This series enables the support for SA8255p Qualcomm SoC and Ride
platform. This platform uses SCMI power, reset, performance, sensor
protocols for resources(e.g. clocks, regulator, interconnect, phy etc.)
management. SA8255p is a virtual platforms that uses Qualcomm smc/hvc
transport driver.
Multiple virtual SCMI instances are being used to achieve the parallelism.
SCMI platform stack runs in SMP enabled VM hence allows platform to service
multiple resource requests in parallel. Each device is assigned its own
dedicated SCMI channel and Tx/Rx doorbells.
Resource operations are grouped together to achieve better abstraction
and to reduce the number of requests being sent to SCMI platform(server)
thus improving boot time KPIs. This design approach was presented during
LinaroConnect 2024 conference[1].
