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.
* 'cznic/platform' of https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc:
platform: cznic: use ffs() instead of __bf_shf()
firmware: turris-mox-rwtm: fix building without CONFIG_KEYS
platform: cznic: fix function parameter names
firmware: turris-mox-rwtm: Add support for ECDSA signatures with HW private key
firmware: turris-mox-rwtm: Drop ECDSA signatures via debugfs
platform: cznic: turris-omnia-mcu: Add support for digital message signing with HW private key
platform: cznic: Add keyctl helpers for Turris platform
platform: cznic: turris-omnia-mcu: Refactor requesting MCU interrupt
