The D3 handshake can be interrupted by an error, especially
on resume where we no longer want to check explicitly for
errors. Expand the sx_complete to sx_state and handle any
errors occurring during the handshake.

At load time, the firmware may request a TOP reset via
bit 6 in the IPC status register. Handle that and set
TOP reset in that case. Since the init will be retried,
there's no need to do anything else.

This patch set adds all the supported FLEXCOMs for the SAMA7D65 SoC.
This also adds the GMAC interfaces and enables GMAC0 interface for
the SAMA7D65 SoC.
With the FLEXCOMs added to the SoC the MCP16502 and the MAC address
EEPROM are both added to flexcom10.
The dt-binding for USART is here [1]. And the dt-binding for DMA has
been applied here [2].
The original thread for this is here [3]. The applied changes have been
removed for this resend

This patch avoids another update of the consumer at the end of
dpaa2_xsk_tx().
In the zero copy xmit path, two versions (batched and non-batched)
regarding how the consumer of tx ring changes are implemented in
xsk_tx_peek_release_desc_batch() that eventually updates the local
consumer to the global consumer in either of the following call trace:
1) batched mode:
xsk_tx_peek_release_desc_batch()
__xskq_cons_release()
2) non-batched mode:
xsk_tx_peek_release_desc_batch()
xsk_tx_peek_release_fallback()
xsk_tx_release()
As we can see, dpaa2_xsk_tx() doesn't need to call extra release function
to handle the sync of consumer itself.

NL80211_ATTR_WIPHY_RADIOS. When a request for getting RTS threshold
for a particular radio is received, parse the radio id and get the

Currently, setting RTS threshold is based on per-phy basis, i.e., all the
radios present in a wiphy will take RTS threshold value to be the one sent
from userspace. But each radio in a multi-radio wiphy can have different
RTS threshold requirements.
To extend support to set RTS threshold for each radio, get the radio for
which RTS threshold needs to be changed from the user. Use the attribute
in NL - NL80211_ATTR_WIPHY_RADIO_INDEX, to identify the radio of interest.
Create a new structure - wiphy_radio_cfg and add rts_threshold in it as a
u32 value to store RTS threshold of each radio in a wiphy and allocate
memory for it during wiphy register based on the wiphy.n_radio updated by
drivers. Pass radio id received from the user to mac80211 drivers along
with its corresponding RTS threshold.

Currently, per-radio attributes are set on per-phy basis, i.e., all the
radios present in a wiphy will take attributes values sent from user. But
each radio in a wiphy can get different values from userspace based on
its requirement.
To extend support to set per-radio attributes, add support to get radio
index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX,
to get user specified radio index for which attributes should be changed.
Pass this to individual drivers, so that the drivers can use this radio
index to change per-radio attributes when necessary. Currently, per-radio
attributes identified are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT
NL80211_ATTR_WIPHY_RETRY_LONG
NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD
NL80211_ATTR_WIPHY_COVERAGE_CLASS
NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM
By default, the radio index is set to -1. This means the attribute should
be treated as a global configuration. If the user has not specified any
index, then the radio index passed to individual drivers would be -1. This
would indicate that the attribute applies to all radios in that wiphy.

Currently, link station statistics for MLO are filled by mac80211.
But there are some statistics that kept by mac80211 might not be
accurate, so let the driver pre-fill the link statistics. The driver
can fill the values (indicating which field is filled, by setting the

Statistics that driver don't fill are filled by mac80211.
Hence, add link_sta_statistics callback to fill link station statistics
for MLO in sta_set_link_sinfo() by drivers.

Currently, RX stats packets are incremented for deflink member for
non-ML and multi-link(ML) station case. However, for ML station,
packets should be incremented based on the specific link.
Therefore, if a valid link_id is present, fetch the corresponding
link station information and increment the RX packets for that link.
For non-MLO stations, the deflink will still be used.

Currently, sinfo structure is supported to fill information at
deflink( or one of the links) level for station. This has problems
when applied to fetch multi-link(ML) station information.
Hence, if valid_links are present, support filling link_station
structure for each link.
This will be helpful to check the link related statistics during MLO.
Additionally, TXQ stats for pertid are applicable at station level
not at link level. Therefore check link_id is less then 0, before
filling TXQ stats in pertid stats.

Currently, sinfo->filled is for set in sta_set_sinfo() after filling
the corresponding fields in station_info structure for station statistics.
For non-ML stations, the fields are correctly filled from sta->deflink
and corresponding sinfo->filled bit are set, but for MLO any one of
link's data is filled and corresponding sinfo->filled bit is set.
For MLO before embed NL message, fields of sinfo structure like
bytes, packets, signal are updated with accumulated, best, least of all
links data. But some of fields like rssi, pertid don't make much sense
at MLO level.
Hence, to prevent misinterpretation, clear sinfo->filled for fields
which don't make much sense at MLO level. This will prevent filling
misleading values in NL message.

Currently, if a link gets removed in between for a station then
directly accumulated data will fall down to sum of other active links.
This will bring inconsistency in station dump statistics.
For instance, let's take Tx packets
- at t=0-> link-0:2 link-1:3 Tx packets => accumulated = 5
- at t=1-> link-0:4 link-1:6 Tx packets => accumulated = 10
let say at t=2, link-0 went down => link-0:0 link-1:7 => accumulated = 7
Here, suddenly accumulated Tx packets will come down to 7 from 10.
This is showing inconsistency.
Therefore, store link-0 data when it went down and add to accumulated
Tx packet = 11.
Hence, store the removed link statistics data in sta structure and
add it in accumulated statistics for consistency.

Currently, station_info structure is passed to fill station statistics
from mac80211/drivers. After NL message send to user space for requested
station statistics, memory for station statistics is freed in cfg80211.
Therefore, memory allocation/free for link station statistics should
also happen in cfg80211 only.
Hence, allocate the memory for link_station structure for all
possible links and free in cfg80211_sinfo_release_content().

Currently statistics are handled at link level for multi-link
operation(MLO). There is no provision to check accumulated statistics
for a multi-link(ML) station. Other statistics, such as signal, rates,
are also managed at the link level only.
Statistics such as packets, bytes, signal, rates, etc are useful to
provide overall overview for the ML stations.
Statistics such as packets, bytes are accumulated statistics at MLO level.
However, MLO statistics for rates and signal can not be accumulated since
it won't make much sense. Hence, handle other statistics such as signal,
rates, etc bit differently at MLO level.
The signal could be the best of all links-
e.g. if Link 1 has a signal strength of -70 dBm and Link 2 has -65 dBm,
the signal for MLO will be -65 dBm.
The rate could be determined based on the most recently updated link-
e.g. if link 1 has a rate of 300 Mbps and link 2 has a rate of 450 Mbps,
the MLO rate can be calculated based on the inactivity of each link.
If the inactive time for link 1 is 20 seconds and for link 2 is 10 seconds,
the MLO rate will be the most recently updated rate, which is link 2's
rate of 450 Mbps.
The inactive time, dtim_period and beacon_interval can be taken as the
least value of field from link level.
Similarly, other MLO level applicable fields are handled and the fields
which don't make much sense at MLO level, a subsequent change will handle
to embed NL message.
Hence, add accumulated and other statistics for MLO station if valid links
are present to represent comprehensive overview for the ML stations.

Currently, statistics is supported at deflink( or one of the links)
level for station. This has problems when applied to multi-link(ML)

Hence, add changes to support link level statistics to embed NL message

This will be helpful to check the link related statistics during MLO.
The statistics will be embedded into NL message as below:

Current implementation of NL80211_GET_STATION does not work for
multi-link operation(MLO) since in case of MLO only deflink (or one
of the links) is considered and not all links.
Therefore to support for MLO, add link_station_info structure
to account link level statistics for station.
Additionally, add valid_links in station_info structure to indicate
bitmap of valid links for MLO. This will be helpful to check the link
related statistics during MLO.

Currently, in supporting API's to fill sinfo structure from sta
structure, is mapped to fill the fields from sta->deflink. However,
for multi-link (ML) station, sinfo structure should be filled from
corresponding link_id.
Therefore, add link_id as an additional argument in supporting API's
for filling sinfo structure correctly. Link_id is set to -1 for non-ML
station and corresponding link_id for ML stations. In supporting API's
for filling sinfo structure, check for link_id, if link_id < 0, fill
the sinfo structure from sta->deflink, otherwise fill from
sta->link[link_id].
Current, changes are done at the deflink level i.e, pass -1 as link_id.
Actual link_id will be added in subsequent patches to support
station statistics for MLO.

Currently, when a non-DFS channel is brought up and the bandwidth is
expanded from 80 MHz to 160 MHz, where the primary 80 MHz is non-DFS
and the secondary 80 MHz consists of DFS channels, radar detection
fails if radar occurs in the secondary 80 MHz.
When the channel is switched from 80 MHz to 160 MHz, with the primary
80 MHz being non-DFS and the secondary 80 MHz consisting of DFS
channels, the radar required flag in the channel switch parameters
is set to true. However, when using a reserved channel context,
it is not updated in sdata, which disables radar detection in the
secondary 80 MHz DFS channels.
Update the radar required flag in sdata to fix this issue when using
a reserved channel context.

The changes focus on clarifying the setup_pi_matrix callback behavior

Improve the setup_pi_matrix callback documentation to clarify its purpose
and usage. The enhanced description explains that PSE PI devicetree nodes
are pre-parsed before this callback is invoked, and drivers should utilize
pcdev->pi[x]->pairset[y].np to map PSE controller hardware ports to their
corresponding Power Interfaces.
This clarification helps driver implementers understand the callback's
role in establishing the hardware-to-PI relationship mapping.

Alexander Duyck says:
====================
Add support for 25G, 50G, and 100G to fbnic
The fbnic driver up till now had avoided actually reporting link as the
phylink setup only supported up to 40G configurations. This changeset is
meant to start addressing that by adding support for 50G and 100G interface
types.
With that basic support added fbnic can then set those types based on the
EEPROM configuration provided by the firmware and then report those speeds
out using the information provided via the phylink call for getting the
link ksettings. This provides the basic MAC support and enables supporting
the speeds as well as configuring flow control.
After this I plan to add support for a PHY that will represent the SerDes
PHY being used to manage the link as we need a way to indicate link
training into phylink to prevent link flaps on the PCS while the SerDes is
in training, and then after that I will look at rolling support for our
PCS/PMA into the XPCS driver.
