This is something commonly asked by Linux kernel DT maintainers [1].
The mentioned doc is not upstreamed, but may be checked with dtbs_check.
While at it align some nodes with Linux or OP-TEE.

The RCC security is managed with a dedicated compatible:
"st,stm32mp1-rcc-secure" [1].
Remove useless secure-status property in boards rcc nodes.

With recent changes, TF-A now panics on MC-1, Avenger96 and Odyssey:
NOTICE: CPU: STM32MP157C?? Rev.B
NOTICE: Model: Linux Automation MC-1 board
ERROR: regul ldo3: max value 750 is invalid
PANIC at PC : 0x2ffeebb7
as the driver takes great offense at the content of the device
tree. The parts in question were copy-pasted from ST DTs, but
those ST DTs were fixed by commit 67d95409ba
("refactor(stm32mp1-fdts): update regulator description").
Fix the breakage by transplanting the same changes into all
remaining STM32MP1 DTs.
Change was boot-tested on MC-1, but only build tested for the
other two.

Seeed Studio’s SoM‐STM32MP157C is a System‐on‐Module that integrates the
STM32MP157C MPU (the 650 MHz dual‐core variant with a GPU and a
cryptographic processor) the STPMIC1A PMIC, 512 MB of DDR3 RAM and a
4 GB eMMC. There are two LEDs as well, one hardwired to the PMIC’s VDD
output, and the other available at the MPU’s port PG3. The SoM can be
plugged into a carrier board using its three 70‑pin connectors.
Seeed Odyssey‐STM32MP157C is the reference carrier board for the SoM in
a Raspberry Pi‐like form factor. It features a WiFi/Bluetooth chip, a
microSD card port and various I/O interfaces.
The device tree is based on the DKx boards. TF‑A was successfully tested
on the board with Buildroot 2021.02 and U-Boot 2021.04.
