In the process of switching USB config from rndis to other config,
if the hardware does not support the ->pullup callback, or the
hardware encounters a low probability fault, both of them may cause
the ->pullup callback to fail, which will then cause a system panic
(use after free).
The gadget drivers sometimes need to be unloaded regardless of the
hardware's behavior.

Currently this driver triggers extcon and typec state update in its
probe function, to read out current state reported by the chip and
report the correct state to upper layers. This synchronization is
performed correctly, but only in case the chip indicates a pending
interrupt in reg09 register.
This fails to cover the situation where all interrupts reported by
the chip were already handled by Linux before reboot, then the system
rebooted, and then Linux starts again. In this case, the TUSB320 no
longer reports any interrupts in reg09, and the state update does not
perform any update as it depends on that interrupt indication.
Fix this by turning tusb320_irq_handler() into a thin wrapper around
tusb320_state_update_handler(), where the later now contains the bulk
of the code of tusb320_irq_handler(), but adds new function parameter
"force_update". The "force_update" parameter can be used by the probe
function to assure that the state synchronization is always performed,
independent of the interrupt indicated in reg09. The interrupt handler
tusb320_irq_handler() callback uses force_update=false to avoid state
updates on potential spurious interrupts and retain current behavior.

Probe for omap2430 glue layer is now broken for interrupt resources in
all cases.
Commit 2390710647 ("partially Revert "usb: musb: Set the DT node on the
child device"") broke probing for SoCs using ti-sysc interconnect target
module as the dt node is not found.
Commit a1a2b7125e ("of/platform: Drop static setup of IRQ resource from
DT core") caused omap3 to fail with error "-ENXIO: IRQ mc not found" as
the IRQ resources are no longer automatically populated from devicetree.
Let's fix the issues by calling device_set_of_node_from_dev() only if the
SoC has been updated to probe with ti-sysc. And for legacy SoCs, let's
populate the resources manually as needed.
Note that once we have updated the SoCs to probe with proper devicetree
data in all cases, this is no longer needed. But doing that requires
patching both devicetree and SoC code, so let's fix the probe issues first.

This is a bit of special case, so mimic the Kconfig incantations
from DWC3: let the subdrivers for host or peripheral depend
on the host or gadget support being =y or the same as the
FOTG210 core itself.
This should ensure that either:
- The host (CONFIG_USB) or gadget (CONFIG_GADGET) is compiled
in and then the FOTG210 can be either module or compiled
in.
- The host or gadget is modular, and then the FOTG210 module
must be a module too, or we cannot resolve the symbols
at link time.

The flag that tells the event to call its triggers after reading the event
is set for eprobes after the eprobe is enabled. This leads to a race where
the eprobe may be triggered at the beginning of the event where the record
information is NULL. The eprobe then dereferences the NULL record causing
a NULL kernel pointer bug.
Test for a NULL record to keep this from happening.

SRS cap is the hardware cap telling if the hardware IOMMU can support
requests seeking supervisor privilege or not. SRE bit in scalable-mode
PASID table entry is treated as Reserved(0) for implementation not
supporting SRS cap.
Checking SRS cap before setting SRE bit can avoid the non-recoverable
fault of "Non-zero reserved field set in PASID Table Entry" caused by
setting SRE bit while there is no SRS cap support. The fault messages
look like below:
DMAR: DRHD: handling fault status reg 2
DMAR: [DMA Read NO_PASID] Request device [00:0d.0] fault addr 0x1154e1000
[fault reason 0x5a]

The A/D bits are preseted for IOVA over first level(FL) usage for both
kernel DMA (i.e, domain typs is IOMMU_DOMAIN_DMA) and user space DMA
usage (i.e., domain type is IOMMU_DOMAIN_UNMANAGED).
Presetting A bit in FL requires to preset the bit in every related paging
entries, including the non-leaf ones. Otherwise, hardware may treat this
as an error. For example, in a case of ECAP_REG.SMPWC==0, DMA faults might
occur with below DMAR fault messages (wrapped for line length) dumped.
DMAR: DRHD: handling fault status reg 2
DMAR: [DMA Read NO_PASID] Request device [aa:00.0] fault addr 0x10c3a6000

CONFIG_FUNCTION_GRAPH_TRACER is not enabled.

- Fix deadlock in discontiguous saved segments (DCSS) block device
driver. When adding a disk and scanning partitions the scan would
not break out early without a missed flag.
- Avoid using global register variable for current_stack_pointer

bug a broken code is generated, which leads to stack corruptions.
