Subject: [PATCH v4 0/6] remoteproc: Add driver for STMicroelectronics platforms
Date: Wed, 21 Oct 2015 12:47:01 +0100 [thread overview]
Message-ID: <1445428027-26174-1-git-send-email-lee.jones@linaro.org> (raw)
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-l0cyMroinI0@public.gmane.org>
- 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
