4658b0eb94 docs: conf.py: avoid thousands of duplicate label warning on Sphinx
The autosectionlabel extension is nice, as it allows to refer to
a section by its name without requiring any extra tag to create
a reference name.

However, on its default, it has two serious problems:

1) the namespace is global. So, two files with different
   "introduction" section would create a label with the
   same name. This is easily solvable by forcing the extension
   to prepend the file name with:

	autosectionlabel_prefix_document = True

2) It doesn't work hierarchically. So, if there are two level 1
   sessions (let's say, one labeled "open" and another one "ioctl")
   and both have a level 2 "synopsis" label, both section 2 will
   have the same identical name.

   Currently, there's no way to tell Sphinx to create an
   hierarchical reference like:

		open / synopsis
		ioctl / synopsis

  This causes around 800 warnings. So, the fix should be to
  not let autosectionlabel to produce references for anything
  that it is not at a chapter level within any doc, with:

	autosectionlabel_maxdepth = 2

c44166fe5f docs: prevent warnings due to autosectionlabel
Changeset 58ad30cf91f0 ("docs: fix reference to core-api/namespaces.rst")
enabled a new feature at Sphinx: it will now generate index for each
document title, plus to each chapter inside it.

There's a drawback, though: one document cannot have two sections
with the same name anymore.

A followup patch will change the logic of autosectionlabel to
avoid most creating references for every single section title,
but still we need to be able to reference the chapters inside
a document.

There are a few places where there are two chapters with the
same name. This patch renames one of the chapters, in order to
avoid symbol conflict within the same document.

PS.: as I don't speach Chinese, I had some help from a friend
(Wen Liu) at the Chinese translation for "publishing patches"

2da1ed62d5 KVM: SVM: document KVM_MEM_ENCRYPT_OP, let userspace detect if SEV is available
Userspace has no way to query if SEV has been disabled with the
sev module parameter of kvm-amd.ko.  Actually it has one, but it
is a hack: do ioctl(KVM_MEM_ENCRYPT_OP, NULL) and check if it
returns EFAULT.  Make it a little nicer by returning zero for
SEV enabled and NULL argument, and while at it document the
ioctl arguments.

e4c2c0ff00 firmware: Add new platform fallback mechanism and firmware_request_platform()
In some cases the platform's main firmware (e.g. the UEFI fw) may contain
an embedded copy of device firmware which needs to be (re)loaded into the
peripheral. Normally such firmware would be part of linux-firmware, but in
some cases this is not feasible, for 2 reasons:

1) The firmware is customized for a specific use-case of the chipset / use
with a specific hardware model, so we cannot have a single firmware file
for the chipset. E.g. touchscreen controller firmwares are compiled
specifically for the hardware model they are used with, as they are
calibrated for a specific model digitizer.

2) Despite repeated attempts we have failed to get permission to
redistribute the firmware. This is especially a problem with customized
firmwares, these get created by the chip vendor for a specific ODM and the
copyright may partially belong with the ODM, so the chip vendor cannot
give a blanket permission to distribute these.

This commit adds a new platform fallback mechanism to the firmware loader
which will try to lookup a device fw copy embedded in the platform's main
firmware if direct filesystem lookup fails.

Drivers which need such embedded fw copies can enable this fallback
mechanism by using the new firmware_request_platform() function.

Note that for now this is only supported on EFI platforms and even on
these platforms firmware_fallback_platform() only works if
CONFIG_EFI_EMBEDDED_FIRMWARE is enabled (this gets selected by drivers
which need this), in all other cases firmware_fallback_platform() simply
always returns -ENOENT.

526ee72dfd debugfs: remove return value of debugfs_create_file_size()
No one checks the return value of debugfs_create_file_size, as it's not
needed, so make the return value void, so that no one tries to do so in
the future.

281d90e24f First set of new IIO device support, fatures and cleanups for the 5.7 cycle
Includes changes for the counter subsystem
 
 Core Feature
 * Explicitly handle sysfs values in dB, including correctly handling the
   needed postfix dB.
 * Add a TODO to suggest suitable activities for new contributors to IIO now
   the vast majority of drivers are out of staging (and the remaining ones
   there are 'hard'). Also update the TODO in staging to remove stale entries.
 
 Staging graduations
 * ad7192 ADC.
 
 New device support
 * ad5770r
   - New driver for this 6 channel DAC including DT bindings.
 * ad8366
   - Add supprot for the hmc1119 attenuator.
 * al3010
   - New driver supporting this Dyna-image light sensors.
   - Power management and DT bindings added in additional patches.
 * atlas-sensor
   - Add support for atlas DO-SM device.  Reads disolved oxygen in a solution.
 * gpap002x00f
   - New driver and bindings to support the GP2AP002A00F and GP2AP002S00F light
     and proximity sensors. There is some limited existing support in
     input.  The intent is to drop this driver once IIO driver is in place.
 * hmc425a
   - New driver for this attenuator.
 * icp10100
   - New driver for this presure sensor.
 * ltc2632
   - Add support for the ltc2636 8 channel DAC. Includes bindings and some
     tidying up of the driver.
 * inv_mpu6050
   - Support IAM20680, ICM20609, ICM20689 and ICM20690.
     Includes related tidy up and rework of low pass filter bandwidth
     handling to give suitable values for all chips.
 
 Binding conversions to yaml or missing bindings docs.
 * atlas-sensor, including consolidation of previous 3 separate docs into 1.
 * ad7923, previously no doc.
 * max1363, split into max1238 and max1363 to simplify yaml.
 * stm32-adc
 
 Features
 * (counter) 104-quad-8
   - Support a filter clock prescaler.
   - Support reporting of encoder cable status.
 * ad7124
   - Low pass filter support.
   - Debugfs interface to access registers directly.
 * ad8366
   - Support control of hardware gain.
 * inv_mpu6050
   - Runtime pm with autosuspend.
 * npcm adc
   - Add reset support. This is a breaking change if DT is not in sync,
     however this device is a BMC so the ecosystem is closed enought that
     this should not be a problem.
 * srf04
   - Add power management with DT bindings for the GPIO.
 * stm32-timer-trigger
   - Power management.
 * (counter) stm32-timer-cnt
   - Power management.
 * vcnl4000
   - Enable runtime PM for devices that don't use on demand measurement.
 
 Cleanups and minor fixes
 * core
   - Avoid double read when using debugfs.  Whilst we provide no guarantees
     on lack of side effects using the debugfs interfaces, this one is
     generate unexpected results so let us tidy it up.
 * dac/Kconfig
   - Alphabetic order.
 * ad5755
   - Grammar and minor other fixes.
 * ad7124
   - Fail probe if get_voltage fails as no meaningful readings can be had
     without knowing the external reference.
   - Switch to selection between different channel attributes rather than
     building the arrays at runtime.
   - Remove the spi_device_id table as the driver cannot be probled without
     more information that can be provided without dt.

     this part out of staging.
 * ad9292
   - Use new SPI transfer delay structure.

     control of userspace.
   - Always execute full reset on devices supporting spi. It does no harm
     when using i2c and makes for simpler code.
   - Reduce over the top sleep times for vddio regulator power up.
   - Greatly simplify power and engine management.
   - Fix some delays in polled reads (only visible due to other changes)

5190044c29 modpost: move the namespace field in Module.symvers last
In order to preserve backwards compatability with kmod tools, we have to
move the namespace field in Module.symvers last, as the depmod -e -E
option looks at the first three fields in Module.symvers to check symbol
versions (and it's expected they stay in the original order of crc,
symbol, module).

In addition, update an ancient comment above read_dump() in modpost that
suggested that the export type field in Module.symvers was optional. I
suspect that there were historical reasons behind that comment that are
no longer accurate. We have been unconditionally printing the export
type since 2.6.18 (commit bd5cbcedf44), which is over a decade ago now.

Fix up read_dump() to treat each field as non-optional. I suspect the
original read_dump() code treated the export field as optional in order
to support pre <= 2.6.18 Module.symvers (which did not have the export
type field). Note that although symbol namespaces are optional, the
field will not be omitted from Module.symvers if a symbol does not have
a namespace. In this case, the field will simply be empty and the next
delimiter or end of line will follow.

regulator: mp886x: Document MP8867 support
MP8867 is an I2C-controlled adjustable voltage regulator made by
Monolithic Power Systems. The difference between MP8867 and MP8869
are:
1.If V_BOOT, the vref of MP8869 is fixed at 600mv while vref of MP8867
is determined by the I2C control.
2.For MP8867, when setting voltage, if the steps is within 5, we need
to manually set the GO_BIT to 0.

 DWC2 got support for STM32MP15 and a couple RockChip SoCs while DWC3
 learned about Amlogic A1 family.
 
 Apart from these, we have a few spelling fixes and other minor
 non-critical fixes all over the place.

f2c2e71764 usb: gadget: add raw-gadget interface
USB Raw Gadget is a kernel module that provides a userspace interface for
the USB Gadget subsystem. Essentially it allows to emulate USB devices
from userspace. Enabled with CONFIG_USB_RAW_GADGET. Raw Gadget is
currently a strictly debugging feature and shouldn't be used in
production.

Raw Gadget is similar to GadgetFS, but provides a more low-level and
direct access to the USB Gadget layer for the userspace. The key
differences are:

1. Every USB request is passed to the userspace to get a response, while
   GadgetFS responds to some USB requests internally based on the provided
   descriptors. However note, that the UDC driver might respond to some
   requests on its own and never forward them to the Gadget layer.

2. GadgetFS performs some sanity checks on the provided USB descriptors,
   while Raw Gadget allows you to provide arbitrary data as responses to
   USB requests.

3. Raw Gadget provides a way to select a UDC device/driver to bind to,
   while GadgetFS currently binds to the first available UDC.

4. Raw Gadget uses predictable endpoint names (handles) across different
   UDCs (as long as UDCs have enough endpoints of each required transfer
   type).

5. Raw Gadget has ioctl-based interface instead of a filesystem-based one.
