Pull non-MM updates from Andrew Morton:

 - Kuan-Wei Chiu has developed the well-named series "lib min_heap: Min
   heap optimizations".

 - Kuan-Wei Chiu has also sped up the library sorting code in the series
   "lib/sort: Optimize the number of swaps and comparisons".

   namespace to alter its IPC and MQ limits. The series is "Allow to
   change ipc/mq sysctls inside ipc namespace".

 - Geert Uytterhoeven has contributed some dhrystone maintenance work in
   the series "lib: dhry: miscellaneous cleanups".

 - Nathan Chancellor has updated our build tools requirements in the
   series "Bump the minimum supported version of LLVM to 13.0.1".

 - Muhammad Usama Anjum continues with the selftests maintenance work in
   the series "selftests/mm: Improve run_vmtests.sh".

 - Oleg Nesterov has done some maintenance work against the signal code
   in the series "get_signal: minor cleanups and fix".

Plus the usual shower of singleton patches in various parts of the tree.
Please see the individual changelogs for details.

tpm: tis_i2c: Add compatible string nuvoton,npct75x

2024-03-11T22:26:06+00:00

Add "nuvoton,npct75x" as well as the fallback compatible string
"tcg,tpm-tis-i2c" to the TPM TIS I²C driver.  They're used by:

  arch/arm/boot/dts/aspeed/aspeed-bmc-ibm-bonnell.dts
  arch/arm/boot/dts/aspeed/aspeed-bmc-ibm-everest.dts

And by all accounts, NPCT75x is supported by the driver:

tpm_tis: Add compatible string atmel,at97sc3204

2024-03-11T22:26:06+00:00

Commit 420d439849ca ("tpm_tis: Allow tpm_tis to be bound using DT")
added the fallback compatible "tcg,tpm-tis-mmio" to the TPM TIS driver,
but not the chip-specific "atmel,at97sc3204".  However it did document
it as a valid compatible string.

Add it to tis_of_platform_match[] for consistency.

tpm_tis_spi: Add compatible string atmel,attpm20p

2024-03-11T22:26:06+00:00

Commit 4f2a348aa365 ("arm64: dts: imx8mm-venice-gw73xx: add TPM device")
added a devicetree node for the Trusted Platform Module on certain
Gateworks boards.

The commit only used the generic "tcg,tpm_tis-spi" compatible string,
but public documentation shows that the chip is an ATTPM20P from Atmel
(nowadays Microchip):
https://trac.gateworks.com/wiki/tpm

Add the chip to the supported compatible strings of the TPM TIS SPI
driver.

For reference, a datasheet is available at:

tpm,tpm_tis: Avoid warning splat at shutdown

2024-03-11T22:26:05+00:00

If interrupts are not activated the work struct 'free_irq_work' is not
initialized. This results in a warning splat at module shutdown.

Fix this by always initializing the work regardless of whether interrupts
are activated or not.

tpm/tpm_ftpm_tee: fix all kernel-doc warnings

2024-03-11T22:26:05+00:00

Change @pdev to @dev in 2 places to match the function parameters.
Correct one function name in kernel-doc comment to match the function
implementation.

This prevents these warnings:

tpm_ftpm_tee.c:217: warning: Function parameter or struct member 'dev' not described in 'ftpm_tee_probe'
tpm_ftpm_tee.c:217: warning: Excess function parameter 'pdev' description in 'ftpm_tee_probe'

Normalise "name (ad@dr)" MODULE_AUTHORs to "name "

2024-03-06T21:07:39+00:00

Found with git grep 'MODULE_AUTHOR(".*([^)]*@'
Fixed with
  sed -i '/MODULE_AUTHOR(".*([^)]*@/{s/ (/ "/;s/)and/> and/}' \
    $(git grep -l 'MODULE_AUTHOR(".*([^)]*@')

Also:
  in drivers/media/usb/siano/smsusb.c normalise ", INC" to ", Inc";
     this is what every other MODULE_AUTHOR for this company says,
     and it's what the header says
  in drivers/sbus/char/openprom.c normalise a double-spaced separator;
     this is clearly copied from the copyright header,
     where the names are aligned on consecutive lines thusly:

      * Copyright (C) 1996 Eddie C. Dost  (ecd@skynet.be)
     but the authorship branding is single-line

tpm_tis_spi: Follow renaming of SPI "master" to "controller"

2024-02-08T11:54:56+00:00

In commit 8caab75fd2c2 ("spi: Generalize SPI "master" to "controller"")
some functions and struct members were renamed. To not break all drivers
compatibility macros were provided.

To be able to remove these compatibility macros push the renaming into
this driver.
