STM32MP157F-DK2 board embeds a STM32MP157F SoC. This SoC contains the same level of feature than a STM32MP157C SOC but A7 clock frequency can reach 800MHz, hence the inclusion of the newly introduced stm32mp15xf.dtsi. As for other latest STM32 MPU families, STM32MP157F-DK2 relies on OP-TEE SCMI services for SoC clock and reset controllers resources, and for PMIC, now under OP-TEE control. That's why stm32mp157f-dk2-scmi.dtsi is introduced, to move all clocks, resets and regulators to SCMI-based ones. To "disable" SCMI, just need to comment stm32mp157f-dk2-scmi.dtsi inclusion and to replace &scmi_v3v3 with &v3v3, then to disable arm_wdt and to enable i2c4 and its subnodes for PMIC support by Linux. Reconfigure usbotg for dual role with type-C support if needed.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
