When the binding for the Cadence spi controller was written, a dedicated
compatible was added for the zynq device. Later when zynqmp and
versal-net, which also use this spi controller IP, were added they did
not receive soc-specific compatibles. Add them now, with a fallback to
the existing compatible for the r1p6 version of the IP so that there
will be no functional change. Retain the r1p6 in the string, to match
what was done for zynq.
Disallow the cdns,spi-r1p6 compatible in isolation to "encourage" people
to actually add soc-specific compatible strings in the future.

Pull SoC driver updates from Arnd Bergmann:
"Lots of platform specific updates for Qualcomm SoCs, including a new
TEE subsystem driver for the Qualcomm QTEE firmware interface.
Added support for the Apple A11 SoC in drivers that are shared with
the M1/M2 series, among more updates for those.
Smaller platform specific driver updates for Renesas, ASpeed,
Broadcom, Nvidia, Mediatek, Amlogic, TI, Allwinner, and Freescale
SoCs.
Driver updates in the cache controller, memory controller and reset
controller subsystems.
SCMI firmware updates to add more features and improve robustness.
This includes support for having multiple SCMI providers in a single
system.
TEE subsystem support for protected DMA-bufs, allowing hardware to
access memory areas that managed by the kernel but remain inaccessible
from the CPU in EL1/EL0"

Apple SoC driver updates for 6.18
Krzysztof Kozlowski asked us to move away from generic compatibles:
- Adjust all dt-bindings to use apple,t8103-XXXX instead of apple,XXXX
as fallback and add a comment that the old generic list should no
longer be extended.
- Add new fallback compatibles to pinctrl, pmdomain, spi, and mca
drivers. These changes have been Acked by their subsystem maintainers
to be merged through our tree together with the dt-bindings.
Support for pre-M1 Apple Silicon:
- SART and mailbox gain support for Apple's A11, which are both
required for NVMe.
- NVMe also gains support for Apple's A11 and the nvme maintainers
prefer that we merge this through the soc tree together with
the mailbox and SART changes.
- SPMI compatibles for A11 and T2 have been added, also going through
the soc tree due to conflicts with the generic compatible removal and
because no driver change is required.

Merge series from Dharma Balasubiramani <dharma.b@microchip.com>:
This patch series adds support for SAM9X7 and sama7d65 QSPI controller
along with the SoC-specific capabilities.
After discussion with the devicetree maintainers we agreed to not extend
lists with the generic compatible "apple,spi" anymore [1]. Use
"apple,t8103-spi" as base compatible as it is the SoC the driver and
bindings were written for.
The SPI controller on Apple M2 Pro/Max/Ultra SoCs is compatible with
"apple,t8103-spi" so add its per-SoC compatible with the former as
fallback used by the existing driver.

Merge series from Xianwei Zhao <xianwei.zhao@amlogic.com>:
This Flash Controller is derived by adding an SPI path to the original
raw NAND controller. This controller supports two modes: raw mode and
SPI mode. The raw mode has already been implemented in the community
(drivers/mtd/nand/raw/meson_nand.c).
This submission supports the SPI mode.
Add the drivers and bindings corresponding to the SPI Flash Controller.
Merge series from James Clark <james.clark@linaro.org>:
Improve usability of target mode by reporting FIFO errors and increasing
the buffer size when DMA is used. While we're touching DMA stuff also
switch to non-coherent memory, although this is unrelated to target
mode.
With the combination of the commit to increase the DMA buffer size and
the commit to use non-coherent memory, the host mode performance figures
are as follows on S32G3:
# spidev_test --device /dev/spidev1.0 --bpw 8 --size <test_size> --cpha --iter 10000000 --speed 10000000
Coherent (4096 byte transfers): 6534 kbps
Non-coherent: 7347 kbps
Coherent (16 byte transfers): 447 kbps
Non-coherent: 448 kbps
Just for comparison running the same test in XSPI mode:
4096 byte transfers: 2143 kbps
16 byte transfers: 637 kbps
These tests required hacking S32G3 to use DMA in host mode, although
the figures should be representative of target mode too where DMA is
used. And the other devices that use DMA in host mode should see similar
improvements.

Add support SPI NOR flash memory controller for SG2042, using upstreamed
SG2044 SPI NOR driver.
Tested on SG2042 Pioneer Box, read, write operations.
Thanks Chen Wang who provided machine and guidance.
Merge series from Xianwei Zhao <xianwei.zhao@amlogic.com>:
Introduced support for the new SPI IP (SPISG). The SPISG is
a communication-oriented SPI controller from Amlogic,supporting
three operation modes: PIO, block DMA, and scatter-gather DMA.
Add the drivers and device tree bindings corresponding to the SPISG.
With further testing, directly using the spi-sg2044-nor driver on SG2042
does not work. SG2042 is found to lack full compatibility with SG2044.
SG2044 has OPT register and it's necessary to write but SG2042 does not.
Due to other possible hardware detail differences, it is better
to bind SG2042 independently.

A year ago we spent quite some work trying to get PCI into better shape.
Some pci_ functions can be sometimes managed with devres, which is
obviously bad. We want to provide an obvious API, where pci_ functions
are never, and pcim_ functions are always managed.
Thus, everyone enabling his device with pcim_enable_device() must be
ported to pcim_ functions. Porting all users will later enable us to
significantly simplify parts of the PCI subsystem. See here [1] for
details.
This patch series does that for sound.
Feel free to squash the commits as you see fit.
