Subject: [PATCH v3 0/8] stm32 m4 remoteproc on STM32MP157c

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 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.

Fabien Dessenne (8):
  dt-bindings: stm32: add bindings for ML-AHB interconnect
  dt-bindings: remoteproc: add bindings for stm32 remote processor
    driver
  remoteproc: stm32: add an ST stm32_rproc driver
  ARM: dts: stm32: add m4 remoteproc support on STM32MP157c
  ARM: dts: stm32: declare copro reserved memories on STM32MP157c-ed1
  ARM: dts: stm32: enable m4 coprocessor support on STM32MP157c-ed1
  ARM: dts: stm32: declare copro reserved memories on STM32MP157a-dk1
  ARM: dts: stm32: enable m4 coprocessor support on STM32MP157a-dk1
