Hello all,
This series adds support for the Microchip Inter-Processor Communication
(IPC) remoteproc platform driver.
Microchip's family of RISC-V SoCs typically has one or more clusters
that can be configured to run in Asymmetric Multi-Processing (AMP) mode.
The IPC remoteproc platform driver allows for starting and stopping
firmware on the remote cluster(s) and facilitates RPMsg communication.
The remoteproc attach/detach operations are also supported for use cases
where the firmware is loaded by the Hart Software Services
(zero-stage bootloader) before Linux boots.
Error Recovery and Power Management features are not currently
supported in the remoteproc platform driver.
Changes in v2:
- simplify memory region handling with memory-region-names
- rename compatible to "microchip,ipc-sbi-remoteproc"
- rephrase dt binding commit subject, message and description property
- drop microchip,auto-boot and microchip,skip-ready-wait properties
- fix memory-region constraints and add memory-region-names
- fix binding example and add examples for all use cases
- Link to v1: https://patchwork.kernel.org/project/linux-remoteproc/pat...
Thanks,
Valentina
