[PATCH v4 0/2] mailbox: introduce STMicroelectronics STM32 IPCC driver

[Fabien Dessenne]

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 v4:
- add Rob's 'Reviewed-by' in dt bindings

Changes since v3:
- update after Jassi Brar review: remove 'driver.owner'

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
