15513eefac MIPS/mtd: Handle READY GPIO in generic NAND platform data
The callbacks into the MIPS RB532 platform to read the GPIO pin
indicating that the NAND chip is ready are oldschool and does
not assign GPIOs as properties to the NAND device.

Add a capability to the generic platform NAND chip driver to use
a GPIO line to detect if a NAND chip is ready and override the
platform-local drv_ready() callback with this check if the GPIO
is present.

This makes it possible to drop the legacy include header
<linux/gpio.h> from the RB532 devices.

42671e9c1e MIPS/input: Move RB532 button to GPIO descriptors
Convert the Mikrotik RouterBoard RB532 to use GPIO descriptors
by defining a software node for the GPIO chip, then register
the button platform device with full info passing the GPIO
as a device property.

This can be used as a base to move more of the RB532 devices
over to passing GPIOs using device properties.

Use the GPIO_ACTIVE_LOW flag and drop the inversion in the
rb532_button_pressed() function.

f992846d0b MIPS: validate DT bootargs before appending them
bootcmdline_scan_chosen() fetches the raw flat-DT bootargs property and
passes it straight to bootcmdline_append(). That helper later feeds the
same pointer into strlcat(), which computes strlen(src) before copying.
Flat DT properties are external boot input, and this path does not
prove that bootargs is NUL-terminated within its declared bounds.

Reject unterminated bootargs properties before appending them to the
kernel command line.

8ab1e58ca9 clk: eyeq: Skip post-divisor when computing PLL frequency
The output of the PLL is routed before the post-divisor so it should be
ignored when computing the frequency of the PLL, functional change is
implemented to reflect how the clock signal is wired internally.

For the PLL of the EyeQ5, EyeQ6L, and EyeQ6H, this change has no impact
as the post-divisor is either reported as disabled or set to 1. The PLL
frequency is the same before and after the post-divisor.

For the PLL in EyeQ6Lplus, however, the post-divisor is not 1, so it must
be ignored to compute the correct frequency.

7cfa9474b9 pinctrl: eyeq5: Use match data
Instead of using the pin descriptions, pin functions and register offsets
of the EyeQ5 directly, access those via a pointer to a newly introduced
struct eq5p_match_data.

This structure contains, in addition to the pin descriptions and pin
functions, an array of pin banks. Each bank holds the number of pins
and the register offsets.

All functions accessing a pin now use a pointer to a bank structure and
an offset inside that bank. The conversion from a pin number to a bank
and an offset is done in the new function eq5p_pin_to_bank_offset(),
which replace eq5p_pin_to_bank() and eq5p_pin_to_offset().

All the data related to the EyeQ5 is declared with the eq5p_eyeq5_
prefix to distinguish it from the common code.

During the probe, we use the parent OF node to get the match data.
We cannot directly use an OF node since pinctrl-eyeq5 is an auxiliary
device of clk-eyeq.

79b888ee4c MIPS: dts: loongson64g-package: Switch to Loongson UART driver
Loongson64g is Loongson 3A4000, whose UART controller is compatible with
Loongson 2K1500, which is NS16550A-compatible with an additional
fractional frequency divisor register.

Update the compatible strings to reflect this, so that 3A4000 can
benefit from the fractional frequency divisor provided by loongson-uart.
This is required on some devices, otherwise their UART can't work at
some high baud rates, e.g., 115200.

Tested on Loongson-LS3A4000-7A1000-NUC-SE with a 25MHz UART clock.
Without fractional frequency divisor, the actual baud rate was 111607
(25MHz / 16 / 14, measured value: 111545) and some USB-to-UART
converters couldn't work with it at all. With fractional frequency
divisor, the measured baud rate becomes 115207, which is quite accurate.

Disabling power and clock are unnecessary for MT7620 and will be

driver is not selected. The MT7628 GPIO pinctrl has been removed
because this should be done in device-tree. Some delay intervals
have also been increased to follow the recommendations of the SoC
SDK and datasheet. Tested on both MT7620 and MT7628.

56236b7f6f MIPS: DEC: Rate-limit memory errors for ECC systems
Prevent the system from becoming unusable due to a flood of memory error
messages with DECstation and DECsystem models using ECC, that is KN02,
KN03 and KN05 systems.  It seems common for gradual oxidation of memory
module contacts to cause memory errors to eventually develop and while
ECC takes care of correcting them and the system affected can continue
operating normally until the contacts have been cleaned, the unlimited
messages make the system spend all its time on producing them, therefore
preventing it from being used.

Rate-limiting removes the load from the system and enables its normal
operation, e.g.:

Bus error interrupt: CPU memory read ECC error at 0x139cfb04
  ECC syndrome 0x54 -- corrected single bit error at data bit D3

keep the syntax consistent and the register referred is hardwired, there
is no point in having it here as it has no effect on code generation.

Pull char/misc/iio driver fixes from Greg KH:
 "Here are a relativly large number of small char/misc/iio and other
  driver fixes for 7.0-rc7. There's a bunch, but overall they are all
  small fixes for issues that people have been having that I finally
  caught up with getting merged due to delays on my end.

  The "largest" change overall is just some documentation updates to the
  security-bugs.rst file to hopefully tell the AI tools (and any users
  that actually read the documentation), how to send us better security
  bug reports as the quantity of reports these past few weeks has
  increased dramatically due to tools getting better at "finding"
  things.

  Included in here are:
   - lots of small IIO driver fixes for issues reported in 7.0-rc
   - gpib driver fixes
   - comedi driver fixes
   - interconnect driver fix
   - nvmem driver fixes
   - mei driver fix
   - counter driver fix
   - binder rust driver fixes
   - some other small misc driver fixes

  All of these have been in linux-next this week with no reported issues"

Pull USB/Thunderbolt fixes from Greg KH:
 "Here are a bunch of USB and Thunderbolt fixes (most all are USB) for
  7.0-rc7. More than I normally like this late in the release cycle,
  partly due to my recent travels, and partly due to people banging away
  on the USB gadget interfaces and apis more than normal (big shoutout
  to Android for getting the vendors to actually work upstream on this,
  that's a huge win overall for everyone here)

  Included in here are:
   - Small thunderbolt fix
   - new USB serial driver ids added
   - typec driver fixes
   - gadget driver fixes for some disconnect issues
   - other usb gadget driver fixes for reported problems with binding
     and unbinding devices as happens when a gadget device connects /
     disconnects from a system it is plugged into (or it switches device
     mode at a user's request, these things are complex little
     beasts...)
   - usb offload fixes (where USB audio tunnels through the controller
     while the main CPU is asleep) for when EMP spikes hit the system
     causing disconnects to happen (as often happens with static
     electricity in the winter months). This has been much reported by
     at least one vendor, and resolves the issues they have been seeing
     with this codepath. Can't wait for the "formal methods are the
     answer!" people to try to model that one properly...
   - Other small usb driver fixes for issues reported.

  All of these have been in linux-next this week, and before, with no
  reported issues, and I've personally been stressing these harder than
  normal on my systems here with no problems"

9156585280 ACPI: RIMT: Add dependency between iommu and devices
EPROBE_DEFER ensures IOMMU devices are probed before the devices that
depend on them. During shutdown, however, the IOMMU may be removed
first, leading to issues. To avoid this, a device link is added
which enforces the correct removal order.

Fix the build of non-kernel code that includes the RISC-V ptrace uapi
header, and the RISC-V validate_v_ptrace.c kselftest, by using the

3033b2b1e3 riscv: Reset pmm when PR_TAGGED_ADDR_ENABLE is not set
In set_tagged_addr_ctrl(), when PR_TAGGED_ADDR_ENABLE is not set, pmlen
is correctly set to 0, but it forgets to reset pmm. This results in the
CPU pmm state not corresponding to the software pmlen state.

Fix this by resetting pmm along with pmlen.

57f0253bc1 riscv: make runtime const not usable by modules
Similar as commit 284922f4c5 ("x86: uaccess: don't use runtime-const
rewriting in modules") does, make riscv's runtime const not usable by
modules too, to "make sure this doesn't get forgotten the next time
somebody wants to do runtime constant optimizations". The reason is
well explained in the above commit: "The runtime-const infrastructure
was never designed to handle the modular case, because the constant
fixup is only done at boot time for core kernel code."

6b60a128c2 riscv: patch: Avoid early phys_to_page()
Similarly to commit 8d09e2d569 ("arm64: patching: avoid early
page_to_phys()"), avoid using phys_to_page() for the kernel address case
in patch_map().

Since this is called from apply_boot_alternatives() in setup_arch(), and
commit 4267739cab ("arch, mm: consolidate initialization of SPARSE
memory model") has moved sparse_init() to after setup_arch(),
phys_to_page() is not available there yet, and it panics on boot with
SPARSEMEM on RV32, which does not use SPARSEMEM_VMEMMAP.

834911eb8e riscv: kgdb: fix several debug register assignment bugs
Fix several bugs in the RISC-V kgdb implementation:

- The element of dbg_reg_def[] that is supposed to pertain to the S1
  register embeds instead the struct pt_regs offset of the A1
  register.  Fix this to use the S1 register offset in struct pt_regs.

- The sleeping_thread_to_gdb_regs() function copies the value of the
  S10 register into the gdb_regs[] array element meant for the S9
  register, and copies the value of the S11 register into the array
  element meant for the S10 register.  It also neglects to copy the
  value of the S11 register.  Fix all of these issues.

f387e2e2b9 Documentation: fix two typos in latest update to the security report howto
In previous patch "Documentation: clarify the mandatory and desirable
info for security reports" I left two typos that I didn't detect in local
checks. One is "get_maintainers.pl" (no 's' in the script name), and the
other one is a missing closing quote after "Reported-by", which didn't
have effect here but I don't know if it can break rendering elsewhere
(e.g. on the public HTML page). Better fix it before it gets merged.
