
Performing a soft reset takes a bit of time and involves small delays,
so better do that in a threaded handler rather than inside the hard IRQ
handler.
Add platform data to recognize the platforms which need this workaround,
and when the faulty situation is diagnosed, stop what is being
performed and request the threaded handler to be executed in order to
perform the reset.

In order to support a flavor of the sja1000 which sometimes freezes, it
will be needed upon certain interrupts to perform a soft reset. The soft
reset operation takes a bit of time, so better not do it within the hard
interrupt handler but rather in a threaded handler. Let's prepare the
possibility for sja1000_err() to request "interrupting" the current flow
and request the threaded handler to be run while keeping the interrupt
line low.
There is no functional change.

The RK3399 PCIe endpoint controller cannot generate MSI-X IRQs.
This is documented in the RK3399 technical reference manual (TRM)
section 17.5.9 "Interrupt Support".
MSI-X capability should therefore not be advertised. Remove the
MSI-X capability by editing the capability linked-list. The
previous entry is the MSI capability, therefore get the next
entry from the MSI-X capability entry and set it as next entry
for the MSI capability. This in effect removes MSI-X from the list.

The RK3399 PCI endpoint core has 33 windows for PCIe space, now in the
driver up to 32 fixed size (1M) windows are used and pages are allocated
and mapped accordingly. The driver first used a single window and allocated
space inside which caused translation issues (between CPU space and PCI
space) because a window can only have a single translation at a given
time, which if multiple pages are allocated inside will cause conflicts.
Now each window is a single region of 1M which will always guarantee that
the translation is not in conflict.
Set the translation register addresses for physical function. As documented
in the technical reference manual (TRM) section 17.5.5 "PCIe Address
Translation" and section 17.6.8 "Address Translation Registers Description"

From the git history, I can see that all the __packed annotations were done
specifically to avoid introducing implicit padding around the lpfc_name
instances, though this was probably the wrong approach.
To improve this, only annotate the one uint64_t field inside of lpfc_name
as packed, with an explicit 4-byte alignment, as is the default already on
the 32-bit x86 ABI but not on most others. With this, the other __packed
annotations can be removed again, as this avoids the incorrect padding.
Two other structures change their layout as a result of this change:
- struct _LOGO never gained a __packed annotation even though it has the
same alignment problem as the others but is not used anywhere in the
driver today.
- struct serv_param similarly has this issue, and it is used, my guess is
that this is only an internal structure rather than part of a binary

Add additional modes for specific link duplex. Use ethtool APIs to get the
current link duplex and enable the LED accordingly. Under netdev event
handler the rtnl lock is already held and is not needed to be set to
access ethtool APIs.
This is especially useful for PHY and Switch that supports LEDs hw
control for specific link duplex.
Add additional modes:
- half_duplex: Turn on LED when link is half duplex
- full_duplex: Turn on LED when link is full duplex

current link speed and enable the LED accordingly. Under netdev event
handler the rtnl lock is already held and is not needed to be set to
access ethtool APIs.
This is especially useful for PHY and Switch that supports LEDs hw
control for specific link speed. (example scenario a PHY that have 2 LED
connected one green and one orange where the green is turned on with
1000mbps speed and orange is turned on with 10mpbs speed)
On mode set from sysfs we check if we have enabled split link speed mode
and reject enabling generic link mode to prevent wrong and redundant
configuration.
Rework logic on the set baseline state to support these new modes to
select if we need to turn on or off the LED.
Add additional modes:
- link_10: Turn on LED when link speed is 10mbps
- link_100: Turn on LED when link speed is 100mbps
- link_1000: Turn on LED when link speed is 1000mbps

Qualcomm driver updates for v6.5
Konrad Dybcio is promoted, from reviewer, to co-maintainer.
The mdt_loader gets a fix to the detection of split binaries, where the
previous logic sometimes concluded that the first segments was not
split, in a split image. The unconditional calling of
scm_pas_mem_setup() turns out to cause a regression and is reverted.
The altmode subfunction of pmic_glink is enabled for SM8450.
A new driver for exposing power statistics from the RPM, for debugging
purposes, is introduced.
OCMEM gets a debug prints of the hardware version, QMI helpers are
transitioned to alloc_ordered_workqueue() and an error message in
ramp_controller is improved.
An API is introduced to the SMEM driver to allow other drivers to query
the SoC id, rather than open-coding the parsing of the relevant SMEM
item. This is then used to clean up the Qualcomm NVMEM-based cpufreq
driver.
Socinfo is extended with knowledge about IPQ5018, IPQ5312 and IPQ5302.

interconnect changes for 6.5
This pull request contains the interconnect changes for the 6.5-rc1 merge
window which is a mix of core and driver changes with the following highlights:
- Support for configuring QoS on the Qualcomm's RPM-based platforms, that
required special handling of some interface (non-scaling) clocks.
- Support for clock-based interconnect providers for cases when clock
corresponds to bus bandwidth. This is used to enable CPU cluster bandwidth
scaling on MSM8996 platforms. One patch is touching a file in the clock
subsystem that has been acked by the maintainer.
Core changes:
interconnect: add clk-based icc provider support
interconnect: icc-clk: fix modular build
interconnect: drop unused icc_get() interface
Driver changes:
interconnect: qcom: rpm: Rename icc desc clocks to bus_blocks

interconnect: qcom: rpm: Drop unused parameters
interconnect: qcom: rpm: Set QoS registers only once
