Set DMA mask to 32-bit while allocating the MSI target address so that
the address is usable for both 32-bit and 64-bit MSI capable devices.
Throw a warning if it fails to set the mask to 32-bit to alert that
devices that are only 32-bit MSI capable may not work properly.

Added processor thermal device mail box interface for workload hints
setting. These hints will give indication to hardware to better manage
power and thermals. The supported hints are:
idle
semi_active
burusty
sustained
battery_life
For example when the system is on battery, the hardware can be less
aggressive in power ramp up.
This will create an attribute group at
/sys/bus/pci/devices/0000:00:04.0/workload_request
This folder contains two attributes:
workload_available_types : (RO): This shows available workload types
workload_type: (RW) : Allows to set and get current workload type
setting

Add support for RFIM (Radio Frequency Interference Mitigation) support
via processor thermal PCI device. This drivers allows adjustment of
FIVR (Fully Integrated Voltage Regulator) and DDR (Double Data Rate)
frequencies to avoid RF interference with WiFi and 5G.
Switching voltage regulators (VR) generate radiated EMI or RFI at the
fundamental frequency and its harmonics. Some harmonics may interfere
with very sensitive wireless receivers such as Wi-Fi and cellular that
are integrated into host systems like notebook PCs. One of mitigation
methods is requesting SOC integrated VR (IVR) switching frequency to a
small % and shift away the switching noise harmonic interference from
radio channels. OEM or ODMs can use the driver to control SOC IVR
operation within the range where it does not impact IVR performance.
DRAM devices of DDR IO interface and their power plane can generate EMI
at the data rates. Similar to IVR control mechanism, Intel offers a
mechanism by which DDR data rates can be changed if several conditions
are met: there is strong RFI interference because of DDR; CPU power
management has no other restriction in changing DDR data rates;
PC ODMs enable this feature (real time DDR RFI Mitigation referred to as
DDR-RFIM) for Wi-Fi from BIOS.
This change exports two folders under /sys/bus/pci/devices/0000:00:04.0.
One folder "fivr" contains all attributes exposed for controling FIVR
features. The other folder "dvfs" contains all attributes for DDR
features.
Changes done to implement:
- New module for rfim interfaces
- Two new per processor features for DDR and FIVR
- Enable feature for Tiger Lake (FIVR only) and Alder Lake
The attributes exposed and explanation:
FIVR attributes
vco_ref_code_lo (RW): The VCO reference code is an 11-bit field and
controls the FIVR switching frequency. This is the 3-bit LSB field.
vco_ref_code_hi (RW): The VCO reference code is an 11-bit field and
controls the FIVR switching frequency. This is the 8-bit MSB field.
spread_spectrum_pct (RW): Set the FIVR spread spectrum clocking
percentage
spread_spectrum_clk_enable (RW): Enable/disable of the FIVR spread
spectrum clocking feature
rfi_vco_ref_code (RW): This field is a read only status register which
reflects the current FIVR switching frequency
fivr_fffc_rev (RW): This field indicated the revision of the FIVR HW.
DVFS attributes
rfi_restriction_run_busy (RW): Request the restriction of specific DDR
data rate and set this value 1. Self reset to 0 after operation.
rfi_restriction_err_code (RW): Values: 0 :Request is accepted, 1:Feature
disabled, 2: the request restricts more points than it is allowed
rfi_restriction_data_rate_Delta (RW): Restricted DDR data rate for RFI
protection: Lower Limit
rfi_restriction_data_rate_Base (RW): Restricted DDR data rate for RFI
protection: Upper Limit
ddr_data_rate_point_0 (RO): DDR data rate selection 1st point
ddr_data_rate_point_1 (RO): DDR data rate selection 2nd point

The Processor Thermal PCI device supports multiple features. Currently
we export only RAPL. But we need more features from this device exposed
for Tiger Lake and Alder Lake based platforms. So re-structure the
current MMIO interface, so that more features can be added cleanly.
No functional changes are expected with this change.
Changes done in this patch:
- Using PCI_DEVICE_DATA(), hence names of defines changed
- Move RAPL MMIO code to its own module
- Move the RAPL MMIO offsets to RAPL MMIO module
- Adjust Kconfig dependency of PROC_THERMAL_MMIO_RAPL
- Per processor driver data now contains the supported features
- Moved all the common data structures and defines to a common header
file
- This new header file contains all the processor_thermal_* interfaces
- Based on the features supported the module interface is called
- Each module atleast provides one add and one remove function

The PAT bit is in different locations for 4k and 2M/1G page table

Add a definition for _PAGE_LARGE_CACHE_MASK to represent the three

and use it in the definition of PMD_FLAGS_DEC_WP to get the correct PAT

Add support for M_CAN controller on Intel Elkhart Lake attached to the PCI bus.
It integrates the Bosch M_CAN controller with Message RAM and the wrapper IP
block with additional registers which all of them are within the same MMIO
range.
Currently only interrupt control register from wrapper IP is used and the MRAM
configuration is expected to come from the firmware via "bosch,mram-cfg" device
property and parsed by m_can.c core.
Initial implementation is done by Felipe Balbi while he was working at Intel
with later changes from Raymond Tan and me.

This is a preparatory patch for upcoming PCI based M_CAN devices. The current
PM implementation would cause PCI based drivers to enable PM twice, once when
the PCI device is added and a second time in m_can_class_register(). This will
cause 'Unbalanced pm_runtime_enable!' to be logged, and is a situation that
should be avoided.
Therefore, in anticipation of PCI devices, move PM enabling out from M_CAN
class registration to its only user, the m_can_platform driver.

When CAN_ISOTP_SF_BROADCAST is set in the CAN_ISOTP_OPTS flags the CAN_ISOTP
socket is switched into functional addressing mode, where only single frame
(SF) protocol data units can be send on the specified CAN interface and the
given tp.tx_id after bind().
In opposite to normal and extended addressing this socket does not register a
CAN-ID for reception which would be needed for a 1-to-1 ISOTP connection with a
segmented bi-directional data transfer.
Sending SFs on this socket is therefore a TX-only 'broadcast' operation.

In zonefs_file_dio_append(), the pages obtained using
bio_iov_iter_get_pages() are not released on completion of the
REQ_OP_APPEND BIO, nor when bio_iov_iter_get_pages() fails.
Furthermore, a call to bio_put() is missing when
bio_iov_iter_get_pages() fails.
Fix these resource leaks by adding BIO resource release code (bio_put()i
and bio_release_pages()) at the end of the function after the BIO
execution and add a jump to this resource cleanup code in case of
bio_iov_iter_get_pages() failure.
While at it, also fix the call to task_io_account_write() to be passed
the correct BIO size instead of bio_iov_iter_get_pages() return value.

Currently, the driver gets the max rss size from configuration
file when initialization. Both the PF and VF share the same
max rss size, and no more than 128.
For DEVICE_VERSION_V3, the max rss size for PF can be up to
512, so there is a new field in configuration file to store it,
the old filed is used for VF.
To be compatible with boards using old configure file, the PF
will use the old filed if the one is zero.
For the rss size may be larger than 256, so the type of
rss_indirection_tbl of struct hclge_vport should be changed to

Currently, the HNS3 driver only supports offload for tc number
and prio_tc. This patch adds support for other qopts, including
queues count and offset for each tc.
When enable tc mqprio offload, it's not allowed to change
queue numbers by ethtool. For hardware limitation, the queue
number of each tc should be power of 2.
For the queues is not assigned to each tc by average, so it's
should return vport->alloc_tqps for hclge_get_max_channels().

For BOs imported from outside of amdgpu, setting of amdgpu_gem_object_funcs
was missing in amdgpu_dma_buf_create_obj. Fix by refactoring BO creation
and amdgpu_gem_object_funcs setting into single function called
from both code paths.
Fixes: d693def4fd1c ("drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver")
v2: Use use amdgpu_gem_object_create() directly
v3: fix warning

The Samsung touchkey controllers are often used with external pull-up
for the interrupt line and the I2C lines, so we might need to enable
a regulator to bring the lines into usable state. Otherwise, this might
cause spurious interrupts and reading from I2C will fail.
Implement support for a "vddio-supply" that is enabled by the
tm2-touchkey driver so that the regulator gets enabled when needed.

Convert the device tree bindings for tm2-touchkey to the YAML format.
While we're at it, clarify the descriptions a bit to make it clear that
this driver can be used for many different MCUs that all implement
a similar I2C protocol. Depending on the MCU the voltage requirements
may be different, on some devices the controller uses 2.2V, 2.8V or
even 3.3V for vcc-supply instead of 1.8V.

Russell King says:
====================
Add support for VSOL V2801F/CarlitoxxPro CPGOS03 GPON module
This patch set adds support for the V2801F / CarlitoxxPro module. This
requires two changes:
1) the module only supports single byte reads to the ID EEPROM,
while we need to still permit sequential reads to the diagnostics
EEPROM for atomicity reasons.
2) we need to relax the encoding check when we have no reported
capabilities to allow 1000base-X based on the module bitrate.
Thanks to Pali Rohár for responsive testing over the last two days.
(Resending, dropping the utf-8 characters in Pali's name so the patches
get through vger. Added Andrew's r-b tags.)

Do not check the encoding when deriving 1000BASE-X from the bitrate
when no other modes are discovered. Some GPON modules (VSOL V2801F
and CarlitoxxPro CPGOS03-0490 v2.0) indicate NRZ encoding with a
1200Mbaud bitrate, but should be driven with 1000BASE-X on the host
side.

Add a workaround for the detection of VSOL V2801F / CarlitoxxPro
CPGOS03-0490 v2.0 GPON module which CarlitoxxPro states needs single
byte I2C reads to the EEPROM.
Pali Rohár reports that he also has a CarlitoxxPro-based V2801F module,
which reports a manufacturer of "OEM". This manufacturer can't be
matched as it appears in many different modules, so also match the part
number too.
