Subject: [RFC PATCH 7/7] ARM: dts: stm32: add ETZPC as a system bus for STM32MP13x boards
The STM32 System Bus is an internal bus on which devices are connected.
ETZPC is a peripheral overseeing the firewall bus that configures
and control access to the peripherals connected on it.
For more information on which peripheral is securable, please read
the STM32MP13 reference manual.
