Register cfg80211_sar_capa with type NL80211_SAR_TYPE_POWER and four
frequency ranges for configurations in unit of 0.25 dBm. And handle
callback set_sar_specs.
Originally, TX power has three main parameters, i.e. power base,
power by rate, and power limit. The formula can be simply considered
as TX power = power base + min(power by rate, power limit). With the
support of SAR which can be treated as another power limit, there is
one more parameter for TX power. And the formula will evolve into
TX power = power base + min(power by rate, power limit, power sar).
Besides, debugfs tx_pwr_tbl is also refined to show SAR information.
The following is an example for the difference.
Before supporting SAR,
-----------------------------------
...
path rate pwr base (byr lmt ) rem
A CCK_1M 66(0x42) 78 -12 ( 12 -12) 0
A CCK_2M 66(0x42) 78 -12 ( 8 -12) 0
...
-----------------------------------
After supporting SAR and making some configurations,
-----------------------------------
...
path rate pwr base (byr lmt sar ) rem
A CCK_1M 62(0x3e) 78 -16 ( 12 -12 -16) 0
A CCK_2M 62(0x3e) 78 -16 ( 8 -12 -16) 0

Declare this function allows us to use customized scanning policy.
By doing so we can be more time efficient on each scan. In order to
make existing coex mechanism work as usual, firmware notifies driver
on each channel switch event, then decide antenna ownership based on
the current channel/band. Do note that this new mechanism affects
throughput more than the sw_scan we used to have, but the overall
average throughput is not affected since each scan take less time.
Since the firmware size is limited, we only support probe requests
with custom IEs length under 128 bytes for now, if any user space
tools requires more than that, we'll introduce related changes
afterwards. For backward compatibility, we fallback to sw_scan when
using older firmware that does not support this feature.

There needs to be a check to prevent negative offsets for
setting->index. I have reviewed this code and I think that the
"if (block->instance_count <= instance)" check in __query_block() will
prevent this from resulting in an out of bounds access. But it's
still worth fixing.

STB (Smart Trace Buffer), is a debug trace buffer that isolates the
failures by analyzing the last running feature of a system. This
non-intrusive way always runs in the background and stores the trace
into the SoC.
This patch enables the STB feature by passing module param
"enable_stb=1" while loading the driver and provides mechanism to

E822 devices on supported platforms can generate a cross timestamp
between the platform ART and the device time. This process allows for
very precise measurement of the difference between the PTP hardware
clock and the platform time.
This is only supported if we know the TSC frequency relative to ART, so
we do not enable this unless the boot CPU has a known TSC frequency (as
required by convert_art_ns_to_tsc).
Because PCIe PTM support is not available on all platforms, introduce
CONFIG_ICE_HWTS and make it depend on X86 where we know the support
exists.

Once the E822 device has sent and received one packet, the hardware
computes the internal delay of the PHY using a process known as Vernier
calibration. This calibration calculates a more accurate offset for the
Tx and Rx timestamps. To make use of this offset, we need to exit the
bypass mode. This cannot be done until the PHY has completed offset
calibration, as indicated by the offset valid bits.
To handle this, introduce a kthread work item which will poll the offset
valid bits every few milliseconds seeing if it is safe to exit bypass
mode.
Once we have finished calibrating the offsets, we can program the total
Tx and Rx offset registers and turn off the bypass bit. This allows the
hardware to include the more precise vernier calibration offset, and
improves the timestamp precision.

Implement support for the basic operations needed to enable the PTP
hardware clock on E822 devices.
This includes implementations for the various PHY access functions, as
well as the ability to start and stop the PHY timers. This is different
from the E810 device because the configuration depends on link speed, so
we cannot just start the PHYs immediately. We must wait until the link
is up to get proper values for the speed based initialization.

When we enable support for E822 devices, there are some additional
steps required to initialize the PTP hardware clock. To make this easier
to implement as device-specific behavior, refactor the register setups
in ice_ptp_init_owner to a new ice_ptp_init_phc function defined in
ice_ptp_hw.c
This function will have a common section, and an e810 specific
sub-implementation.
This will enable easily extending the functionality to cover the E822
specific setup required to initialize the hardware clock generation
unit. It also makes it clear which steps are E810 specific vs which ones
are necessary for all ice devices.

The ice_ptp_hw.c file introduced a bunch of uses of "int status" instead
of the more traditional "int err" or "int ret". These are actually
traditional Linux error codes (as opposed to the recently removed
ice_status enumeration values).
We're about to add a bunch of new functions to ice_ptp_hw.c. It's
normally preferred in the ice driver to use "int ret" or "int err" when
dealing with error code values.
Instead of making the new functions use "int status" lets just fix all
of ice_ptp_hw.c to use "int err". This will match the new functions and
ensures a consistent style across at least the PTP related files.

The tstamp_config structure is being set inside of
ice_ptp_cfg_timestamp, which is the function used to set Tx and
Rx timestamping during initialization.
This function is also used in order to set the PHY port timestamping
status. However, it makes sense to always set the tstamp_config directly
whenever the ice_set_tx_tstamp or ice_set_rx_tstamp functions are
called.
Move assignment of tstamp_config into the related functions and out of
ice_ptp_cfg_timestamp.
Now that we assign the timestamp mode in the relevant functions, we no
longer modify the config value in ice_set_timestamp_mode. In turn, we
no longer want to copy that config value into the PF cached structure.
Instead, this is now the source of truth for actual configuration. On
success of ice_set_timestamp_mode, copy the real configured mode back to
report it out to userspace.

A future change will add additional possible increment values for the
E822 device support. To handle this, we want to look up the increment
value to use instead of hard coding it to the nominal value for E810
devices. Introduce ice_base_incval as a function to get the best nominal
increment value to use.
For now, it just returns the E810 value, but will be refactored in the
future to look up the value based on the device type and configured
clock frequency.

The PF reset does not reset PHC and PHY clocks so it's unnecessary to
stop them and reinitialize after the reset.
Configuring timestamping changes the VSI fields so it needs to be
performed after VSIs are initialized, which was not done in case of a

sample external voltages and monitor on-die operating conditions, such
as temperature and supply voltage levels. The AMS has two SYSMON blocks.
PL-SYSMON block is capable of monitoring off chip voltage and
temperature.
PL-SYSMON block has DRP, JTAG and I2C interface to enable monitoring
from an external master. Out of these interfaces currently only DRP is
supported. Other block PS-SYSMON is memory mapped to PS.
The AMS can use internal channels to monitor voltage and temperature as
well as one primary and up to 16 auxiliary channels for measuring
external voltages.
The voltage and temperature monitoring channels also have event capability
which allows to generate an interrupt when their value falls below or
raises above a set threshold.

This patch introduces a new helper routine - fwnode_iomap(), which
allows to map the memory mapped IO for a given device node.
This implementation does not cover the ACPI case and may be expanded
in the future. The main purpose here is to be able to develop resource
provider agnostic drivers.

Not sure what the thinking was here, as lost to history, but the
variable is clearly not used so get rid of it.
Warning seen with clang W=1 tests (may be present with other compilers
and build options).
