f54b69a57a spi: sophgo: Add SPI NOR controller for SG2042
Merge series from Zixian Zeng <sycamoremoon376@gmail.com>:

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.

317fb4c387 support for amlogic the new SPI IP
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.

7438379cfc spi: dt-bindings: spi-sg2044-nor: Change SOPHGO SG2042
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.

d5255ae7ec spi: dt-bindings: spi-mux: Drop "spi-max-frequency" as required
There's little reason to require the SPI mux to define a maximum bus
frequency as the muxing is just the chip select and devices still define
their maximum freq. In fact, several users don't set "spi-max-frequency"
which caused warnings.

02ca789818 AsoC: Phase out hybrid PCI devres
Merge series from Philipp Stanner <phasta@kernel.org>:

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.

2f24482304 Merge tag 'soc-dt-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC devicetree updates from Arnd Bergmann:
 "There is new support for additional on-chip devices on Apple,
  Mediatek, Renesas, Rockchip, Samsung, Google, TI, ST, Nvidia and
  Amlogic devices.

  The Arm Morello reference platform gets a devicetree for booting in
  normal aarch64 mode. The hardware supports experimental CHERI support,
  which requires a modified kernel.

  The AMD (formerly Xilinx) Versal NET SoC gets added, this is a
  combined FPGA with Cortex-A78 CPUs in a SoC.

  Six new ST STM32MP2 SoC variants are added. Like the earlier
  STM32MP25, the MP211, MP213, MP215, MP231, MP233 and MP235 models are
  based on one or two Cortex-A35 cores but each feature a different set
  of I/O devices.

  Mediatek MT8370 is a minor variation of MT8390 with fewer CPU and GPU
  cores

  Apple T2 is the baseboard management controller on earlier Intel CPU
  based Macs, with 16 models now gaining initial support.

  All the above come with dts files for the reference boards. In
  addition, these boards are added for the SoCs that are already
  supported:

   - The Milk-V Jupiter board based on SpacemiT K1/M1

   - NetCube Systems Kumquat board based on the 32-bit Allwinner V3s SoC

   - Three boards based on 32-bit stm32mp1

   - 11 distinct board variants from Toradex and one from Variscite, all
     based on i.MX6

   - Google Pixel Pro 6 phone based on gs101 (Tensor)

   - Three additional variants of the i.MX8MP based "Skov" board

   - A second variant of the i.MX95 EVK board

   - Two boards based on Renesas SoCs

   - Four boards based the Rockchip RK35xx series, plus the RK3588 'MNT
     Reform 2' laptop"

8b35d65387 spi: dt-bindings: cdns,qspi-nor: Deprecate the Cadence compatible alone
The initial SPI controller IP from Cadence has always been implemented
into controllers from various hardware manufacturers and because of
that, it has always been (rightfully) doubled with a more specific
compatible. There are likely no reasons to keep this compatible
legitimate, alone. Make sure people do not get mislead by officially
deprecating this compatible.

While at deprecating, let's update the examples to avoid documenting
deprecated properties.

77289a8a8b spi: dt-bindings: cdns,qspi-nor: Be more descriptive regarding what this controller is
Despite being very common in commit logs, SPI NOR controllers simply do
not exist. At least, they are not as specific as the name implies. There
are SPI memory controllers which are indeed "specialized" and optimized
for handling "memories", but most of them are just generic and accept
almost any kind of opcode, address, dummy and data cycles, making them
as suitable for NANDs than NORs.

Furthermore, this controller supports any kind of bus, from single to
octal NAND, so make it clear.

Also add a comment to mention that the initial compatible naming is too
specific (but obviously kept for backward compatibility reasons).

Merge series from patrice.chotard@foss.st.com:

This series adds SPI NOR support for STM32MP25 SoCs from STMicroelectronics.

On STM32MP25 SoCs family, an Octo Memory Manager block manages the muxing,
the memory area split, the chip select override and the time constraint
between its 2 Octo SPI children.

Due to these depedencies, this series adds support for:
  - Octo Memory Manager driver (not applied for SPI).
  - Octo SPI driver.
  - yaml schema for Octo Memory Manager and Octo SPI drivers.

The device tree files adds Octo Memory Manager and its 2 associated Octo
SPI chidren in stm32mp251.dtsi and adds SPI NOR support in stm32mp257f-ev1
board.

Main features of the Octo-SPI controller :
  - support sNOR / sNAND / HyperRAM™ and HyperFlash™ devices.
  - Three functional modes: indirect, automatic-status polling,
    memory-mapped.
  - Up to 4 Gbytes of external memory can be addressed in indirect
    mode (per physical port and per CS), and up to 256 Mbytes in
    memory-mapped mode (combined for both physical ports and per CS).
  - Single-, dual-, quad-, and octal-SPI communication.
  - Dual-quad communication.
  - Single data rate (SDR) and double transfer rate (DTR).
  - Maximum target frequency is 133 MHz for SDR and 133 MHz for DTR.
  - Data strobe support.
  - DMA channel for indirect mode.
  - Double CS mapping that allows two external flash devices to be
    addressed with a single OCTOSPI controller mapped on a single
    OCTOSPI port.

f0ceedd52a dt-bindings: xilinx: Deprecate header with firmware constants
Firmware contants do not fit the purpose of bindings because they are not
independent IDs for abstractions. They are more or less just contants which
better to wire via header with DT which is using it.
That's why add deprecated message to dt binding header and also update
existing dt bindings not to use macros from the header  and replace them by
it's value. Actually value is not relevant because it is only example.

The similar changes have been done by commit 9d92925768 ("dt-bindings:
