This patchset adds below DSP FastRPC features that have been missing in upstream fastrpc driver and also cleans up channel context structure with kref.
- Add ablity to reflect if the DSP domain is secure/unsecure by creating seperate device nodes for secured domain, this would used by SE policy to restrict applications loading process on the DSP. - Add new IOCTL to get DSP capabilites - Add IOCTL to support mapping memory on the DSP.
Tested this series on DragonBoard 845c with TensorFlow.
