Pull SoC driver updates from Arnd Bergmann:
"Updates are across the usual driver subsystems with SoC specific
drivers:

- added soc specicific drivers for sophgo cv1800 and sg2044, qualcomm
sm8750, and amlogic c3 and s4 chips.

- cache controller updates for sifive chips, plus binding changes for
other cache descriptions.

- memory controller drivers for mediatek mt6893, stm32 and cleanups
for a few more drivers

- reset controller drivers for T-Head TH1502, Sophgo sg2044 and
Renesas RZ/V2H(P)

- SCMI firmware updates to better deal with buggy firmware, plus
better support for Qualcomm X1E and NXP i.MX specific interfaces

- a new platform driver for the crypto firmware on Cznic Turris
Omnia/MOX

- cleanups for the TEE firmware subsystem and amdtee driver

- minor updates and fixes for freescale/nxp, qualcomm, google,
aspeed, wondermedia, ti, nxp, renesas, hisilicon, mediatek,
broadcom and samsung SoCs"

Merge branch 'cznic/platform' of https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc into soc/drivers

These are updates from Marek Behún for the cznic platform drivers:

This series adds support for generating ECDSA signatures with hardware
stored private key on Turris Omnia and Turris MOX.
This ability is exposed via the keyctl() syscall.

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
