Switch the driver from legacy gpio API that is deprecated to the newer
gpiod API that respects line polarities described in ACPI/DT.
Note that because existing DTSes specify incorrect polarity of reset
lines (active high) and GPU drivers have adopted to this, we follow
the suit and use inverted values when controlling reset lines.

Only a single out of three devices need a PWM, so from driver it's
optional. Moreover it's a single driver in the entire kernel that
currently selects PWM. Unfortunately this selection is a root cause
of the circular dependencies when we want to enable optional PWM
for some other drivers that select GPIOLIB.

It seems we can have one or more framebuffers that are still pinned when
suspending lmem, in such a case we end up creating a shmem backup
object, instead of evicting the object directly, but this will skip
copying the CCS aux state, since we don't allocate the extra storage for
the CCS pages as part of the ttm_tt construction. Since we can already
deal with pinned objects just fine, it doesn't seem too nasty to just
extend to support dealing with the CCS aux state, if the object is a
pinned framebuffer. This fixes display corruption (like in gnome-shell)
seen on DG2 when returning from suspend.

In the case of lmem -> lmem transfers, which is currently only possible
with small-bar systems, we need to ensure we copy the CCS aux state

Currently, the max_loop commandline argument can be used to specify how
many loop block devices are created at init time. If it is not
specified on the commandline, CONFIG_BLK_DEV_LOOP_MIN_COUNT loop block
devices will be created.
The max_loop commandline argument can be used to override the value of
CONFIG_BLK_DEV_LOOP_MIN_COUNT. However, when max_loop is set to 0
through the commandline, the current logic treats it as if it had not
been set, and creates CONFIG_BLK_DEV_LOOP_MIN_COUNT devices anyway.
Fix this by starting max_loop off as set to CONFIG_BLK_DEV_LOOP_MIN_COUNT.
This preserves the intended behavior of creating
CONFIG_BLK_DEV_LOOP_MIN_COUNT loop block devices if the max_loop
commandline parameter is not specified, and allowing max_loop to
be respected for all values, including 0.
This allows environments that can create all of their required loop
block devices on demand to not have to unnecessarily preallocate loop
block devices.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Squash portdrv_{core,pci}.c into portdrv.c to ease maintenance and
make more things static.
- Make portdrv bind to Switch Ports that have AER. Previously, if
these Ports lacked MSI/MSI-X, portdrv failed to bind, which meant
the Ports couldn't be suspended to low-power states. AER on these
Ports doesn't use interrupts, and the AER driver doesn't need to
claim them.
- Assign PCI domain IDs using ida_alloc(), which makes host bridge
add/remove work better.
Resource management:
- To work better with recent BIOSes that use EfiMemoryMappedIO for
PCI host bridge apertures, remove those regions from the E820 map
(E820 entries normally prevent us from allocating BARs). In v5.19,
we added some quirks to disable E820 checking, but that's not very
maintainable. EfiMemoryMappedIO means the OS needs to map the
region for use by EFI runtime services; it shouldn't prevent OS
from using it.
PCIe native device hotplug:
- Build pciehp by default if USB4 is enabled, since Thunderbolt/USB4
PCIe tunneling depends on native PCIe hotplug.
- Enable Command Completed Interrupt only if supported to avoid user
confusion from lspci output that says this is enabled but not
supported.
- Prevent pciehp from binding to Switch Upstream Ports; this happened
because of interaction with acpiphp and caused devices below the
Upstream Port to disappear.
Power management:
- Convert AGP drivers to generic power management. We hope to remove
legacy power management from the PCI core eventually.
Virtualization:
- Fix pci_device_is_present(), which previously always returned
"false" for VFs, causing virtio hangs when unbinding the driver.
Miscellaneous:
- Convert drivers to gpiod API to prepare for dropping some legacy
code.
- Fix DOE fencepost error for the maximum data object length.
Baikal-T1 PCIe controller driver:
- Add driver and DT bindings.
Broadcom STB PCIe controller driver:
- Enable Multi-MSI.
- Delay 100ms after PERST# deassert to allow power and clocks to
stabilize.
- Configure Read Completion Boundary to 64 bytes.
Freescale i.MX6 PCIe controller driver:
- Initialize PHY before deasserting core reset to fix a regression in
v6.0 on boards where the PHY provides the reference.
- Fix imx6sx and imx8mq clock names in DT schema.
Intel VMD host bridge driver:
- Fix Secondary Bus Reset on VMD bridges, which allows reset of NVMe
SSDs in VT-d pass-through scenarios.
- Disable MSI remapping, which gets re-enabled by firmware during
suspend/resume.
MediaTek PCIe Gen3 controller driver:
- Add MT7986 and MT8195 support.
Qualcomm PCIe controller driver:
- Add SC8280XP/SA8540P basic interconnect support.
Rockchip DesignWare PCIe controller driver:
- Base DT schema on common Synopsys schema.
Synopsys DesignWare PCIe core:
- Collect DT items shared between Root Port and Endpoint (PERST GPIO,
PHY info, clocks, resets, link speed, number of lanes, number of
iATU windows, interrupt info, etc) to snps,dw-pcie-common.yaml.
- Add dma-ranges support for Root Ports and Endpoints.
- Consolidate DT resource retrieval for "dbi", "dbi2", "atu", etc. to
reduce code duplication.
- Add generic names for clocks and resets to encourage more
consistent naming across drivers using DesignWare IP.
- Stop advertising PTM Responder role for Endpoints, which aren't
allowed to be responders.
TI J721E PCIe driver:
- Add j721s2 host mode ID to DT schema.
- Add interrupt properties to DT schema.
Toshiba Visconti PCIe controller driver:
- Fix interrupts array max constraints in DT schema"

Pull iommufd implementation from Jason Gunthorpe:
"iommufd is the user API to control the IOMMU subsystem as it relates
to managing IO page tables that point at user space memory.
It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO
container) which is the VFIO specific interface for a similar idea.
We see a broad need for extended features, some being highly IOMMU
device specific:
- Binding iommu_domain's to PASID/SSID
- Userspace IO page tables, for ARM, x86 and S390
- Kernel bypassed invalidation of user page tables
- Re-use of the KVM page table in the IOMMU
- Dirty page tracking in the IOMMU
- Runtime Increase/Decrease of IOPTE size
- PRI support with faults resolved in userspace
Many of these HW features exist to support VM use cases - for instance
the combination of PASID, PRI and Userspace IO Page Tables allows an
implementation of DMA Shared Virtual Addressing (vSVA) within a guest.
Dirty tracking enables VM live migration with SRIOV devices and PASID
support allow creating "scalable IOV" devices, among other things.
As these features are fundamental to a VM platform they need to be
uniformly exposed to all the driver families that do DMA into VMs,
which is currently VFIO and VDPA"

Instead of reserving a VMID for a single process allow that many
processes use the reserved ID. This allows for proper isolation
between the processes.

This is completely pointless since the VMID always stays allocated until
the VM is idle.

This should probably not access job->vm and also emit the SPM switch
under the conditional execute.

Bas pointed out that this isn't working as expected and could cause
crashes. Fix the handling by storing the marker that a switch is needed
inside the job instead.

When buffers are freed during suspend there is no guarantee that
they can be re-allocated during resume.
The PSP subsystem seems to be quite buggy regarding this, so add
a WARN_ON() to point out those bugs.

A remove callback just returning 0 is equivalent to no remove callback
at all. So drop the useless function.
