They are used way too often in this file, in some ways that are actually
wrong. Almost all of these are already known by the compiler and CPU so
just remove them all as none of these should be on any "hot paths" where
it actually matters.

In many cases a function that supports SuperSpeed can very well
operate in SuperSpeedPlus, if a gadget controller supports it,
as the endpoint descriptors (and companion descriptors) are
generally identical and can be re-used. This is true for two
commonly used functions: Android's ADB and MTP. So we can simply
assign the usb_function's ssp_descriptors array to point to its
ss_descriptors, if available. Similarly, we need to allow an
epfile's ioctl for FUNCTIONFS_ENDPOINT_DESC to correctly
return the corresponding SuperSpeed endpoint descriptor in case
the connected speed is SuperSpeedPlus as well.
The only exception is if a function wants to implement an
Isochronous endpoint capable of transferring more than 48KB per
service interval when operating at greater than USB 3.1 Gen1
speed, in which case it would require an additional SuperSpeedPlus
Isochronous Endpoint Companion descriptor to be returned as part
of the Configuration Descriptor. Support for that would need
to be separately added to the userspace-facing FunctionFS API
which may not be a trivial task--likely a new descriptor format
(v3?) may need to be devised to allow for separate SS and SSP
descriptors to be supplied.

Get "syscon" pcie_ctrl offset from the argument of "ti,syscon-pcie-ctrl"
phandle. Previously a subnode to "syscon" node was added which has the
exact memory mapped address of pcie_ctrl but now the offset of pcie_ctrl
within "syscon" is now being passed as argument to "ti,syscon-pcie-ctrl"
phandle.
If the offset is not provided in "ti,syscon-pcie-ctrl", the
full memory mapped address of pcie_ctrl is used in order to maintain old
DT compatibility.

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
ddr_data_rate_point_2 (RO): DDR data rate selection 3rd 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

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.

For the max rss size of PF may be up to 512, the max queue
number of single tc may be up to 512 too. For the total queue
numbers may be up to 1280, so the queue offset of each tc may
be more than 1024. So adjust the rss tc mode configuration
command, including extend tc size field from 10 bits to 11
bits, and extend tc size field from 3 bits to 4 bits.

For the max rss size of PF may be up to 512, so adjust the
command of configuring rss indirection table to support
queue id larger than 255. The width of queue id is extended
from 8 bits to 10 bits. The high 2 bits are stored in filed
rss_qid_h when the queue id is larger than 255.

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
u16 as well.

Some new device supports forwarding packet to queues of specified
TC when flow director rule hit. So add support to configure flow
director rule by tc flower. To avoid rule conflict, add a new flow
director mode HCLGE_FD_TC_FLOWER_ACTIVE, and only one mode can be
active at the same time.

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.
