133be0264f nl802154: export supported commands
This patch will export the supported commands by the devices
to the userspace. This will be useful to check if HardMAC
drivers can support a specific command or not.

8a9782346d ASoC: topology: Add topology core
The topology core parses the FW topology file for known block types and
instanciates any common ALSA/ASoC objects that it discovers. The core
also passes any block that is does not understand to client component
drivers for enumeration.

The core exports some APIs to client drivers in order to load and unload
firmware topology data as use case require.

Currently the core deals with the following object types :-

 o kcontrols. This includes TLV, enumerated and bytes controls.
 o DAPM widgets. All types with any associated kcontrol.
 o DAPM graph.
 o FE PCM. FE PCM capabilities and configuration can be defined.
 o BE DAI Link. BE DAI link capabilities and configuration can be defined.
 o Codec <-> codec style links capabilities and configuration.

ce5c5d554d dax: expose __dax_fault for filesystems with locking constraints
Some filesystems cannot call dax_fault() directly because they have
different locking and/or allocation constraints in the page fault IO
path. To handle this, we need to follow the same model as the
generic block_page_mkwrite code, where the internals are exposed via
__block_page_mkwrite() so that filesystems can wrap the correct
locking and operations around the outside. 

This is loosely based on a patch originally from Matthew Willcox.
Unlike the original patch, it does not change ext4 code, error
returns or unwritten extent conversion handling.  It also adds a
__dax_mkwrite() wrapper for .page_mkwrite implementations to do the
right thing, too.

e842f29039 dax: don't abuse get_block mapping for endio callbacks
dax_fault() currently relies on the get_block callback to attach an
io completion callback to the mapping buffer head so that it can
run unwritten extent conversion after zeroing allocated blocks.

Instead of this hack, pass the conversion callback directly into
dax_fault() similar to the get_block callback. When the filesystem
allocates unwritten extents, it will set the buffer_unwritten()
flag, and hence the dax_fault code can call the completion function
in the contexts where it is necessary without overloading the
mapping buffer head.

Note: The changes to ext4 to use this interface are suspect at best.
In fact, the way ext4 did this end_io assignment in the first place
looks suspect because it only set a completion callback when there
wasn't already some other write() call taking place on the same
inode. The ext4 end_io code looks rather intricate and fragile with
all it's reference counting and passing to different contexts for
modification via inode private pointers that aren't protected by
locks...

One more round of drm-misc, again mostly atomic. Big thing is the
userspace blob code from Daniel Stone, with support for the mode_id blob
now added to the atomic ioctl. Finally we can do atomic modesets!

Note that the atomic ioctl is still behind the module knob since the
weston patches aren't quite ready yet imo - they lack TEST_ONLY support,
which is a fairly crucial bit of the atomic api. But besides that I think
it's all good to go. That's also why we didn't bother to hide the new blob
ioctls behind the knob, that part won't need to change. And if weston
patches get in shape in time we could throw the "atomic by default patch"
on top for 4.2.

 o kcontrols including TLV controls.
 o DAPM widgets and graph elements
 o Vendor bespoke objects.
 o Coefficient data
 o FE PCM capabilities and config.
 o BE link capabilities and config.
 o Codec <-> codec link capabilities and config.
 o Topology object manifest.

The file format is simple and divided into blocks for each object type and
each block has a header that defines it's size and type. Blocks can be in
any order of type and can either all be in a single file or spread across
more than one file. Blocks also have a group identifier ID so that they can
be loaded and unloaded by ID.

dc5698e80c Add virtio gpu driver.
This patch adds a kms driver for the virtio gpu.  The xorg modesetting
driver can handle the device just fine, the framebuffer for fbcon is
there too.

Qemu patches for the host side are under review currently.

The pci version of the device comes in two variants: with and without
vga compatibility.  The former has a extra memory bar for the vga
framebuffer, the later is a pure virtio device.  The only concern for
this driver is that in the virtio-vga case we have to kick out the
firmware framebuffer.

Initial revision has only 2d support, 3d (virgl) support requires
some more work on the qemu side and will be added later.

The breakages were triggering in places where x86 builds relied
on vmalloc() facilities but did not include <linux/vmalloc.h>
explicitly and relied on the implicit inclusion via <asm/io.h>.

Also add:

  - <linux/init.h> to <linux/io.h>
  - <asm/pgtable_types> to <asm/io.h>

... which were two other implicit header file dependencies.

cc9866eb94 video: fbdev: tdfxfb: use arch_phys_wc_add() and ioremap_wc()
This driver uses the same area for MTRR as for the ioremap().
Convert the driver from using the x86 specific MTRR code to
the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add()
will avoid MTRR if write-combining is available, in order to
take advantage of that also ensure the ioremap'd area is requested
as write-combining.

There are a few motivations for this:

a) Take advantage of PAT when available

b) Help bury MTRR code away, MTRR is architecture specific and on
   x86 its replaced by PAT

c) Help with the goal of eventually using _PAGE_CACHE_UC over
   _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
   de33c442e titled "x86 PAT: fix performance drop for glx,
   use UC minus for ioremap(), ioremap_nocache() and
   pci_mmap_page_range()")

The conversion done is expressed by the following Coccinelle
SmPL patch, it additionally required manual intervention to
address all the #ifdery and removal of redundant things which
arch_phys_wc_add() already addresses such as verbose message
about when MTRR fails and doing nothing when we didn't get
an MTRR.

aef11009c4 drm/amdkfd: add H/W debugger IOCTL set definitions
This patch adds four new IOCTLs to amdkfd. These IOCTLs expose a H/W
debugger functionality to the userspace.

The IOCTLs are:

- AMDKFD_IOC_DBG_REGISTER:

The purpose of this IOCTL is to notify amdkfd that a process wants to use
GPU debugging facilities on itself only.
It is expected that this IOCTL would be called before any other H/W
debugger requests are sent to amdkfd and for each GPU where the H/W
debugging needs to be enabled. The use of this IOCTL ensures that only
one instance of a debugger is active in the system.

- AMDKFD_IOC_DBG_UNREGISTER:

This IOCTL detaches the debugger/debugged process from the H/W
Debug which was established by the AMDKFD_IOC_DBG_REGISTER IOCTL.

- AMDKFD_IOC_DBG_ADDRESS_WATCH:

This IOCTL allows to set different watchpoints with various conditions as
indicated by the IOCTL's arguments. The available number of watchpoints
is retrieved from topology. This operation is confined to the current
debugged process, which was registered through AMDKFD_IOC_DBG_REGISTER.

- AMDKFD_IOC_DBG_WAVE_CONTROL:

This IOCTL allows to control a wavefront as indicated by the IOCTL's
arguments. For example, you can halt/resume or kill either a
single wavefront or a set of wavefronts. This operation is confined to
the current debugged process, which was registered through
AMDKFD_IOC_DBG_REGISTER.

Because the arguments for the address watch IOCTL and wave control IOCTL
are dynamic, meaning that they could vary in size, the userspace passes a
pointer to a structure (in userspace) that contains the value of the
arguments. The kernel driver is responsible to parse this structure and
validate its contents.

v2: change void* to uint64_t inside ioctl arguments

00465f4c84 Update extcon for v4.2
This patchset include the huge update of extcon core and add the new one extcon
 driver and fix minor isseu of extcon drivers.
 
 Detailed description for patchset:
 1. Update the extcon core.
 - Modify the extcon device name on sysfs from device name name to 'extcon[X]'
 as following because if same extcon device are included in H/W development board,
 the one of the two device driver might be failed on the probe().
 : /sys/class/extcon/[device name] -> /sys/class/extcon/extcon[X]
 
 - Use the unique id for external connectors instead of legacy string name.
 Previously, extcon used the string name to identify the type of external
 connectors. This way have the many potential issues. So, extcon core define the
 unique id for each external connectors as following:
 
 	enum extcon {
 		EXTCON_NONE             = 0x0,
 
 		/* USB external connector */
 		EXTCON_USB              = 0x1,
 		EXTCON_USB_HOST		= 0x2,
 
 		/* Charger external connector */
 		EXTCON_TA		= 0x10,
 		EXTCON_FAST_CHARGER	= 0x11,
 		EXTCON_SLOW_CHARGER	= 0x12,
 		EXTCON_CHARGE_DOWNSTREAM = 0x13,
 
 		/* Audio and video external connector */
 		EXTCON_LINE_IN		= 0x20,
 		EXTCON_LINE_OUT		= 0x21,
 		EXTCON_MICROPHONE	= 0x22,
 		EXTCON_HEADPHONE	= 0x23,
 		...
 	};
 
 - Update tye prototype of extcon_register_notifier() by using the unique id
 (enum extcon) of external connectors.
 
 - Add extcon_get_edev_name() API to get the name of extcon device on extcon
 client driver because the name is included in 'struct extcon_dev' and 'struct
 extcon_dev' should be handled in only drivers/extcon directory. So. if extcon
 client need the name of extcon device, they could use this function.
 
 - Unify the jig/dock and MHL-TA cable name on extcon driver.
 : JIG-{USB-ON|USB-OFF|UART-ON|UART-OFF} -> JIG
 : Dock-{Smart|Desk|Audio|Card} -> DOCK
 : MHL-TA -> TA
 
 - Use the capital letter for the name of all external connectors.
 - Remove the optional print_name() function pointer from struct extcon_dev to
 maintain the consistent name of extcon device.
 
 2. Add the new extcon-axp288.c extcon driver.
 - The extcon-axp288.c driver support for AXP288 PMIC which has the BC1.2
 charger detection capability. So this extcon driver can detect the
 EXTCON_SLOW_CHARGER, EXTCON_CHARGE_DOWNSTREAM and EXTCON_FAST_CHARGER.
 
 3. Update the extcon-arizona.c driver.
 - Add support for selective detection mode when headphone detection.
 - Apply HP clamps for WM8280
 
 4. Clean-up the extcon core and drivers.
 - Add manufactor information of each extcon device.
 - Fix checkpatch warning and minor coding style on extcon.c.c
 - Fix build break if GPIOLIB is not enabled on extcon-usb-gpiio.c.
 - Set the direction of gpio when calling devm_gpiod_get() on extcon-usb-gpio.c

6f7f0b3df6 cxl: Add AFU virtual PHB and kernel API
This patch does two things.

Firstly it presents the Accelerator Function Unit (AFUs) behind the POWER
Service Layer (PSL) as PCI devices on a virtual PCI Host Bridge (vPHB).  This
in in addition to the PSL being a PCI device itself.

As part of the Coherent Accelerator Interface Architecture (CAIA) AFUs can
provide an AFU configuration.  This AFU configuration recored is architected to
be the same as a PCI config space.

This patch sets discovers the AFU configuration records, provides AFU config
space read/write functions to these configuration records.  It then enumerates
the PCI bus.  It also hooks in PCI ops where appropriate.  It also destroys the
vPHB when the physical card is removed.

Secondly, it add an in kernel API for AFU to use CXL.  AFUs must present a
driver that firstly binds as a PCI device.  This PCI device can then be using
to do CXL specific operations (that can't sit in the PCI ops) using this API.
