feb5dc3de0 Documentation: KVM: Document KVM_GUESTDBG_USE_HW control flag for arm64
Commit 21b6f32f94 ("KVM: arm64: guest debug, define API headers") added
the arm64 KVM_GUESTDBG_USE_HW flag for the KVM_SET_GUEST_DEBUG ioctl and
commit 834bf88726 ("KVM: arm64: enable KVM_CAP_SET_GUEST_DEBUG")
documented and implemented the flag functionality. Since its introduction,
at no point was the flag known by any name other than KVM_GUESTDBG_USE_HW
for the arm64 architecture, so refer to it as such in the documentation.

3bf725699b KVM: arm64: Add support for the KVM PTP service
Implement the hypervisor side of the KVM PTP interface.

The service offers wall time and cycle count from host to guest.
The caller must specify whether they want the host's view of
either the virtual or physical counter.

Qualcomm ARM64 DT updates for 5.13

This extends the initial SM8350 description merged in v5.12 with
CPUfreq, SMMU, UFS, RPMHPD, SPMI, USB and remoteproc support. It adds
initial PMIC definitions for the 6 PMICs found on the MTP and it
introduces the new SM8350 Hardware Development Kit (HDK).

SC7180 is further polished, the DisplayPort portion of the QMP phy is
defined and several new SKUs of the Trogdor devices are introduced.

The new SC7280 platform is introduced, with RPMH, RPMHPD, RPMCC, SPMI,
CPU idle, SMMU and watchdog defined.

SDM845 gains the camera related nodes and some cleanups.

For SM8250 it brings some cleanups and migrates SPI0 to use GPIO for
chip select.

a48849e235 printk: clarify the documentation for plain pointer printing
We have several modifiers for plain pointers (%p, %px and %pK) and now
also the no_hash_pointers boot parameter. The documentation should help
to choose which variant to use. Importantly, we should discourage %px
in favor of %p (with the new boot parameter when debugging), and stress
that %pK should be only used for procfs and similar files, not dmesg
buffer. This patch clarifies the documentation in that regard.

2nd set of IIO features, cleanups etc for 5.13

I was running.

A few of these are fixes for major rework earlier in cycle.
Bulk of patches are the ad7150 pre graduation cleanup, some link
fixes in maintainers and set using the new IRQF_NO_AUTOEN flag.

support (one patch only from Barry Song)

  - Tidy up some pointless type conversion in string formatting and odd
    indentation.

ee590106c3 dt-bindings: mtd: Add a property to declare secure regions in NAND chips
On a typical end product, a vendor may choose to secure some regions in
the NAND memory which are supposed to stay intact between FW upgrades.
The access to those regions will be blocked by a secure element like
Trustzone. So the normal world software like Linux kernel should not
touch these regions (including reading).

So let's add a property for declaring such secure regions so that the
drivers can skip touching them.

Binding covering the ad7150, ad7151 and ad7156 capacitance to digital
convertors.  The only difference between these is how many channels they
have (1 or 2)

Whilst it is clearly necessary to provide power to the part, we don't
need to know the voltage or anything so if it is always on, there should
be no need to have it specified in the binding.

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 *.

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.

7d33004d24 pata_legacy: Add `probe_mask' parameter like with ide-generic
Carry the `probe_mask' parameter over from ide-generic to pata_legacy so
that there is a way to prevent random poking at ISA port I/O locations
in attempt to discover adapter option cards with libata like with the
old IDE driver.  By default all enabled locations are tried, however it
may interfere with a different kind of hardware responding there.

For example with a plain (E)ISA system the driver tries all the six
possible locations:

scsi host0: pata_legacy
ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14
ata1.00: ATA-4: ST310211A, 3.54, max UDMA/100
ata1.00: 19541088 sectors, multi 16: LBA
ata1.00: configured for PIO
scsi 0:0:0:0: Direct-Access     ATA      ST310211A        3.54 PQ: 0 ANSI: 5

scsi host1: pata_legacy
ata2: PATA max PIO4 cmd 0x170 ctl 0x376 irq 15
scsi host1: pata_legacy
ata3: PATA max PIO4 cmd 0x1e8 ctl 0x3ee irq 11
scsi host1: pata_legacy
ata4: PATA max PIO4 cmd 0x168 ctl 0x36e irq 10

ata5: PATA max PIO4 cmd 0x1e0 ctl 0x3e6 irq 8
scsi host1: pata_legacy
ata6: PATA max PIO4 cmd 0x160 ctl 0x366 irq 12

however giving the kernel "pata_legacy.probe_mask=21" makes it try every
other location only:

scsi host0: pata_legacy
ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14

- `probe_all' affects tertiary and further port ranges rather than all,

dd0008beef media: dt-bindings: media: mtk-vcodec: Separating mtk vcodec encoder node
Updates binding document since the avc and vp8 hardware encoder in
MT8173 are now separated. Separate "mediatek,mt8173-vcodec-enc" to
"mediatek,mt8173-vcodec-enc-vp8" and "mediatek,mt8173-vcodec-enc".

This patch is not a compatible change, but we must do this modifaction
because MediaTek IOMMU add the device_link between the smi-larb
device and venc_device, if the venc device call the pm_runtime_get_sync,
the smi-larb's pm_runtime_get_sync also be called automatically.

There is a bit of backward compatibility for avc encoder, the avc
encoder device node still has compatible "mediatek,mt8173-vcodec-enc".
