spi: pxa2xx: Remove the unneeded result variable
Return the value clk_prepare_enable() directly instead of storing it in
another redundant variable.

spi: stm32_qspi: use QSPI bus as 8 lines communication channel
Merge series from patrice.chotard@foss.st.com <patrice.chotard@foss.st.com>:

The goal of this series is to allow to use QSPI bus as a 8 lines communication
channel for specific purpose.

The QSPI block offers the possibility to communicate with 2 flashes in
parrallel using the dual flash mode, 8 data lines are then used.
Usage of cs-gpios populated and spi-tx-bus-width / spi-rx-bus-width both set to 8,
is needed to enable dual flash mode.

The addition of the legacy transfer_one_message() spi callback is also needed
as currently the stm32-qspi driver only supports spi_controller_mem_ops API.

spi: dw: Quite logging on deferred controller registration
It's pretty possible to have the spi_register_controller() method
returning -EPROBE_DEFER status in case, for instance, if the GPIOs used
for the CS implementation aren't ready to be requested due to the
corresponding platform devices still pending to be probed. Let's make sure
the DW SSI driver won't print error message in that case by calling the
dev_err_probe() function if the SPI-registration procedure exited with
a non-zero status.

spi: stm32_qspi: Add transfer_one_message() spi callback
Add transfer_one_message() spi callback in order to use the QSPI interface
as a communication channel using up to 8 qspi lines (QSPI configured
in dual flash mode).
To enable this mode, both spi-rx-bus-width and spi-tx-bus-width must be

spi: intel: Add support for second flash chip
Intel SPI flash controller has been supporting two chip selects long
time already even if the most common configuration is to have a single
flash chip for the BIOS and related data. This adds support for the
second chip select if we find out that there are two flash components
(this information is available in the mandatory flash descriptor on the
first chip). The second chip is exposed as is without any partition
information.

spi: amd: Setup all xfers before opcode execution
The AMD SPI controller hardware seems to expect the FIFO buffer to be
fully setup with the details of all transfers in the SPI message before
it is able to start processing the data in a reliable way.

Furthermore, it imposes a strict ordering restriction, in the sense that
all TX transfers must be handled prior any RX transfer.

Hence, let's ensure amd_spi_execute_opcode() is called only once, after
all TX transfers have been setup, and process any remaining RX transfers
afterwards, in a second iteration.

Additionally, get rid of the unnecessary AMD_SPI_XFER_TX/RX defines and
improve error handling.

spi/panel: dt-bindings: drop 3-wire from common properties
The spi-3wire property is device specific and should be accepted only if
device really needs them.  Drop it from common spi-peripheral-props.yaml
schema, mention in few panel drivers which use it and include instead in
the SPI controller bindings.  The controller bindings will provide
spi-3wire type validation and one place for description.  Each device
schema must list the property if it is applicable.

The Samsung S6E63M0 panel uses also spi-cpha/cpol properties on at least
one board (ste-ux500-samsung-janice/dts), so add also these to the
panel's bindings.

Linus Torvalds d785610f05 powerpc fixes for 6.0 #2
- Ensure we never emit lwarx with EH=1 on 32-bit, because some 32-bit CPUs trap on it
    rather than ignoring it as they should.
 
  - Fix ftrace when building with clang, which was broken by some refactoring.
 
  - A couple of other minor fixes.

David Howells 8549a26308 afs: Enable multipage folio support
Enable multipage folio support for the afs filesystem.

Support has already been implemented in netfslib, fscache and cachefiles
and in most of afs, but I've waited for Matthew Wilcox's latest folio
changes.

Note that it does require a change to afs_write_begin() to return the
correct subpage.  This is a "temporary" change as we're working on
getting rid of the need for ->write_begin() and ->write_end()
completely, at least as far as network filesystems are concerned - but
it doesn't prevent afs from making use of the capability.

Carsten Haitzler 7391db6459 perf test: Refactor shell tests allowing subdirs
This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.

To support subdirs I have to recurse so it's time to refactor the code
to allow this and centralize the shell script finding into one location
and only one single scan that builds a list of all the found tests in
memory instead of it being duplicated in 3 places.

This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass of
opening files).

It also more cleanly filters scripts to see only *.sh files thus
skipping random other files in directories like *~ backup files, other
random junk/data files that may appear and the scripts must be
executable to make the cut (this ensures the script lib dir is not seen
as scripts to run).

This avoids perf test running previous older versions of test scripts
that are editor backup files as well as skipping perf.data files that
may appear and so on.
