f102039270 Merge tag 'soc-dt-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC devicetree updates from Arnd Bergmann:
 "We see the addition of eleven new SoCs, including a total of sixx
  arm64 chips from Qualcomm alone. Overall, the Qualcomm platforms once
  again make up the majority of all changes, after a couple of quieter
  releases.

  The new SoCs in this branch are:

   - Microchip sama7d65 is a new 32-bit embedded chip with a single
     Cortex-A7 and the current high end of the old Atmel SoC line.

   - Samsung Exynos 9810 is a mobile phone chip used in some older
     phones like the Samsung Galaxy S9

   - Renesas R-Car V4H ES3.0 (R8A779G3) is an updated version of the V4H
     (R8A779G0) low-power automotive SoC

   - Renesas RZ/G3E (R0A09G047) is a family of embedded chips using
     Cortex-A55 cores

   - Qualcomm Snapdragon 8 Elite (SM8750) is a new phone chip based on
     Qualcomm's Oryon CPU cores.

   - Qualcomm Snapdragon AR2 (SAR2130P) is a SoC for augmented reality
     glasses.

   - Qualcomm IQ6 (QCS610) and IQ8 (QCS8300) are two industrial IOT
     platforms.

   - Snapdragon 425 (MSM8917) is a mobile phone SoC from 2016

   - Qualcomm IPQ5424 is a Wi-Fi 7 networking chip

  All of the above are part of already supported SoC families that only
  need new devicetree files. Two additional SoCs in new families are
  part of a separate branch.

  There are 48 new machines in total, including six arm32 ones based on
  aspeed. broadcom, microchip and st SoCs all using Cortex-A7 cores, and
  a single risc-v board, the Banana Pi R3.

  The remaining ones use arm64 chips from Broadcom, Samsung, NXP,
  Mediatek, Qualcomm, Renesas and Rockchips and cover development
  boards, phones, laptops, industrial machines routers.

 A lot of ongoing work is for cleaning up build time warnings and other
 issues, in addition to the new machines and added features"

5c1ae7729e arm64: dts: broadcom: bcmbca: bcm4908: Add DT for Zyxel EX3510-B
Zyxel EX3510-B is a WiFi 6 capable home gateway (family) based on the
BCM4906 SoC, with 512MiB of RAM and 512MiB of NAND flash. WiFi support
consists of a BCM6710 and a BCM6715 attached to separate PCIe buses.

Add an initial devicetree for this system, with support for:
- Onboard UART (per base dtsi)
- USB (2.0 only; superspeed devices are treated as high-speed due to an
    unknown cause)
- Both buttons (rear reset, front WPS)
- Almost all LEDs:
  - Power (red/green)
  - Internet (red/green)
  - WAN (green)
  - LAN (green; anode is connected to GPIO 13 so currently
      nonfunctioning)
  - USB (green)
  - WPS button (red/green)
  - Absent in DT: There are 2.4GHz/5.0GHz WiFi status LEDs connected to
      the WiFi chips instead of the SoC.
- NAND flash
- Embedded Ethernet switch
- Factory-programmed Ethernet MAC address

WiFi cannot be enabled at this time due to Linux lacking drivers for
both the PCIe controllers and the PCIe WiFi peripherals.

95d56dfaa0 arm64: dts: broadcom: bcmbca: bcm4908: Protect cpu-release-addr
The `cpu-release-addr` property is relevant only when the "spin-table"
enable method is used. It is the physical address where the bootloader
expects Linux to write the secondary CPU entry point's physical address.
On this platform, only the CFE bootloader uses this method: U-Boot uses
PSCI instead.

CFE actually walks the FDT to learn this address, so we're free to put
it wherever we want. We only need to make sure that it goes in a
reserved-memory block so that writing to it during early boot does not
risk conflicting with an unrelated memory allocation: this was not done.

Since the previous patch reserved the first page of memory for CFE's
secondary-CPU init stub, which is actually much smaller than a page,
just put this address at the end of that page and it shall be so
protected.

cef313931d arm64: dts: broadcom: bcmbca: bcm4908: Reserve CFE stub area
The CFE bootloader places a stub program in the first page of physical
memory to hold the secondary CPUs until the boot CPU writes the release
address, but does not splice a /reserved-memory node into the FDT to
protect it. If Linux overwrites this program before execution reaches
smp_prepare_cpus(), the secondary CPUs may become inaccessible.

This is only a problem with CFE, and then only until the secondary CPUs
are brought online. Ideally, there would be some hypothetical mechanism
we could use to indicate that this area of memory is sensitive only
during boot. But as there is none, and since it is such a small amount
of memory, it is easiest to reserve it unconditionally.

Therefore, add a /reserved-memory node to bcm4908.dtsi to protect the
first 4KiB of physical memory.

058387d9c6 arm64: dts: broadcom: Fix L2 linesize for Raspberry Pi 5
Set the cache-line-size parameter of the L2 cache for each core to the
correct value of 64 bytes.

Previously, the L2 cache line size was incorrectly set to 128 bytes
for the Broadcom BCM2712. This causes validation tests for the
Performance Application Programming Interface (PAPI) tool to fail as
they depend on sysfs accurately reporting cache line sizes.

The correct value of 64 bytes is stated in the official documentation of
the ARM Cortex A-72, which is linked in the comments of
arm64/boot/dts/broadcom/bcm2712.dtsi as the source for cache-line-size.

   - The ssfdc driver received few minor adjustments

   - The usual load of misc/small improvements and fixes

  Raw NAND:

   - The main series brought is an update of the Broadcom support to
     support all BCMBCA SoCs and their specificity (ECC, write
     protection, configuration straps), plus a few misc fixes and
     changes in the main driver. Device tree updates are also part of
     this PR, initially because of a misunderstanding on my side.

   - The STM32_FMC2 controller driver is also upgraded to properly
     support MP1 and MP25 SoCs.

   - A new compatible is added for an Atmel flavor.

   - Among all these feature changes, there is as well a load of
     continuous read related fixes, avoiding more corner conditions and
     clarifying the logic. Finally a few miscellaneous fixes are made to
     the core, the lpx32xx_mlc, fsl_lbc, Meson and Atmel controller
     driver, as well as final one in the Hynix vendor driver.

  SPI-NAND:

   - The ESMT support has been extended to match 5 bytes ID to avoid
     collisions. Winbond support on its side receives support for
     W25N04KV chips.

  SPI NOR:

   - SPI NOR gets the non uniform erase code cleaned. We stopped using
     bitmasks for erase types and flags, and instead introduced
     dedicated members. We then passed the SPI NOR erase map to MTD.
     Users can now determine the erase regions and make informed
     decisions on partitions size.

   - An optional interrupt property is now described in the bindings"

724ba67515 ARM: dts: Move .dts files to vendor sub-directories
The arm dts directory has grown to 1559 boards which makes it a bit
unwieldy to maintain and use. Past attempts stalled out due to plans to
move .dts files out of the kernel tree. Doing that is no longer planned
(any time soon at least), so let's go ahead and group .dts files by
vendors. This move aligns arm with arm64 .dts file structure.

There's no change to dtbs_install as the flat structure is maintained on
install.

The naming of vendor directories is roughly in this order of preference:
- Matching original and current SoC vendor prefix/name (e.g. ti, qcom)
- Current vendor prefix/name if still actively sold (SoCs which have
  been aquired) (e.g. nxp/imx)
- Existing platform name for older platforms not sold/maintained by any
  company (e.g. gemini, nspire)

The whole move was scripted with the exception of MAINTAINERS and a few
makefile fixups.

3cdba279c5 arm64: dts: broadcom: Enable device-tree overlay support for RPi devices
Add the '-@' DTC option for the Raspberry Pi devices. This option
populates the '__symbols__' node that contains all the necessary symbols
for supporting device-tree overlays (for instance from the firmware or
the bootloader) on these devices.

The Rasbperry Pi devices are well known for their GPIO header, that
allow various "HATs" or other modules do be connected and this enables
users to create out-of-tree device-tree overlays for these modules.

Please note that this change does increase the size of the resulting DTB
by ~40%. For example, with v6.4-rc1 increase in size is as follows:

  bcm2711-rpi-400.dtb       27556 -> 38141 bytes
  bcm2711-rpi-4-b.dtb       27484 -> 38069 bytes
  bcm2711-rpi-cm4-io.dtb    27373 -> 38076 bytes
  bcm2837-rpi-3-a-plus.dtb  14930 -> 20713 bytes
  bcm2837-rpi-3-b.dtb       15107 -> 20979 bytes
  bcm2837-rpi-3-b-plus.dtb  15463 -> 21443 bytes
  bcm2837-rpi-cm3-io3.dtb   14429 -> 20098 bytes
