rtw88: 8723d: Add power tracking
When chip's temperature is changed, RF characters are changed. To keep the
characters to be consistent, 8723d uses thermal meter to assist in
calibrating LCK, IQK, crystal and TX power.
A base thermal value is programmed in efuse, all calibration data in
MP process is based on this thermal value. So we calucate the delta of
thermal value between the base value, and use this delta to reference XTAL
and TX power offset tables to know how much we need to adjust.
For IQK and LCK, driver checks if delta of thermal value is over 8, then
they are triggered.
For crystal adjustment, when delta of thermal value is changed, we check
XTAL tables to get offset of XTAL value. If thermal value is larger than
base value, positive table (_p as suffix) is used. Otherwise, we use
negative table (_n as suffix). Then, we add offset to XTAL default value
programmed in efuse, and write sum value to register.
To compensate TX power, there are two hierarchical tables. First level use
delta of thermal value to access eight tables to yield delta of TX power
index. Then, plus base TX power index to get index of BB swing table
(second level tables) where register value is induced.
BB swing table can't deal with all cases, if index of BB swing table is
over the size of the table. In this case, TX AGC is used to compensate the
remnant part. Assume 'upper' is the upper bound of BB swing table, and
'target' is the desired index. Then, we can illustrate them as
compensation method BB swing TX AGC
------------------- -------- --------------
target > upper upper target - upper
target < 0 0 target
otherwise target 0

rtw88: 8723d: add IQ calibration
IQ calibration is used to calibrate RF characteristic to yield expected
performance. Basically, we do calibration twice and compare the similarity
to determine calibration is good or not, if not we do the third
calibration, and then compare with the results of first and second
calibration. If it still not similar, IQK is failed.
Before doing calibration, we need to backup registers that will be
modified in calibration procedure, and restore these registers after
calibration is done.
A calibration procedure can divided into four sub-procedures that are
S1-TX, S1-RX, S0-TX and S0-RX. Where, S1 and S0 represent to path A and B
respectively. Each sub-procedure configure proper registers, and then
rigger one-shot calibration and poll until completion. For RX calibration,
it needs to do twice one-shot calibration, first one is to yield parameter
used by second one.
The result of TX part is stored for TX power tracking that adjusts TX AGC
to output expected power.

rndis_wlan: Replace zero-length array with flexible-array
The current codebase makes use of the zero-length array language

variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

When plumbing rxiv for (GTK) keys, current code does not use seq/seq_len
when present nor set iv_initialized for iovar wsec_key. This could
result in missing broadcast traffic after GTK rekey. The fix is setting
iv_initialized and using seq/seq_len for iovar wsec_key.

The driver sends an action frame down and waits for dwell time to be

Driver issues "scan abort" to cancel the current time slot, but this

In this change, priority is adjusted based on the AP WMM params

net: dsa: sja1105: implement tc-gate using time-triggered virtual links
Restrict the TTEthernet hardware support on this switch to operate as
closely as possible to IEEE 802.1Qci as possible. This means that it can
perform PTP-time-based ingress admission control on streams identified
by {DMAC, VID, PCP}, which is useful when trying to ensure the
determinism of traffic scheduled via IEEE 802.1Qbv.
The oddity comes from the fact that in hardware (and in TTEthernet at
large), virtual links always need a full-blown action, including not
only the type of policing, but also the list of destination ports. So in
practice, a single tc-gate action will result in all packets getting
dropped. Additional actions (either "trap" or "redirect") need to be
specified in the same filter rule such that the conforming packets are
actually forwarded somewhere.
Apart from the VL Lookup, Policing and Forwarding tables which need to
be programmed for each flow (virtual link), the Schedule engine also
needs to be told to open/close the admission gates for each individual
virtual link. A fairly accurate (and detailed) description of how that
works is already present in sja1105_tas.c, since it is already used to
trigger the egress gates for the tc-taprio offload (IEEE 802.1Qbv). Key
point here, we remember that the schedule engine supports 8
"subschedules" (execution threads that iterate through the global
schedule in parallel, and that no 2 hardware threads must execute a
schedule entry at the same time). For tc-taprio, each egress port used
one of these 8 subschedules, leaving a total of 4 subschedules unused.
In principle we could have allocated 1 subschedule for the tc-gate
offload of each ingress port, but actually the schedules of all virtual
links installed on each ingress port would have needed to be merged
together, before they could have been programmed to hardware. So
simplify our life and just merge the entire tc-gate configuration, for
all virtual links on all ingress ports, into a single subschedule. Be
sure to check that against the usual hardware scheduling conflicts, and
program it to hardware alongside any tc-taprio subschedule that may be
present.

Under the hood, all rules match on DMAC, VID and PCP, but when VLAN
filtering is disabled, those are set internally by the driver to the

deny changing vlan_filtering unless the list of flows offloaded via

net: dsa: introduce a dsa_port_from_netdev public helper
As its implementation shows, this is synonimous with calling
dsa_slave_dev_check followed by dsa_slave_to_port, so it is quite simple
already and provides functionality which is already there.
However there is now a need for these functions outside dsa_priv.h, for
example in drivers that perform mirroring and redirection through
tc-flower offloads (they are given raw access to the flow_cls_offload
structure), where they need to call this function on act->dev.
But simply exporting dsa_slave_to_port would make it non-inline and
would result in an extra function call in the hotpath, as can be seen
for example in sja1105:
Before:

u16 tx_vid = dsa_8021q_tx_vid(dp->ds, dp->index);
6fc:
e1a08000 mov r8, r0
After:
000006e4 <sja1105_xmit>:
{
6e4:
e92d4ff0 push {r4, r5, r6, r7, r8, r9, sl, fp, lr}

{
6f4:
e1a05001 mov r5, r1
struct dsa_port *dp = dsa_slave_to_port(netdev);
6f8:

Because we want to avoid possible performance regressions, introduce
this new function which is designed to be public.

First set of patches for v5.8. Changes all over, ath10k apparently
seeing most new features this time. rtw88 also had lots of changes due
to preparation for new hardware support.
In this pull request there's also a new macro to include/linux/iopoll:
read_poll_timeout_atomic(). This is needed by rtw88 for atomic
polling.
Major changes:
ath11k
* add debugfs file for testing ADDBA and DELBA
* add 802.11 encapsulation offload on hardware support
* add htt_peer_stats_reset debugfs file
ath10k

====================
Add QRTR MHI client driver
Here is the series adding MHI client driver support to Qualcomm IPC router
protocol. MHI is a newly added bus to kernel which is used to communicate to
external modems over a physical interface like PCI-E. This driver is used to
transfer the QMI messages between the host processor and external modems over
the "IPCR" channel.
For QRTR, this driver is just another driver acting as a transport layer like
SMD.
Currently this driver is needed to control the QCA6390 WLAN device from ath11k.
The ath11k MHI controller driver will take care of booting up QCA6390 and
bringing it to operating state. Later, this driver will be used to transfer QMI
messages over the MHI-IPCR channel.
The second patch of this series removes the ARCH_QCOM dependency for QRTR. This
is needed because the QRTR driver will be used with x86 machines as well to talk
to devices like QCA6390.

net: qrtr: Do not depend on ARCH_QCOM
IPC Router protocol is also used by external modems for exchanging the QMI
messages. Hence, it doesn't always depend on Qualcomm platforms. One such
instance is the QCA6390 WLAN device connected to x86 machine.
