preparation for a new implementation via the keyctl() syscall.

df94a2f1eb platform: cznic: turris-omnia-mcu: Add support for digital message signing with HW private key
Add support for digital message signing with the private key stored in
the MCU. Turris Omnia boards with MKL MCUs have a NIST256p ECDSA private
key generated and burned into MCU's flash when manufactured. The private
key is not readable from the MCU, but MCU allows for signing messages
with it and retrieving the public key.

This is exposed to userspace via the keyctl API.

In userspace, the user can look at /proc/keys or list the keyring:

  $ cat /proc/keys
  0a3b7cd3 ... keyring   .turris-signing-keys: 1
  3caf0b1a ... turris-om Turris Omnia SN 0000000A1000023 MCU ECDSA k...

  $ keyctl rlist %:.turris-signing-keys
  1018104602

To get the public key:

  $ keyctl read 1018104602
  33 bytes of data in key:
  025d9108 1fb538ae 8435c88b b4379171 d6b158a9 55751b91 1d23e6a9 d017f4b2
  1c

To sign a message:

  $ dd if=/dev/urandom of=msg_to_sign bs=32 count=1
  $ keyctl pkey_sign 1018104602 0 msg_to_sign >signature

0b28b7080e platform: cznic: Add keyctl helpers for Turris platform
Some Turris devices support signing messages with a per-device unique
asymmetric key that was created on the device at manufacture time.

Add helper module that helps to expose this ability via the keyctl()
syscall.

A device-specific driver can register a signing key by calling
devm_turris_signing_key_create().

Both the `.turris-signing-keys` keyring and the signing key are created
with only the VIEW, READ and SEARCH permissions for userspace - it is
impossible to link / unlink / move them, set their attributes, or unlink
the keyring from userspace.

enable the serial node while keeping second - I2C - disabled.

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read.  Ternary
   operator has three arguments and with wrapping might lead to quite
   long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary

MediaTek driver	updates for v6.15

This adds entries for new and missing SoCs in the MediaTek SoCInfo
driver (MT8370AV/AZA, MT8390AV/AZA) and	an extra entry for a new
revision of the	MT8395AV/ZA SoC.

The MediaTek SoCInfo driver also gets its SoC attribute	information
restructured: now the family, machine and soc_id fields are correctly
populated.

MT8188 gains support for the secondary Display Parallel Interface
used for HDMI, and for the Display Stream Compression component
routing through mmsys and mutex tables.

All of the MMSYS drivers get an important overhaul: it was found that,
in multiple cases, the tables contained wrong mask/value pairs, hence
those were doing either nothing or breaking routings.
The mmsys tables were converted to use a newly introduced macro that
will perform a compile time check, making sure that each table entry's
value fits in the declared register mask.

Thanks to the new macro, multiple MediaTek SoCs got multiple fixes in
their MMSYS tables, addressing issues that were severely impacting the
functionality of the display controller pipelines.

The scmi_common_fastchannel_db_ring() function calls either ioread64()

The same logic is used to define ioread64() itself in the

is not really needed.

Arm FF-A updates for v6.15

This update primarily focuses on FF-A framework notification support
along with other improvements, including UUID handling enhancements
and various fixes.

1. FF-A framework notification upport

    - Adds support for multiple UUIDs per partition to register individual
      SRI callbacks.
    - Handles Rx buffer full framework notifications and provides a general
      interface for future extensions.

2. Improved multiple UUID/services per-partition handling

    - Adds support for UUID passing in FFA_MSG_SEND2, improving multiple
      UUID/service support in the driver.
    - Introduces a helper function to check whether a partition can
      receive REQUEST2 messages.

3. Partition handling generic improvements

    - Implements device unregistration for better partition cleanup.
    - Improves handling of the host partition presence in partition info.

4. FF-A version updates

    - Upgrades the driver version to FF-A v1.2.
    - Rejects major versions higher than the driver version as incompatible.

5. Big-Endian support fixes

    - Fixes big-endian issues in:
        __ffa_partition_info_regs_get()
        __ffa_partition_info_get()
    - Big-endian support is still incomplete, and only these changes can
      be verified without additional application/testing updates at the
      moment. We can discover all the partitions correctly with big-endian
      kernel now.

6. Miscellaneous fixes

    - Fixes function prototype misalignments in: sync_send_receive{,2}
    - Adds explicit type casting for return values from: FFA_VERSION
      and NOTIFICATION_INFO_GET
    - Corrects vCPU list parsing in ffa_notification_info_get().

7. UUID management in the driver and DMA mask updates

    - Replaces UUID buffer with the standard UUID format in ffa_partition_info
      structure.
    - Fixes a typo in some FF-A bus macros.
    - Sets dma_mask for FF-A devices.

In short, this update enhances notification handling, UUID support, and
overall robustness of the FF-A driver while addressing multiple fixes
and cleanups.

Arm SCMI updates for v6.15

Couple of updates around the flexibility in SCMI device names and
addition of name, protocol id attributes and modalias for SCMI
devices in the sysfs.

Currently, in the scmi_protocol_device_request() function, SCMI device
names ust be unique across all protocols. However, this constraint is
being relaxed, allowing devices in different protocols to share the
same name. The change aims to provide more flexibility in naming devices
across various protocols.

Two attributes: name and protocol ID is being added to the SCMI device
in the sysfs along with the support for the modalias. These attributes
aim to enhance device identification and management.

Arm SMCCC update for v6.15

Just a single update introducing the support for the optional SOC_ID
name string from the Arm SMCCC v1.6 specification.

If the SOC_ID name string is implemented, the machine field of the SoC
Device Attributes will reflect it.

The original intent of SOC_ID was to provide a JEP-106 code for the SiP
and the SoC revision to uniquely identify the SoC. However, there has
been a request to add this optional name so that SoC firmware can
directly provide the SoC name to the OS.

This change avoids the need for frequent updates to various tools that
would otherwise require maintaining hardcoded model/machine name tables
for new SoCs.

d294d56cb9 soc: mediatek: mt8365-mmsys: Fix routing table masks and values
The mmsys driver reads the routing table and writes to the
hardware `val & mask`, but multiple entries in the mmsys
routing table for the MT8365 SoC are setting a 0x0 mask:
this effectively writes .. nothing .. to the hardware.

That would never work, and if the display controller was
actually working with the mmsys doing no routing at all,
that was only because the bootloader was correctly setting
the display controller routing registers before booting the
kernel, and the mmsys was never reset.

Make this table to actually set the routing by adding the
correct register masks to it.

While at it, also change MOUT val definitions to BIT(x), as
the MOUT registers are effectively checking for each bit to
enable output to the corresponding HW.
Please note that, for this SoC, only the MOUT registers are
checking bits (as those can enable multiple outputs), while
the others are purely reading a number to select an input.

854ac9c888 soc: mediatek: mtk-mmsys: Add compile time check for mmsys routes
Every MediaTek SoC with multimedia capabilities has an array of
structure mtk_mmsys_routes that defines a multimedia connection
between hardware components.

This connection is activated by writing a (masked) value in each
specific register, and the association between from->to path and
value to write is expressed as an entry in that array.

Failing to set the right path does not give any meaningful error
and makes things to simply not work as the data will either not
be retrieved from the right input port, or will be written to
the wrong output port (or both): since a misconfiguration may
effectively still be a possibly correct configuration at the HW
level, this may be only giving side effects in terms of simply
getting no functionality but, again, no errors.

In order to reduce room for mistakes in declarations of the
mmsys routes, add a macro that compile-time checks that the
provided value does at least fit in the register mask.
