gpio: mt7621: fix interrupt banks mapping on gpio chips
The GPIO controller's registers are organized as sets of eight 32-bit
registers with each set controlling a bank of up to 32 pins. A single
interrupt is shared for all of the banks handled by the controller.
The driver implements this using three gpio chip instances every one
with its own irq chip. Every single pin can generate interrupts having
a total of 96 possible interrupts here. It looks like there is a problem
with interrupts being properly mapped to the gpio bank using this solution.
This problem report is in the following lore's link [0].
Device tree is using two cells for this, so only the interrupt pin and the
interrupt type are described there. Changing to have three cells to setup
also the bank and implement 'of_node_instance_match()' would also work but
this would be an ABI breakage and also a bit incoherent since gpios itself
are also using two cells and properly mapped in desired bank using through
its pin number on 'of_xlate()'.
That said, register a linear IRQ domain of the total of 96 interrupts shared
with the three gpio chip instances so the bank and the interrupt is properly
decoded and devices using gpio IRQs properly work.

gpio: remove obsolete UAF FIXMEs from lookup paths
The ACPI and swnode GPIO lookup backends both temporarily grab a reference
to the gpio_device, resolve the descriptor, and then drop the reference
before returning the descriptor to the caller. They carry FIXME comments
warning that the descriptor is being returned without its backing device
reference.
However, the gpiod_find_and_request() core functionally prevents any
use-after-free window by wrapping the entire lookup operation inside the
gpio_devices_srcu read lock. The lookup functions are correct to drop
their references since the caller (gpiod_request) will subsequently take
its own permanent module and device references safely.
Remove these obsolete FIXMEs to prevent misleading future subsystem
developers.

The EIO GPIO block has 2 banks with 26 GPIOs each (52 total).
The GPIO width cannot be determined from the hardware registers,
the driver relies on the compatible string to select the correct
bank/pin configuration. A new compatible is therefore required.
The block is currently present on xa2ve3288 silicon.
The compatible string uses version 1.0 matching the IP core version.

gpio: regmap: Don't set a fixed direction line
If a GPIO line has a fixed direction, report an error if a consumer
anyway tries to set the direction to something other than what it is
hardcoded to.
This didn't happen much before because what we supported was all lines
input or output and then the implementer would probably not specify the
direction registers, but with sparse fixed direction we can have
a mixture so let's take this into account.
As a consequence, since gpio_regmap_set_direction() can now fail, alter
the semantics in gpio_regmap_direction_output() such that we first check
if we can set the direction to output before we set the value and the
direction.

gpiolib: add gpiod_is_single_ended() helper
The direction of a single-ended (open-drain or open-source) GPIO line
cannot always be reliably determined by reading hardware registers.
In true open-drain implementations, the "high" state is achieved by
entering a high-impedance mode, which many hardware controllers report
as "input" even if the software intends to use it as an output.
This creates issues for consumer drivers (like I2C) that rely on
gpiod_get_direction() to decide if a line can be driven.
Introduce gpiod_is_single_ended() to allow consumers to check the
software configuration (GPIO_FLAG_OPEN_DRAIN/GPIO_FLAG_OPEN_SOURCE) of
a descriptor. This provides a robust way to identify lines that are
capable of being driven, regardless of their instantaneous hardware state.

gpio: 74x164: support lines-initial-states for boot-time output state
74HC595 and 74LVC594 chains retain their output state from the first

from a zero-initialised buffer, so every output comes up low until user
space issues a write. Boards that rely on the chain to drive signals
whose power-on state matters (active-low indicators, reset lines, etc.)
have no way to express the desired initial pattern via DT.
Read the optional lines-initial-states bitmask, recently documented for
this binding, into chip->buffer before the first
__gen_74x164_write_config() so the chain comes up in a known state on
the very first SPI transaction. Bit N maps to GPIO line N (matching the
nxp,pcf8575 convention); on this output-only device, bit=0 drives the
line low and bit=1 drives it high. Property absence keeps the existing

dt-bindings: gpio: fairchild,74hc595: add lines-initial-states property
The 74HC595 and 74LVC594 shift registers latch their outputs until the
first serial write, so boards that depend on a specific power-on pattern
(for example active-low indicators, reset lines, or other signals that
must come up non-zero) have no way to express that today: the Linux
driver always writes zeros from its zero-initialised buffer during
probe.
Document support for the existing lines-initial-states bitmask, already
defined for nxp,pcf8575, so the same convention covers this output-only
device. Bit N corresponds to GPIO line N. Because the 74HC595/74LVC594
family is push-pull output only (no input mode, no high-impedance state
under software control), bit=0 drives the line low and bit=1 drives it
high; this differs from nxp,pcf8575, where the 0/1 polarity reflects the
quasi-bidirectional nature of that part.
The bitmask covers up to 32 lines, which fits the typical 1-4 chip
cascades that appear in tree. Should longer chains require seeding in
the future, the property can be extended to a uint32-array without
breaking the bit-N-equals-line-N convention.

clk: bcm: rpi: Mark VEC clock as CLK_IGNORE_UNUSED
On Raspberry Pi 3B, the VEC clock is used by the VideoCore firmware
display driver, which remains active until the vc4 driver loads and
sends NOTIFY_DISPLAY_DONE. If this clock is disabled during boot, a bus
lockup happens and the firmware becomes unresponsive, causing a complete
system lockup.
Mark the VEC clock with CLK_IGNORE_UNUSED so it survives the unused
clock disablement and remains available until the vc4 driver takes over
display management.

- Fix accounting of persistent ring buffer rewind
On boot up, the head page is moved back to the earliest point of the
saved ring buffer. This is because the ring buffer being read by user
space on a crash may not save the part it read. Rewinding the head
page back to the earliest saved position helps keep those events from
being lost.
The number of events is also read during boot up and displayed in the
stats file in the tracefs directory. It's also used for other
accounting as well. On boot up, the "reader page" is accounted for
but a rewind may put it back into the buffer and then the reader page
may be accounted for again.
Save off the original reader page and skip accounting it when
scanning the pages in the ring buffer.

- A nospec addition for direct descriptor file updating. Rest of the

- Various minor defensive changes that claude identified and suggested
terrible fixes for, turned into actually useful cleanups:
- Use kvfree() for the imu cache. These can come from kmalloc or
vmalloc depending on size, but the in-cache ones are capped
where it's always kmalloc based. Change to kvfree() in the
cleanup path, making future changes unlikely to mess that up
- Negative kbuf consumption lengths. Can't happen right now, but
cqe->res is used directly, which if other codes changes could
then be an error value
- Fix for an issue with the futex code, where partial wakes on a
vectored fuxes would potentially wake the same futex twice, rather
than move on to the next one. This could confuse an application as it
would've expected the next futex to have been woken

Merge tag 'riscv-for-linus-7.1-mw1' of git://git./linux/kernel/git/riscv/linux
Pull RISC-V updates from Paul Walmsley:
"There is one significant change outside arch/riscv in this pull
request: the addition of a set of KUnit tests for strlen(), strnlen(),
and strrchr().
Otherwise, the most notable changes are to add some RISC-V-specific
string function implementations, to remove XIP kernel support, to add
hardware error exception handling, and to optimize our runtime
unaligned access speed testing.
A few comments on the motivation for removing XIP support. It's been
broken in the RISC-V kernel for months. The code is not easy to
maintain. Furthermore, for XIP support to truly be useful for RISC-V,
we think that compile-time feature switches would need to be added for
many of the RISC-V ISA features and microarchitectural properties that
are currently implemented with runtime patching. No one has stepped
forward to take responsibility for that work, so many of us think it's
best to remove it until clear use cases and champions emerge.
Summary:
- Add Kunit correctness testing and microbenchmarks for strlen(),
strnlen(), and strrchr()
- Add RISC-V-specific strnlen(), strchr(), strrchr() implementations
- Add hardware error exception handling
- Clean up and optimize our unaligned access probe code
- Enable HAVE_IOREMAP_PROT to be able to use generic_access_phys()
- Remove XIP kernel support
- Warn when addresses outside the vmemmap range are passed to
vmemmap_populate()
- Update the ACPI FADT revision check to warn if it's not at least
ACPI v6.6, which is when key RISC-V-specific tables were added to
the specification
- Increase COMMAND_LINE_SIZE to 2048 to match ARM64, x86, PowerPC,
etc.
- Make kaslr_offset() a static inline function, since there's no need
for it to show up in the symbol table
- Add KASLR offset and SATP to the VMCOREINFO ELF notes to improve
kdump support
- Add Makefile cleanup rule for vdso_cfi copied source files, and add
a .gitignore for the build artifacts in that directory
- Remove some redundant ifdefs that check Kconfig macros
- Add missing SPDX license tag to the CFI selftest
- Simplify UTS_MACHINE assignment in the RISC-V Makefile
- Clarify some unclear comments and remove some superfluous comments
- Fix various English typos across the RISC-V codebase"

"Delete some obsolete networking code
Old code like amateur radio and NFC have long been a burden to core
networking developers. syzbot loves to find bugs in BKL-era code, and
noobs try to fix them.
If we want to have a fighting chance of surviving the LLM-pocalypse
this code needs to find a dedicated owner or get deleted. We've talked
about these deletions multiple times in the past and every time
someone wanted the code to stay. It is never very clear to me how many
of those people actually use the code vs are just nostalgic to see it
go. Amateur radio did have occasional users (or so I think) but most
users switched to user space implementations since its all super slow
stuff. Nobody stepped up to maintain the kernel code.
We were lucky enough to find someone who wants to help with NFC so
we're giving that a chance. Let's try to put the rest of this code
behind us"
