Without the .owner field, the module can be unloaded while /dev/vmclock0

The settings for all GPIOs are locked by default in bcm_kona_gpio_reset.
The settings for a GPIO are unlocked when requesting it as a GPIO, but
not when requesting it as an interrupt, causing the IRQ settings to not
get applied.
Fix this by making sure to unlock the right bits when an IRQ is requested.
To avoid a situation where an IRQ being released causes a lock despite
the same GPIO being used by a GPIO request or vice versa, add an unlock
counter and only lock if it reaches 0.

The GPIO lock/unlock functions clear/write a bit to the relevant
register for each bank. However, due to an oversight the bit that
was being written was based on the total GPIO number, not the index
of the GPIO within the relevant bank, causing it to fail for any
GPIO above 32 (thus any GPIO for banks above bank 0).
Fix lock/unlock for these banks by using the correct bit.

Look up the mode index for the astdp transmitter ship in the encoder's
atomic check and report an error if the display mode is not supported.
The lookup uses the DRM display mode instead of the driver's internal
VBIOS mode. Both are equivalent. The modesetting code later reads
the calculated index from the connector state to avoid recalculating it.

Programming the astdp transmitter chip requires a magic value for
individual modes. Inline the helper for calculating the value into
its only caller (i.e., the encoder's atomic_mode_set).
With further refactoring, the atomic check will be able to detect
invalid modes before attempting to program them.

Commit df542f669307 ("net: stmmac: Switch to zero-copy in
non-XDP RX path") makes DMA write received frame into buffer at offset
of NET_SKB_PAD and sets page pool parameters to sync from offset of
NET_SKB_PAD. But when Header Payload Split is enabled, the header is
written at offset of NET_SKB_PAD, while the payload is written at
offset of zero. Uncorrect offset parameter for the payload breaks dma
coherence [1] since both CPU and DMA touch the page buffer from offset
of zero which is not handled by the page pool sync parameter.
And in case the DMA cannot split the received frame, for example,
a large L2 frame, pp_params.max_len should grow to match the tail
of entire frame.

The iopf_queue_remove_device() helper removes a device from the per-iommu
iopf queue when PRI is disabled on the device. It responds to all
outstanding iopf's with an IOMMU_PAGE_RESP_INVALID code and detaches the
device from the queue.
However, it fails to release the group structure that represents a group
of iopf's awaiting for a response after responding to the hardware. This
can cause a memory leak if iopf_queue_remove_device() is called with
pending iopf's.
Fix it by calling iopf_free_group() after the iopf group is responded.

Commit 8c87215dd3a2 ("ata: libahci_platform: support non-consecutive
port numbers") modified ahci_platform_get_resources() to allow
identifying the ports of a controller that are defined as child nodes of
the controller node in order to support non-consecutive port numbers (as
defined by the platform device tree).
However, this commit also erroneously sets bit 0 of
hpriv->mask_port_map when the platform devices tree does not define port
child nodes, to match the fact that the temporary default number of
ports used in that case is 1 (which is also consistent with the fact
that only index 0 of hpriv->phys[] is initialized with the call to
ahci_platform_get_phy(). But doing so causes ahci_platform_init_host()
to initialize and probe only the first port, even if this function
determines that the controller has in fact multiple ports using the
capability register of the controller (through a call to
ahci_nr_ports()). This can be seen with the ahci_mvebu driver (Armada
385 SoC) with the second port declared as "dummy":
ahci-mvebu f10a8000.sata: masking port_map 0x3 -> 0x1
ahci-mvebu f10a8000.sata: AHCI vers 0001.0000, 32 command slots, 6 Gbps, platform mode

ata1: SATA max UDMA/133 mmio [mem 0xf10a8000-0xf10a9fff] port 0x100 irq 40 lpm-pol 0

Fix this issue by removing setting bit 0 of hpriv->mask_port_map when
the platform device tree does not define port child nodes.

which is default FW power profile.
Implement IVPU_TEST_MODE_D0I2_DISABLE which is used for setting
power profile boot param value to 1 which prevents NPU from entering

Use ivpu_gem_prime_import() based on drm_gem_prime_import_dev()
for importing buffers, removing optimization for same device
imports. This optimization reused the same ivpu_bo object in multiple
contexts but a single buffer can be MMU-mapped only to a single context.
Each import now creates a new instance of ivpu_bo object that shares
the same sg_table but have separate MMU mappings.

Commit 3775fc538f53 ("PM: sleep: core: Synchronize runtime PM status of
parents and children") exposed an issue related to simple_pm_bus_pm_ops
that uses pm_runtime_force_suspend() and pm_runtime_force_resume() as
bus type PM callbacks for the noirq phases of system-wide suspend and
resume.
The problem is that pm_runtime_force_suspend() does not distinguish
runtime-suspended devices from devices for which runtime PM has never
been enabled, so if it sees a device with runtime PM status set to
RPM_ACTIVE, it will assume that runtime PM is enabled for that device
and so it will attempt to suspend it with the help of its runtime PM
callbacks which may not be ready for that. As it turns out, this
causes simple_pm_bus_runtime_suspend() to crash due to a NULL pointer
dereference.
Another problem related to the above commit and simple_pm_bus_pm_ops is
that setting runtime PM status of a device handled by the latter to
RPM_ACTIVE will actually prevent it from being resumed because
pm_runtime_force_resume() only resumes devices with runtime PM status
set to RPM_SUSPENDED.
To mitigate these issues, do not allow power.set_active to propagate
beyond the parent of the device with DPM_FLAG_SMART_SUSPEND set that
will need to be resumed, which should be a sufficient stop-gap for the
time being, but they will need to be properly addressed in the future
because in general during system-wide resume it is necessary to resume
all devices in a dependency chain in which at least one device is going
to be resumed.

The driver assumed that es58x_dev->udev->serial could never be NULL.
While this is true on commercially available devices, an attacker
could spoof the device identity providing a NULL USB serial number.
That would trigger a NULL pointer dereference.
