babe393974 The number of commits for documentation is not huge this time around, but 
there are some significant changes nonetheless:
 
 - Some more Spanish-language and Chinese translations.
 
 - The much-discussed documentation of the confidential-computing threat
   model.
 
 - Powerpc and RISCV documentation move under Documentation/arch - these
   complete this particular bit of documentation churn.

385903a7ec SoC driver updates for 6.7 
The highlights for the driver support this time are
 
  - Qualcomm platforms gain support for the Qualcomm Secure Execution
    Environment firmware interface to access EFI variables on certain
    devices, and new features for multiple platform and firmware drivers.
 
  - Arm FF-A firmware support gains support for v1.1 specification features,
    in particular notification and memory transaction descriptor changes.
 
  - SCMI firmware support now support v3.2 features for clock and DVFS
    configuration and a new transport for Qualcomm platforms.
 
  - Minor cleanups and bugfixes are added to pretty much all the active
    platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
    atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
    In particular, this contains portions of the treewide conversion to
    use __counted_by annotations and the device_get_match_data helper.

    including size computation (Rafael Wysocki).
 
  - Clean up ACPI utilities code so as to make it follow the kernel
    coding style (Jonathan Bergh).
 
  - Consolidate IRQ trigger-type override DMI tables and drop .ident
    values from dmi_system_id tables used for ACPI resources management
    quirks (Hans de Goede).

  - Allow _DSD buffer data only for byte accessors and document the _DSD
    data buffer GUID (Andy Shevchenko).
 
  - Drop BayTrail and Lynxpoint pinctrl device IDs from the ACPI LPSS
    driver, because it does not need them (Raag Jadav).

Pull ACPI updates from Rafael Wysocki:
 "These fix issues, add new quirks, rearrange the IRQ override quirk
  definitions, add new helpers and switch over code to using them,
  rework a couple of interfaces to be more flexible, eliminate strncpy()
  usage from PNP, extend the ACPI PCC mailbox driver and clean up code.

  This is based on ACPI thermal driver changes that are present in the
  thermal control updates for 6.7-rc1 pull request (they are depended on
  by the ACPI utilities updates). However, the ACPI thermal driver
  changes are not included in the list of specific ACPI changes below.

Last user of those macros were fixed by commit 5e6cb39a25 ("net:

57e06f8c1f Qualcomm driver updates for v6.7 
This introduces partial support for the Qualcomm Secure Execution
 Environment SCM interface, and uses this to implement EFI variable
 access on the Windows On Snapdragon devices (for now).
 
 The 32/64-bit calling convention detector of the SCM interface is
 updated to not choose 64-bit convention when Linux is 32-bit. The
 "extern" specifier is dropped from the interface include file.
 
 The LLCC driver gains support for carrying configuration for multiple
 different system/DDR configurations for a given platform, and selecting
 between them. Support for Q[DR]U1000 is added to the driver.
 
 All exported symbols are transitioned to EXPORT_SYMBOL_GPL().
 
 The platform_drivers in the Qualcomm SoC are transitioned to the
 void-returning remove_new implementation.
 
 The rmtfs memory driver gains support for leaving guard pages around the
 used area, to avoid issues if the allocation happens to be placed
 adjacent to another protected memory region.
 
 The socinfo driver gains knowledge about IPQ8174, QCM6490, SM7150P and
 various PMICs used together with SM8550.

09427e1975 RISC-V SoC drivers for v6.7 
Minor changes here only. There's the treewide remove callback work from
 Uwe, some of my own gradual conversion of SOC_ Kconfig options and a
 selection of the ARM AMBA protocol required for the crypto driver on
 StarFive JH7110 SoCs. The latter was supposed to be in v6.6, but I
 forgot to send a PR.

ba21d6367c soc: qcom: apr: Add __counted_by for struct apr_rx_buf and use struct_size() 
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.

This code was found with the help of Coccinelle, and audited and
fixed manually.

f86955f2b1 soc: qcom: pmic_glink: fix connector type to be DisplayPort 
As it was pointed out by Simon Ser, the DRM_MODE_CONNECTOR_USB connector
is reserved for the GUD devices. Other drivers (i915, amdgpu) use
DRM_MODE_CONNECTOR_DisplayPort even if the DP stream is handled by the
USB-C altmode. While we are still working on implementing the proper way
to let userspace know that the DP is wrapped into USB-C, change
connector type to be DRM_MODE_CONNECTOR_DisplayPort.

db758b73f8 soc/loongson: loongson2_guts: Convert to platform remove callback returning void 
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

AngeloGioacchino Del Regno is stepping in as co-maintainer for the
 MediaTek SoC platform and starts by sending some dts fixes for
 the mt8195 platform that had been pending for a while.
 
 On the ixp4xx platform, Krzysztof Halasa steps down as co-maintainer,
 reflecting that Linus Walleij has been handling this on his own
 for the past few years.
 
 Generic RISC-V kernels are now marked as incompatible with the
 RZ/Five platform that requires custom hacks both for managing
 its DMA bounce buffers and for addressing low virtual memory.
 
 Finally, there is one bugfix for the AMDTEE firmware driver
 to prevent a use-after-free bug.

1531309aa2 soc: renesas: Make ARCH_R9A07G043 depend on required options 
Randy reported a randconfig build issue against linux-next:

    WARNING: unmet direct dependencies detected for ERRATA_ANDES
      Depends on [n]: RISCV_ALTERNATIVE [=n] && RISCV_SBI [=y]
      Selected by [y]:
      - ARCH_R9A07G043 [=y] && SOC_RENESAS [=y] && RISCV [=y] && NONPORTABLE [=y] && RISCV_SBI [=y]

       59 | void __init_or_module andes_errata_patch_func(struct alt_entry *begin, struct alt_entry *end,

On RISC-V, alternatives are not usable in XIP kernels, which this
randconfig happened to select.  Rather than add a check for whether
alternatives are available before selecting the ERRATA_ANDES config
option, rework the R9A07G043 Kconfig entry to depend on the
configuration options required to support its non-standard cache
coherency implementation.

Without these options enabled, the SoC is effectively non-functional to
begin with, so there's an extra benefit in preventing the creation of
non-functional kernels.

The "if RISCV_DMA_NONCOHERENT" can be dropped, as ERRATA_ANDES_CMO will
select it.

c1ec4b450a soc: renesas: Make ARCH_R9A07G043 (riscv version) depend on NONPORTABLE 
Drew found "CONFIG_DMA_GLOBAL_POOL=y causes ADMA buffer alloc to fail"
the log looks like:

    mmc0: Unable to allocate ADMA buffers - falling back to standard DMA

The logic is: generic riscv defconfig selects ARCH_RENESAS then
ARCH_R9A07G043 which selects DMA_GLOBAL_POOL, which assumes all
non-dma-coherent riscv platforms have a dma global pool, this assumption
seems not correct. And I believe DMA_GLOBAL_POOL should not be
selected by ARCH_SOCFAMILIY, instead, only ARCH under some specific
conditions can select it globaly, for example NOMMU ARM and so on,
because it's designed for special cases such as "nommu cases where
non-cacheable memory lives in a fixed place in the physical address
map" as pointed out by Robin.

Fix the issue by making ARCH_R9A07G043 (riscv version) depend on
NONPORTABLE, thus generic defconfig won't select ARCH_R9A07G043 by
default. And even for random config case, there will be less debug
effort once we see NONPORTABLE is enabled.
