[PATCH 03/12] dt-bindings: display: st,stm32mp25-lvds: add access-controllers property
Posted by Raphael Gallais-Pou 2 months, 1 week ago
access-controllers is an optional property that allows a peripheral to
refer to one or more domain access controller(s).

This property is added when the peripheral is under the STM32 firewall
controller.  It allows an accurate representation of the hardware, where
the peripheral is connected to a firewall bus.  The firewall can then
check the peripheral accesses before allowing its device to probe.
