ST's platforms often have multiple co-processors (usually ST40s or ST231s) on-board. This provides the Linux-side infrastructure to flash and boot them successfully. This set has been tested on an STiH410-B2120. v3 => v4: Suggested-by: Suman Anna <s-anna@xxxxxx> - Move to using 'reserved-memory' API - New 'reserved-memory' nodes - Remove memory locations from RemoteProc's DT node's reg properties - Remove C code obtaining/allocating DMA memory - Re-order .start() and .stop() ops - Add protection around Reset API in error path - Explicitly set .has_iommu to false v2 => v3: - Generify syscon property (st,syscfg-boot => st,syscfg) - Rename IP in DT bindings doc (Remote Processor => Co-Processor) - Remove superfluous 'clock-names' property - Remove superfluous 'reg-names' property - Populate MAINTAINERS - Clean-up DTS formatting - Use strings in debugfs to control procs ('1|0' => 'start|stop') - Align copyright statement with MODULE() macros - Rename driver data structure ('st_rproc' => 'ddata') - Addition of a full error path in .start() v1 => v2: - Remove Linux implementation specific comment from binding document - Force debugfs '0' to shutdown co-processor - rather than !1 - Supply more detailed commit message - Propagate errors back from .stop() - Review GPL wording - Supply original author's SoBs Lee Jones (6): remoteproc: dt: Provide bindings for ST's Remote Processor Controller driver remoteproc: debugfs: Add ability to boot remote processor using debugfs remoteproc: Supply controller driver for ST's Remote Processors MAINTAINERS: Add ST's Remote Processor Driver to ARM/STI ARCHITECTURE ARM: STiH407: Add nodes for RemoteProc ARM: STiH407: Move over to using the 'reserved-memory' API for obtaining DMA memory .../devicetree/bindings/remoteproc/st-rproc.txt | 41 +++ MAINTAINERS | 1 + arch/arm/boot/dts/stih407-family.dtsi | 70 +++++ drivers/remoteproc/Kconfig | 9 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/remoteproc_debugfs.c | 34 +++ drivers/remoteproc/st_remoteproc.c | 297 +++++++++++++++++++++ 7 files changed, 453 insertions(+) create mode 100644 Documentation/devicetree/bindings/remoteproc/st-rproc.txt create mode 100644 drivers/remoteproc/st_remoteproc.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
