Subject: [PATCH v5 0/2] Add qcom smc/hvc transport support
This change augments smc transport to include support for Qualcomm virtual
platforms by passing a parameter(capability-id) in the hypervisor call to
identify which doorbell to assert. This parameter is dynamically generated
at runtime on the device and insuitable to pass via the devicetree.
The capability-id is stored by firmware in the shmem region.
This has been tested on ARM64 virtual Qualcomm platform.
---
v5 -> changed compatible, removed polling support patch,
make use of smc-id binding for function-id
v4 -> port the changes into smc.c
v3 -> fix the compilation error reported by the test bot,
add support for polling based instances
v2 -> use allOf construct in dtb schema,
remove wrappers from mutexes,
use architecture independent channel layout
v1 -> original patches
