This driver uses its own spinlock in interrupt routines while the
generic GPIO chip callbacks use a separate one. This is, of course, racy
so use the fact that the lock in generic GPIO chip is also a spinlock and
convert the interrupt handling functions in this module to using the
provided generic GPIO chip locking API.

The conversion to using the modernized generic GPIO chip API was
incomplete without also converting the direct calls to write/read_reg()

While these flags are private within drivers/gpio/, when looking at the
code, it's not really clear they are GPIO-specific. Since these are GPIO
descriptor flags, prepend their names with a common "GPIOD" prefix.
While at it: update the flags' docs: make spelling consistent, correct
outdated information, etc.

wg_cpumask_choose_online()
The function gets number of online CPUS, and uses it to search for
Nth cpu in cpu_online_mask.
If id == num_online_cpus() - 1, and one CPU gets offlined between
calling num_online_cpus() -> cpumask_nth(), there's a chance for
cpumask_nth() to find nothing and return >= nr_cpu_ids.
The caller code in __queue_work() tries to avoid that by checking the
returned CPU against WORK_CPU_UNBOUND, which is NR_CPUS. It's not the
same as '>= nr_cpu_ids'. On a typical Ubuntu desktop, NR_CPUS is 8192,
while nr_cpu_ids is the actual number of possible CPUs, say 8.
The non-existing cpu may later be passed to rcu_dereference() and
corrupt the logic. Fix it by switching from 'if' to 'while'.

Starting with commit c50e7475961c ("dpaa2-switch: Fix error checking in
dpaa2_switch_seed_bp()"), the probing of a second DPSW object errors out
like below.
fsl_dpaa2_switch dpsw.1: fsl_mc_driver_probe failed: -12
fsl_dpaa2_switch dpsw.1: probe with driver fsl_dpaa2_switch failed with error -12
The aforementioned commit brought to the surface the fact that seeding
buffers into the buffer pool destined for control traffic is not
successful and an access violation recoverable error can be seen in the
MC firmware log:
[E, qbman_rec_isr:391, QBMAN] QBMAN recoverable event 0x1000000
This happens because the driver incorrectly used the ID of the DPBP
object instead of the hardware buffer pool ID when trying to release
buffers into it.
This is because any DPSW object uses two buffer pools, one managed by
the Linux driver and destined for control traffic packet buffers and the
other one managed by the MC firmware and destined only for offloaded
traffic. And since the buffer pool managed by the MC firmware does not
have an external facing DPBP equivalent, any subsequent DPBP objects
created after the first DPSW will have a DPBP id different to the
underlying hardware buffer ID.
The issue was not caught earlier because these two numbers can be
identical when all DPBP objects are created before the DPSW objects are.
This is the case when the DPL file is used to describe the entire DPAA2
object layout and objects are created at boot time and it's also true
for the first DPSW being created dynamically using ls-addsw.
Fix this by using the buffer pool ID instead of the DPBP id when
releasing buffers into the pool.

When upstreaming the Gen4 PTP support for R-Car S4 the possibility for
different memory layouts on other Gen4 SoCs was build in. It turns out
this is not needed and instead needlessly makes the driver harder to
read, remove the support code that would have allowed different memory
layouts.
This change only deals with the public functions used by other drivers,
follow up work will clean up the rcar_gen4_ptp internals.

When 8139too is probing and 8139TOO_PIO=y it will call pci_iomap_range()
and from there __pci_ioport_map() for the PCI IO space.
If HAS_IOPORT_MAP=n and NO_GENERIC_PCI_IOPORT_MAP=n, like it is on my
m68k config, __pci_ioport_map() becomes NULL, pci_iomap_range() will
always fail and the driver will complain it couldn't map the PIO space
and return an error.
NO_IOPORT_MAP seems to cover the case where what 8139too is trying
to do cannot ever work so make 8139TOO_PIO depend on being it false
and avoid creating an unusable driver.

The bm_work work item should be scheduled after holding fw_card reference
counting. At a commit 25feb1a96e21 ("firewire: core: use cleanup function
in bm_work"), I misinterpreted it as fw_card spinlock and inserted
lockdep_assert_hold() wrongly.
This commit removes the useless line.

Introduce new DMA mapping functions dma_map_phys() and dma_unmap_phys()
that operate directly on physical addresses instead of page+offset
parameters. This provides a more efficient interface for drivers that
already have physical addresses available.
The new functions are implemented as the primary mapping layer, with
the existing dma_map_page_attrs()/dma_map_resource() and
dma_unmap_page_attrs()/dma_unmap_resource() functions converted to simple
wrappers around the phys-based implementations.
In case dma_map_page_attrs(), the struct page is converted to physical
address with help of page_to_phys() function and dma_map_resource()
provides physical address as is together with addition of DMA_ATTR_MMIO
attribute.
The old page-based API is preserved in mapping.c to ensure that existing
code won't be affected by changing EXPORT_SYMBOL to EXPORT_SYMBOL_GPL
variant for dma_*map_phys().

Convert the KMSAN DMA handling function from page-based to physical
address-based interface.
The refactoring renames kmsan_handle_dma() parameters from accepting
(struct page *page, size_t offset, size_t size) to (phys_addr_t phys,
size_t size). The existing semantics where callers are expected to
provide only kmap memory is continued here.

Make iommu_dma_map_phys() and iommu_dma_unmap_phys() respect
DMA_ATTR_MMIO.
DMA_ATTR_MMIO makes the functions behave the same as
iommu_dma_(un)map_resource():
- No swiotlb is possible
- No cache flushing is done (ATTR_MMIO should not be cached memory)
- prot for iommu_map() has IOMMU_MMIO not IOMMU_CACHE
This is preparation for replacing iommu_dma_map_resource() callers
with iommu_dma_map_phys(DMA_ATTR_MMIO) and removing
iommu_dma_(un)map_resource().

Rename the IOMMU DMA mapping functions to better reflect their actual
calling convention. The functions iommu_dma_map_page() and
iommu_dma_unmap_page() are renamed to iommu_dma_map_phys() and
iommu_dma_unmap_phys() respectively, as they already operate on physical
addresses rather than page structures.
The calling convention changes from accepting (struct page *page,
unsigned long offset) to (phys_addr_t phys), which eliminates the need
for page-to-physical address conversion within the functions. This
renaming prepares for the broader DMA API conversion from page-based
to physical address-based mapping throughout the kernel.
All callers are updated to pass physical addresses directly, including
dma_map_page_attrs(), scatterlist mapping functions, and DMA page
allocation helpers. The change simplifies the code by removing the
page_to_phys() + offset calculation that was previously done inside
the IOMMU functions.

This will replace the hacky use of DMA_ATTR_SKIP_CPU_SYNC to avoid
touching the possibly non-KVA MMIO memory.
Also correct the incorrect caching attribute for the IOMMU, MMIO
memory should not be cachable inside the IOMMU mapping or it can
possibly create system problems. Set IOMMU_MMIO for DMA_ATTR_MMIO.

All the other ref clocks provided by this driver have the bi_tcxo
as parent. The eDP refclk is the only one without a parent, leading
to reporting its rate as 0. So set its parent to bi_tcxo, just like
the rest of the refclks.
