1. Article purpose[edit source]
The purpose of this article is to explain how to configure the PKA internal peripheral using the device tree mechanism.
2. DT bindings documentation[edit source]
The following binding-related documentation explains how to write device tree files for PKA:
- OP-TEE STM32 PKA device tree bindings: documentation/devicetree/bindings/crypto/st,stm32-pka.yaml[1].
3. DT configuration[edit source]
This hardware description is a combination of STM32 microprocessor and board device tree files. See Device tree for explanations on device tree file split.
3.1. DT configuration (STM32 level)[edit source]
The PKA node is located in the STM32 MPU device tree.
3.2. DT configuration (board level)[edit source]
Board level device tree is used to enable the PKA.
