2546c60004 platform/x86: Add Intel Software Defined Silicon driver
Intel Software Defined Silicon (SDSi) is a post manufacturing mechanism for
activating additional silicon features. Features are enabled through a
license activation process.  The SDSi driver provides a per socket, sysfs
attribute interface for applications to perform 3 main provisioning
functions:

1. Provision an Authentication Key Certificate (AKC), a key written to
   internal NVRAM that is used to authenticate a capability specific
   activation payload.

2. Provision a Capability Activation Payload (CAP), a token authenticated
   using the AKC and applied to the CPU configuration to activate a new
   feature.

3. Read the SDSi State Certificate, containing the CPU configuration
   state.

The operations perform function specific mailbox commands that forward the
requests to SDSi hardware to perform authentication of the payloads and
enable the silicon configuration (to be made available after power
cycling).

The SDSi device itself is enumerated as an auxiliary device from the
intel_vsec driver and as such has a build dependency on CONFIG_INTEL_VSEC.

83e3966411 ARM: SoC fixes for 5.17
This is a fairly large set of bugfixes, most of which had
 been sent a while ago but only now made it into the soc tree:
 
 Maintainer file updates:
 
  - Claudiu Beznea now co-maintains the at91 soc family,
    replacing Ludovic Desroches.
 
  - Michael Walle maintains the sl28cpld drivers
 
  - Alain Volmat and Raphael Gallais-Pou take over some
    drivers for ST platforms
 
  - Alim Akhtar is an additional reviewer for Samsung platforms
 
 Code fixes:
 
  - Op-tee had a problem with object lifetime that needs
    a slightly complex fix, as well as another bug with
    error handling.
 
  - Several minor issues for the OMAP platform, including
    a regression with the timer
 
  - A Kconfig change to fix a build-time issue on Intel
    SoCFPGA
 
 Device tree fixes:
 
  - The Amlogic Meson platform fixes a boot regression on
    am1-odroid, a spurious interrupt, and a problem with
    reserved memory regions
 
  - In the i.MX platform, several bug fixes are needed to
    make devices work correctly: SD card detection,
    alarmtimer, and sound card on some board. One patch
    for the GPU got in there by accident and gets reverted
    again.
 
  - TI K3 needs a fix for J721S2 serial port numbers
 
  - ux500 needs a fix to mount the SD card as root on
    the Skomer phone.

78d5e9e299 i2c: designware: Add AMD PSP I2C bus support
Implement an I2C controller sharing mechanism between the host (kernel)
and PSP co-processor on some platforms equipped with AMD Cezanne SoC.

On these platforms we need to implement "software" i2c arbitration.
Default arbitration owner is PSP and kernel asks for acquire as well
as inform about release of the i2c bus via mailbox mechanism.

The solution is similar to i2c-designware-baytrail.c implementation, where
we are using a generic i2c-designware-* driver with a small "wrapper".

In contrary to baytrail semaphore implementation, beside internal
acquire_lock() and release_lock() methods we are also applying quirks to
lock_bus() and unlock_bus() global adapter methods. With this in place
all i2c clients drivers may lock i2c bus for a desired number of i2c
transactions (e.g. write-wait-read) without being aware of that such bus
is shared with another entity.

Modify i2c_dw_probe_lock_support() to select correct semaphore
implementation at runtime, since now we have more than one available.

Configure new matching ACPI ID "AMDI0019" and register
ARBITRATION_SEMAPHORE flag in order to distinguish setup with PSP
arbitration.

Add myself as a reviewer for I2C DesignWare in order to help with reviewing
and testing possible changes touching new i2c-designware-amdpsp.c module.

Second set of fixes for v5.17. This is the first pull request with
 both driver and stack patches.
 
 Most important here are a regression fix for brcmfmac USB devices and
 an iwlwifi fix for use after free when the firmware was missing. We
 have new maintainers for ath9k and wcn36xx as well as ath6kl is now
 orphaned. Also smaller fixes to iwlwifi and stack.

   arguments from BPF progs for non-x86 architectures,
   from Ilya Leoshkevich.

8) Rework port members in struct bpf_sk_lookup and struct bpf_sock to be
   of 16-bit field with anonymous zero padding, from Jakub Sitnicki.

9) Add new bpf_copy_from_user_task() helper to read memory from a different
   task than current. Add ability to create sleepable BPF iterator progs,
   from Kenny Yu.

10) Implement XSK batching for ice's zero-copy driver used by AF_XDP and
    utilize TX batching API from XSK buffer pool, from Maciej Fijalkowski.

11) Generate temporary netns names for BPF selftests to avoid naming
    collisions, from Hangbin Liu.

12) Implement bpf_core_types_are_compat() with limited recursion for
    in-kernel usage, from Matteo Croce.

Adds 'dmas' and 'dma-names' in the example which were missing from
the txt file.
Changes 'interrupts' and 'interrupt-names' from optional to
required properties.
Changes 'op-modes', 'serial-dir' to optional properties as they are
not needed if the McASP is used only as GPIO.
Changes 'tdm-slots' to required property only for I2S operation mode.

Adds the yaml file in the 'MAINTAINERS' under the heading 'TEXAS

spi: make remove callback a void function
Merge series from Uwe Kleine-König <u.kleine-koenig@pengutronix.de>:

this series goal is to change the spi remove callback's return value to void.
After numerous patches nearly all drivers already return 0 unconditionally.
The four first patches in this series convert the remaining three drivers to
return 0, the final patch changes the remove prototype and converts all
implementers.

a85e4c5208 peci: Add peci-aspeed controller driver
ASPEED AST24xx/AST25xx/AST26xx SoCs support the PECI electrical
interface (a.k.a PECI wire) that provides a communication channel with
Intel processors.
This driver allows BMC to discover devices connected to it and
communicate with them using PECI protocol.

6523d3b2ff peci: Add core infrastructure
Intel processors provide access for various services designed to support
processor and DRAM thermal management, platform manageability and
processor interface tuning and diagnostics.
Those services are available via the Platform Environment Control
Interface (PECI) that provides a communication channel between the
processor and the Baseboard Management Controller (BMC) or other
platform management device.

This change introduces PECI subsystem by adding the initial core module
and API for controller drivers.

db405774f6 MAINTAINERS: Add entry for fbdev core
Ever since Tomi extracted the core code in 2014 it's been defacto me
maintaining this, with help from others from dri-devel and sometimes
Linus (but those are mostly merge conflicts):

$ git shortlog -ns  drivers/video/fbdev/core/ | head -n5
    35  Daniel Vetter
    23  Linus Torvalds
    10  Hans de Goede
     9  Dave Airlie
     6  Peter Rosin

I think ideally we'd also record that the various firmware fb drivers
(efifb, vesafb, ...) are also maintained in drm-misc because for the
past few years the patches have either been to fix handover issues
with drm drivers, or caused handover issues with drm drivers. So any
other tree just doesn't make sense. But also, there's plenty of
outdated MAINTAINER entries for these with people and git trees that
haven't been active in years, so maybe let's just leave them alone.
And furthermore distros are now adopting simpledrm as the firmware fb
driver, so hopefully the need to care about the fbdev firmware drivers
will go down going forward.

Note that drm-misc is group maintained, I expect that to continue like
we've done before, so no new expectations that patches all go through
my hands. That would be silly. This also means I'm happy to put any
other volunteer's name in the M: line, but otherwise git log says I'm
the one who's stuck with this.

7938f42181 dma-buf-map: Rename to iosys-map
Rename struct dma_buf_map to struct iosys_map and corresponding APIs.
Over time dma-buf-map grew up to more functionality than the one used by
dma-buf: in fact it's just a shim layer to abstract system memory, that
can be accessed via regular load and store, from IO memory that needs to
be acessed via arch helpers.

The idea is to extend this API so it can fulfill other needs, internal
to a single driver. Example: in the i915 driver it's desired to share
the implementation for integrated graphics, which uses mostly system
memory, with discrete graphics, which may need to access IO memory.

The conversion was mostly done with the following semantic patch:

	@r1@
	@@
	- struct dma_buf_map
	+ struct iosys_map

	@r2@
	@@
	(
	- DMA_BUF_MAP_INIT_VADDR
	+ IOSYS_MAP_INIT_VADDR
	|
	- dma_buf_map_set_vaddr
	+ iosys_map_set_vaddr
	|
	- dma_buf_map_set_vaddr_iomem
	+ iosys_map_set_vaddr_iomem
	|
	- dma_buf_map_is_equal
	+ iosys_map_is_equal
	|
	- dma_buf_map_is_null
	+ iosys_map_is_null
	|
	- dma_buf_map_is_set
	+ iosys_map_is_set
	|
	- dma_buf_map_clear
	+ iosys_map_clear
	|
	- dma_buf_map_memcpy_to
	+ iosys_map_memcpy_to
	|
	- dma_buf_map_incr
	+ iosys_map_incr
	)

	@@
	@@
	- #include <linux/dma-buf-map.h>
	+ #include <linux/iosys-map.h>

Then some files had their includes adjusted and some comments were
update to remove mentions to dma-buf-map.

Since this is not specific to dma-buf anymore, move the documentation to
the "Bus-Independent Device Accesses" section.

v2:
  - Squash patches

v3:
  - Fix wrong removal of dma-buf.h from MAINTAINERS
  - Move documentation from dma-buf.rst to device-io.rst

v4:
  - Change documentation title and level

494a2c2b27 ata fixes for 5.17-rc3
* Sergey volunteered to be a reviewer for the Renesas R-Car SATA
   driver and PATA drivers. Update the MAINTAINERS file accordingly.
 
 * Regression fix: add a horkage flag to prevent accessing the log
   directory log page with SATADOM-ML 3ME SATA devices as they react
   badly to reading that log page (from Anton).
