[PATCH v8 13/13] ARM: dts: stm32: put ETZPC as an access controller for STM32MP13x boards

Gatien Chevallier
2023-12-12T15:28:10Z

Reference ETZPC as an access-control-provider.

For more information on which peripheral is securable or supports MCU
isolation, please read the STM32MP13 reference manual
