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/patch/[email protected]/ Thanks, Valentina Valentina Fernandez (2): dt-bindings: remoteproc: add Microchip IPC remoteproc remoteproc: add support for Microchip IPC remoteproc platform driver .../microchip,ipc-sbi-remoteproc.yaml | 95 ++++ drivers/remoteproc/Kconfig | 12 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/mchp_ipc_sbi_remoteproc.c | 465 ++++++++++++++++++ 4 files changed, 573 insertions(+) create mode 100644 Documentation/devicetree/bindings/remoteproc/microchip,ipc-sbi-remoteproc.yaml create mode 100644 drivers/remoteproc/mchp_ipc_sbi_remoteproc.c -- 2.34.1
