<br />
== Article purpose ==<br />
The purpose of this article is to explain how to configure the ''CRYP''<ref name="CRYP internal peripheral"> [[CRYP internal peripheral]] </ref> ''' when the peripheral is assigned to Linux<sup>&reg;</sup> OS'''. <br />
<br />
The configuration is performed using the '''device tree mechanism'''<ref> [[Device tree]]</ref>.<br />
<br />
The [[Device tree]] provides a hardware description of the ''CRYP''<ref name="CRYP internal peripheral"/>, used by STM32 ''CRYP Linux driver''.<br />
<br />
== DT bindings documentation ==<br />
The ''CRYP'' <ref name="CRYP internal peripheral"/> is represented by the ''STM32 CRYP device tree bindings''<ref>{{CodeSource | Linux kernel | Documentation/devicetree/bindings/crypto/st,stm32-cryp.txt | Documentation/devicetree/bindings/crypto/st,stm32-cryp.txt}}</ref>.<br />
<br />
== DT configuration ==<br />
This hardware description is a combination of STM32 microprocessor and board device tree files. See [[Device tree]] for explanations on device tree file split.<br />
<br />
The '''STM32CubeMX''' can be used to generate the board device tree. Refer to [[#How_to_configure_the_DT_using_STM32CubeMX]] for more details.<br />
<br />
===DT configuration (STM32 level) ===<br />
The CRYP node is declared in stm32mp157c.dtsi<ref name="stm32mp157c_dtsi">{{CodeSource | Linux kernel | arch/arm/boot/dts/stm32mp157c.dtsi | STM32MP157C device tree file}}</ref>. It provides the hardware registers base address, clock, interrupt and reset.<br />
<br />
cryp1: cryp@54001000 {<br />
compatible = "st,stm32mp1-cryp";<br />
reg = <0x54001000 0x400>;<br />
interrupts = <GIC_SPI 79 IRQ_TYPE_LEVEL_HIGH>;<br />
clocks = <&rcc CRYP1>;<br />
resets = <&rcc CRYP1_R>;<br />
status = "disabled";<br />
};<br />
<br />
{{Warning|This device tree part is related to STM32 microprocessors. It should be kept as is, without being modified by the end-user.}}<br />
<br />
=== DT configuration (board level) ===<br />
This part is used to enable the CRYP used on a board. This is done by setting the '''status''' property to '''okay'''.<br />
<br />
=== DT configuration examples ===<br />
&cryp1 {<br />
status = "okay";<br />
};<br />
<br />
==How to configure the DT using STM32CubeMX==<br />
The [[STM32CubeMX]] tool can be used to configure the STM32MPU device and get the corresponding [[Device_tree#STM32|platform configuration device tree]] files.<br /><br />
The STM32CubeMX may not support all the properties described in the above [[#DT bindings documentation|DT bindings documentation]] paragraph. If so, the tool inserts '''user sections''' in the generated device tree. These sections can then be edited to add some properties and they are preserved from one generation to another. Refer to [[STM32CubeMX]] user manual for further information.<br />
