STMicrolectronics STM32MP157 MPU are based on a Dual Arm Cortex-A7 core and a
Cortex-M4.
This patchset adds the support of the stm32_rproc driver allowing to control
the M4 remote processor.
Changes since v3:
-Replaced "st,auto_boot" with "st,auto-boot"
-Update m4 reg values and align with unit-address
Changes since v2:
- Clarified "reg" description
- Change m4 unit adress to 38000000
- Renamed "auto_boot" in "st,auto-boot"
Changes since v1:
- Gave details about the memory mapping (in bindings).
- Used 'dma-ranges' instead of 'ranges'.
- Updated the 'compatible' property.
- Remove the 'recovery', 'reset-names' and 'interrupt-names' properties.
- Clarified why / when mailboxes are optional.
