struct atomisp device has struct device and struct pci_dev pointers
which are basically duplicates of each other. Drop the latter
in favour of the former.
While here, unify pdev to be pointer to struct pci_device and reindent
some (touched) lines for better readability.

There are specific ACPI and I\xB2C APIs to match device by different
parameters, such as ACPI HID, and retrieve an I\xB2C client.
Use them instead of home grown approach.
Note, it fixes a resource leak as well.

Instead of parsing GPIO for two exceptions inside the logic
which would be trying to use the GPIO, move the init code
to the routine which adds a new gmin device.
Move the notes to it too, as this helps to identify where
those two GPIO settings are used, explaining why they're
defaulting to -1 when not found.

There's only one place where a subdev can be added: when the
sensor driver registers it. Trying to do it elsewhere will
cause problems, as the detection code needs to access the
I2C bus in order to probe some things.

The media core has now a check if fi->pad is bigger than zero
or bigger than sd->entity.num_pads, if the media controller
is defined.
This causes a call to g_frame_interval to return -EINVAL.
Fix it by first cleaning up the struct.

Newer devices don't place the PMIC CLK line inside an EFI
var. Instead, those are found at the _PR0 table.
Add a parser for it, using info stored via the DSDT table.

Add support code for this driver to use ACPI power management.
Yet, at least with known devices, this won't work without
further changes.
The rationale is that the ACPI handling code checks for the _PR? tables
in order to know what is required to switch the device from power state
D0 (_PR0) up to D3COLD (_PR3).
The adev->flags.power_manageable is set to true if the device has a _PR0
table, which can be checked by calling acpi_device_power_manageable(adev).
However, this only says that the device can be set to power off mode.
At least on the DSDT tables we've seen so far, there's no _PR3 nor _PS3
(which would have a somewhat similar effect).
So, using ACPI for power management won't work, except if adding
an ACPI override logic somewhere.

The gmin_subdev_add() currently doesn't use ACPI device
power management. In order to prepare for adding support
for it, let's shift some things, placing the PM-related
stuff at the end of the probing logic.
Let's also store the current gs on a temporary var, in
order to simplify the source code.

There is one RGMII check not using the phy_interface_mode_is_rgmii()
helper. This prevents the driver from configuring the MAC properly when
using a phy-mode that is not just rgmii, e.g. rgmii-rxid. This became an
issue on sama5d3 xplained since the ksz9031 driver is hadling phy-mode
properly and the phy-mode has to be set to rgmii-rxid.

This patch disables PTP on AQC111 and AQC112 due to a known HW issue,
which can cause datapath issues.
Ideally PTP block should have been disabled via PHY provisioning, but
unfortunately many units have been shipped with enabled PTP block.
Thus, we have to work around this in the driver.

"A batch of arm64 fixes.
Although the diffstat is a bit larger than we'd usually have at this
stage, a decent amount of it is the addition of comments describing
our syscall tracing behaviour, and also a sweep across all the modular
arm64 PMU drivers to make them rebust against unloading and unbinding.
There are a couple of minor things kicking around at the moment (CPU
errata and module PLTs for very large modules), but I'm not expecting
any significant changes now for us in 5.8.
- Fix kernel text addresses for relocatable images booting using EFI
and with KASLR disabled so that they match the vmlinux ELF binary.
- Fix unloading and unbinding of PMU driver modules.
- Fix generic mmiowb() when writeX() is called from preemptible
context (reported by the riscv folks).
- Fix ptrace hardware single-step interactions with signal handlers,
system calls and reverse debugging.
- Fix reporting of 64-bit x0 register for 32-bit tasks via
'perf_regs'.

The Hardware Filter Block RAM may not be preserved when the GENET
block is reset during a deep sleep, so it is not sufficient to
only backup and restore the enables.
This commit clears out the HFB block and reprograms the rxnfc
rules when the system resumes from a suspended state. To support
this the bcmgenet_hfb_create_rxnfc_filter() function is modified
to access the register space directly so that it can't fail due
to memory allocation issues.

The vfio_pci_release call will free and clear the error and request
eventfd ctx while these ctx could be in use at the same time in the
function like vfio_pci_request, and it's expected to protect them under
the vdev->igate mutex, which is missing in vfio_pci_release.
This issue is introduced since commit 1518ac272e78 ("vfio/pci: fix memory
leaks of eventfd ctx"),and since commit 5c5866c593bb ("vfio/pci: Clear
error and request eventfd ctx after releasing"), it's very easily to
trigger the kernel panic like this:

When the extra HPD polling in sun4i_hdmi was removed, the result of

Fix this by inverting the check.

This tag contains the following fixes for 5.8-rc4/5:
- Prevent user from using command WREG_BULK in PCI DMA channel. The command
won't be parsed correctly by the driver and will cause unknown behavior.
As the user doesn't need to use that command in that channel, its better
to just prevent it completely.
- Change the interface of the clock gating debugfs property from true/false
to bitmask with bit per engine. This will allow the user to debug the
ASIC while disabling the clock gating feature with fine-grain
granularity.
- Increase message-to-ASIC-CPU timeout to 4s (from 100ms/1s). The ASIC CPU
might respond sometimes after a large delay due to slow external
interfaces (such as temperature sensors) and that will result in a driver
timeout which will lead to ASIC reset.
* tag 'misc-habanalabs-fixes-2020-07-10' of git://people.freedesktop.org/~gabbayo/linux:
habanalabs: set 4s timeout for message to device CPU
habanalabs: set clock gating per engine

Forcefully unbinding PMU drivers during perf sampling will lead to
a kernel panic, because the perf upper-layer framework call a NULL
pointer in this situation.
To solve this issue, "suppress_bind_attrs" should be set to true, so
that bind/unbind can be disabled via sysfs and prevent unbinding PMU
drivers during perf sampling.

Pull drm fixes from Dave Airlie:
"Weekly fixes pull, big bigger than I'd normally like, but they are
fairly scattered and small individually.
The vmwgfx one is a black screen regression, otherwise the largest is
an MST encoder fix for amdgpu which results in a WARN in some cases,
and a scattering of i915 fixes.
I'm tracking two regressions at the moment that hopefully we get
nailed down this week for rc7.
dma-buf:
- sleeping atomic fix
amdgpu:
- Fix a race condition with KIQ
- Preemption fix
- Fix handling of fake MST encoders
- OLED panel fix
- Handle allocation failure in stream construction
- Renoir SMC fix

i915:
- FBC w/a stride fix
- Fix use-after-free fix on module reload
- Ignore irq enabling on the virtual engines to fix device sleep
- Use GTT when saving/restoring engine GPR
- Fix selftest sort function

If a regmap has "fast_io" set then its lock function uses a spinlock.
That doesn't work so well with the functions:
* regmap_cache_only_write_file()
* regmap_cache_bypass_write_file()
Both of the above functions have the pattern:
1. Lock the regmap.
2. Call:
debugfs_write_file_bool()
copy_from_user()
__might_fault()
__might_sleep()
Let's reorder things a bit so that we do all of our sleepable
functions before we grab the lock.

Make sure we never time stamp tx packets when hardware time stamping

ourselves. In addition, disable our own hardware time stamping in this
