  - Aditya Srivastava has been working on improvements to the kernel-doc

  - Thorsten continues his work on reporting-issues.rst and related

Linus Torvalds 0c85556318 ARM: platform support for Apple M1
The Apple M1 is the processor used it all current generation Apple
 Macintosh computers. Support for this platform so far is rudimentary,
 but it boots and can use framebuffer and serial console over a special
 USB cable.
 
 Support for several essential on-chip devices (USB, PCIe, IOMMU, NVMe)
 is work in progress but was not ready in time.
 
 A very detailed description of what works is in the merge commit
 and on the AsahiLinux wiki.

Linus Torvalds 37f00ab4a0 ARM: SoC drivers for v5.13
Updates for SoC specific drivers include a few subsystems that
 have their own maintainers but send them through the soc tree:
 
 TEE/OP-TEE:
  -  Add tracepoints around calls to secure world
 
 Memory controller drivers:
  - Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms
  - Add debug statistics to Tegra20 memory controller
  - Update Tegra bindings and convert to dtschema
 
 ARM SCMI Firmware:
  - Support for modular SCMI protocols and vendor specific extensions
  - New SCMI IIO driver
  - Per-cpu DVFS
 
 The other driver changes are all from the platform maintainers
 directly and reflect the drivers that don't fit into any other
 subsystem as well as treewide changes for a particular platform.
 
 SoCFPGA:
  - Various cleanups contributed by Krzysztof Kozlowski
 
 Mediatek:
  - add MT8183 support to mutex driver
  - MMSYS: use per SoC array to describe the possible routing
  - add MMSYS support for MT8183 and MT8167
  - add support for PMIC wrapper with integrated arbiter
  - add support for MT8192/MT6873
 
 Tegra:
  - Bug fixes to PMC and clock drivers
 
 NXP/i.MX:
  - Update SCU power domain driver to keep console domain power on.
  - Add missing ADC1 power domain to SCU power domain driver.
  - Update comments for single global power domain in SCU power domain
    driver.
  - Add i.MX51/i.MX53 unique id support to i.MX SoC driver.
 
 NXP/FSL SoC driver updates for v5.13
  - Add ACPI support for RCPM driver
  - Use generic io{read,write} for QE drivers after performance optimized
    for PowerPC
  - Fix QBMAN probe to cleanup HW states correctly for kexec
  - Various cleanup and style fix for QBMAN/QE/GUTS drivers
 
 OMAP:
  - Preparation to use devicetree for genpd
  - ti-sysc needs iorange check improved when the interconnect target module
    has no control registers listed
  - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
    issues with missing resources and unnecessary deferred probe
  - ti-sysc debug option can now detect more devices
  - ti-sysc now warns if an old incomplete devicetree data is found as we
    now rely on it being complete for am3 and 4
  - soc init code needs to check for prcm and prm nodes for omap4/5 and dra7
  - omap-prm driver needs to enable autoidle retention support for omap4
  - omap5 clocks are missing gpmc and ocmc clock registers
  - pci-dra7xx now needs to use builtin_platform_driver instead of using
    builtin_platform_driver_probe for deferred probe to work
 
 Raspberry Pi:
  - Fix-up all RPi firmware drivers so as for unbind to happen in an
    orderly fashion
  - Support for RPi's PoE hat PWM bus
 
 Qualcomm
  - Improved detection for SCM calling conventions

 Lots of little churn in here, and some larger churn as well.  Major
 things are:

 	  this failed "experiment".
 	- removal of the Google gasket driver, turns out no one wanted
 	  to maintain it or cares about it anymore, so they asked for it
 	  to be removed.
 	- comedi finally moves out of the staging directory into
 	  drivers/comedi/  This is one of the oldest kernel subsystems
 	  around, being created in the 2.0 kernel days, and was one of
 	  the first things added to drivers/staging/ when that was
 	  created over 15 years ago.  It should have been moved out of
 	  staging a long time ago, it's well maintained and used by
 	  loads of different devices in the real world every day.  Nice
 	  to see this finally happen.
 	- so many tiny coding style cleanups it's not funny.  Perfect
 	  storm of at least 2 different intern project application
 	  deadlines combined to provide a huge number of new
 	  contributions in this area from people learning how to do
 	  kernel development.  Great job to everyone involved here.
 
 There's also the normal updates for IIO drivers with new IIO drivers and
 updates all over that subsystem.
 
 All of these have been in linux-next for a while with no reported
 issues.

Commit 855b35ea96c4 ("usb: common: move function's kerneldoc next to its
definition") moved the USB common function documentation out of the
linux/usb/ch9.h header file into drivers/usb/common/common.c and
drivers/usb/common/debug.c, which causes the following 'make htmldocs'
build warning:

include/linux/usb/ch9.h:1: warning: no structured comments found

Fix that up by pointing the documentation at the correct location.

Hector Martin 7c566bb5e4 asm-generic/io.h: Add a non-posted variant of ioremap()
ARM64 currently defaults to posted MMIO (nGnRE), but some devices
require the use of non-posted MMIO (nGnRnE). Introduce a new ioremap()
variant to handle this case. ioremap_np() returns NULL on arches that
do not implement this variant.

sparc64 is the only architecture that needs to be touched directly,
because it includes neither of the generic io.h or iomap.h headers.

This adds the IORESOURCE_MEM_NONPOSTED flag, which maps to this
variant and marks a given resource as requiring non-posted mappings.
This is implemented in the resource system because it is a SoC-level
requirement, so existing drivers do not need special-case code to pick
this ioremap variant.

Then this is implemented in devres by introducing devm_ioremap_np(),
and making devm_ioremap_resource() automatically select this variant
when the resource has the IORESOURCE_MEM_NONPOSTED flag set.

Jason Gunthorpe 91b9969d9c vfio/mdev: Simplify driver registration
This is only done once, we don't need to generate code to initialize a
structure stored in the ELF .data segment. Fill in the three required
.driver members directly instead of copying data into them during
mdev_register_driver().

Further the to_mdev_driver() function doesn't belong in a public header,
just inline it into the two places that need it. Finally, we can now
clearly see that 'drv' derived from dev->driver cannot be NULL, firstly
because the driver core forbids it, and secondly because NULL won't pass
through the container_of(). Remove the dead code.

Jason Gunthorpe 2a3d15f270 vfio/mdev: Add missing typesafety around mdev_device
The mdev API should accept and pass a 'struct mdev_device *' in all
places, not pass a 'struct device *' and cast it internally with
to_mdev_device(). Particularly in its struct mdev_driver functions, the
whole point of a bus's struct device_driver wrapper is to provide type
safety compared to the default struct device_driver.

Further, the driver core standard is for bus drivers to expose their
device structure in their public headers that can be used with
container_of() inlines and '&foo->dev' to go between the class levels, and
'&foo->dev' to be used with dev_err/etc driver core helper functions. Move
'struct mdev_device' to mdev.h

Once done this allows moving some one instruction exported functions to
static inlines, which in turns allows removing one of the two grotesque
symbol_get()'s related to mdev in the core code.

Jason Gunthorpe 6df62c5b05 vfio: Make vfio_device_ops pass a 'struct vfio_device *' instead of 'void *'
This is the standard kernel pattern, the ops associated with a struct get
the struct pointer in for typesafety. The expected design is to use
container_of to cleanly go from the subsystem level type to the driver
level type without having any type erasure in a void *.

Jason Gunthorpe 0bfc6a4ea6 vfio: Split creation of a vfio_device into init and register ops
This makes the struct vfio_device part of the public interface so it
can be used with container_of and so forth, as is typical for a Linux
subystem.

This is the first step to bring some type-safety to the vfio interface by
allowing the replacement of 'void *' and 'struct device *' inputs with a
simple and clear 'struct vfio_device *'

For now the self-allocating vfio_add_group_dev() interface is kept so each
user can be updated as a separate patch.

The expected usage pattern is

  driver core probe() function:
     my_device = kzalloc(sizeof(*mydevice));
     vfio_init_group_dev(&my_device->vdev, dev, ops, mydevice);
     /* other driver specific prep */
     vfio_register_group_dev(&my_device->vdev);
     dev_set_drvdata(dev, my_device);

  driver core remove() function:
     my_device = dev_get_drvdata(dev);
     vfio_unregister_group_dev(&my_device->vdev);
     /* other driver specific tear down */
     kfree(my_device);

Allowing the driver to be able to use the drvdata and vfio_device to go
to/from its own data.

The pattern also makes it clear that vfio_register_group_dev() must be
last in the sequence, as once it is called the core code can immediately
start calling ops. The init/register gap is provided to allow for the
driver to do setup before ops can be called and thus avoid races.

Daniel Vetter 8613385cb2 dma-fence: Document recoverable page fault implications
Recently there was a fairly long thread about recoreable hardware page
faults, how they can deadlock, and what to do about that.

While the discussion is still fresh I figured good time to try and
document the conclusions a bit. This documentation section explains
what's the potential problem, and the remedies we've discussed,
roughly ordered from best to worst.

v2: Linus -> Linux typoe (Dave)

v3:
- Make it clear drivers only need to implement one option (Christian)
- Make it clearer that implicit sync is out the window with exclusive
  fences (Christian)
- Add the fairly theoretical option of segementing the memory (either
  statically or through dynamic checks at runtime for which piece of
  memory is managed how) and explain why it's not a great idea (Felix)

This change does a conversion of the devm_iio_dmaengine_buffer_alloc() to
devm_iio_dmaengine_buffer_setup(). This will allocate an IIO DMA buffer and
attach it to the IIO device, similar to devm_iio_triggered_buffer_setup()
(though the underlying code is different, the final logic is the same).

Since the only user of the devm_iio_dmaengine_buffer_alloc() was the
adi-axi-adc driver, this change does the replacement in a single go in the
driver.

With this change, the devm_iio_kfifo_allocate() will be made private to the

This change adds the devm_iio_kfifo_buffer_setup() helper/short-hand,
which groups the simple routine of allocating a kfifo buffers via
devm_iio_kfifo_allocate() and calling iio_device_attach_buffer().

The mode_flags parameter is required, as the IIO kfifo supports 2 modes:
INDIO_BUFFER_SOFTWARE & INDIO_BUFFER_TRIGGERED.
The setup_ops parameter is optional.

This function will be a bit more useful when needing to define multiple
buffers per IIO device.

The naming for this function has been inspired from
iio_triggered_buffer_setup() since that one does a kfifo alloc + a pollfunc
alloc. So, this should have a more familiar ring to what it is.

While the driver is still marked as maintained in MAINTAINERS, Comtrol
does not really care about this ancient driver. They are still
manufacturing serial devices, but those are controlled only by
out-of-tree drivers.

Comtrol didn't answer my pings, so this driver is apparently
unmaintained.  Aside from that, the driver was untouched for years, only

Maximilian Luz 03ee318391 platform/surface: aggregator: Make SSAM_DEFINE_SYNC_REQUEST_x define static functions
The SSAM_DEFINE_SYNC_REQUEST_x() macros are intended to reduce
boiler-plate code for SSAM request definitions by defining a wrapper
function for the specified request. The client device variants of those
macros, i.e. SSAM_DEFINE_SYNC_REQUEST_CL_x() in particular rely on the
multi-device (MD) variants, e.g.:

    #define SSAM_DEFINE_SYNC_REQUEST_CL_R(name, rtype, spec...)   \
        SSAM_DEFINE_SYNC_REQUEST_MD_R(__raw_##name, rtype, spec)  \
        int name(struct ssam_device *sdev, rtype *ret)            \
        {                                                         \
            return __raw_##name(sdev->ctrl, sdev->uid.target,     \
                                sdev->uid.instance, ret);         \
        }

This now creates the problem that it is not possible to declare the
generated functions static via

    static SSAM_DEFINE_SYNC_REQUEST_CL_R(...)

as this will only apply to the function defined by the multi-device
macro, i.e. SSAM_DEFINE_SYNC_REQUEST_MD_R(). Thus compiling with
`-Wmissing-prototypes' rightfully complains that there is a 'static'
keyword missing.

To solve this, make all SSAM_DEFINE_SYNC_REQUEST_x() macros define
static functions. Non-client-device macros are also changed for
consistency. In general, we expect those functions to be only used
locally in the respective drivers for the corresponding interfaces, so
having to define a wrapper function to be able to export this should be
the odd case out.

 maintainers, which is why this is getting larger.
 
 Included in here are:
 	- coresight driver updates
 	- habannalabs driver updates
 	- virtual acrn driver addition (proper acks from the x86
 	  maintainers)
 	- broadcom misc driver addition
 	- speakup driver updates

 	- interconnect driver udpates
 	- fsl-mc bus driver updates
 	- random driver fix
 	- some small misc driver updates (rtsx, pvpanic, etc.)
 
 All of these have been in linux-next for a while, with the only reported
 issue being a merge conflict in include/linux/mod_devicetable.h that you
 will hit in your tree due to the dfl_device_id addition from the fpga

Linus Torvalds 825d150875 cxl for 5.12
Introduce an initial driver for CXL 2.0 Type-3 Memory Devices. CXL is
 Compute Express Link which released the 2.0 specification in November.
 The Linux relevant changes in CXL 2.0 are support for an OS to
 dynamically assign address space to memory devices, support for
 switches, persistent memory, and hotplug. A Type-3 Memory Device is a
 PCI enumerated device presenting the CXL Memory Device Class Code and
 implementing the CXL.mem protocol. CXL.mem allows device to advertise
 CPU and I/O coherent memory to the system, i.e. typical "System RAM" and
 "Persistent Memory" in Linux /proc/iomem terms.
 
 In addition to the CXL.mem fast path there is an administrative command
 hardware mailbox interface for maintenance and provisioning. It is this
 command interface that is the focus of the initial driver. With this
 driver a CXL device that is mapped by the BIOS can be administered by
 Linux. Linux support for CXL PMEM and dynamic CXL address space
 management are to be implemented post v5.12.

Linus Torvalds 0e63a5c6ba It has been a relatively quiet cycle in docsland.
- As promised, the minimum Sphinx version to build the docs is now 1.7,
    and we have dropped support for Python 2 entirely.  That allowed the
    removal of a bunch of compatibility code.
 
  - A set of treewide warning fixups from Mauro that I applied after it
    became clear nobody else was going to deal with them.
 
  - The automarkup mechanism can now create cross-references from relative
    paths to RST files.
 
  - More translations, typo fixes, and warning fixes.
 
 No conflicts with any other tree as far as I know.

Ben Widawsky 583fa5e71c cxl/mem: Add basic IOCTL interface
Add a straightforward IOCTL that provides a mechanism for userspace to
query the supported memory device commands. CXL commands as they appear
to userspace are described as part of the UAPI kerneldoc. The command
list returned via this IOCTL will contain the full set of commands that
the driver supports, however, some of those commands may not be
available for use by userspace.

Memory device commands first appear in the CXL 2.0 specification. They
are submitted through a mailbox mechanism specified in the CXL 2.0
specification.

The send command allows userspace to issue mailbox commands directly to
the hardware. The list of available commands to send are the output of
the query command. The driver verifies basic properties of the command
and possibly inspect the input (or output) payload to determine whether
or not the command is allowed (or might taint the kernel).

Dan Williams b39cb1052a cxl/mem: Register CXL memX devices
Create the /sys/bus/cxl hierarchy to enumerate:

* Memory Devices (per-endpoint control devices)

* Memory Address Space Devices (platform address ranges with
  interleaving, performance, and persistence attributes)

* Memory Regions (active provisioned memory from an address space device
  that is in use as System RAM or delegated to libnvdimm as Persistent
  Memory regions).

For now, only the per-endpoint control devices are registered on the
'cxl' bus. However, going forward it will provide a mechanism to
coordinate cross-device interleave.
