This provides the Linux-side infrastructure to flash and boot them successfully. This set has been tested on an STiH410-B2120. v2 => v3: - Generify syscon property (st,syscfg-boot => st,syscfg-boot) - 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 (4): ARM: STiH407: Add nodes for RemoteProc remoteproc: dt: Provide bindings for ST's Remote Processor Controller driver remoteproc: Supply controller driver for ST's Remote Processors remoteproc: debugfs: Add ability to boot remote processor using debugfs Lee Jones (6): ARM: STi: Add DT defines for co-processor reset lines remoteproc: dt: Provide bindings for ST's Remote Processor Controller driver remoteproc: Supply controller driver for ST's Remote Processors remoteproc: debugfs: Add ability to boot remote processor using debugfs ARM: STiH407: Add nodes for RemoteProc MAINTAINERS: Add ST's Remote Processor Driver to ARM/STI ARCHITECTURE .../devicetree/bindings/remoteproc/st-rproc.txt | 35 +++ MAINTAINERS | 1 + arch/arm/boot/dts/stih407-family.dtsi | 40 +++ drivers/remoteproc/Kconfig | 9 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/remoteproc_debugfs.c | 34 +++ drivers/remoteproc/st_remoteproc.c | 307 +++++++++++++++++++++ .../dt-bindings/reset-controller/stih407-resets.h | 4 + 8 files changed, 431 insertions(+) create mode 100644 Documentation/devicetree/bindings/remoteproc/st-rproc.txt create mode 100644 drivers/remoteproc/st_remoteproc.c -- 1.9.1
