The STMicroelectronics STM32 Inter-Processor Communication Controller
(IPCC) is used for communicating data between two processors.
It provides a non blocking signaling mechanism to post and retrieve
communication data in an atomic way.
Changes since v2:
- update bindings and driver according to Rob's comments:
- change compatible property to "st,stm32mp1-ipcc"
- change "st,proc_id" property to "st,proc-id"
- define all interrupts as mandatory
