The Qualcomm automotive SA8255p SoC relies on firmware to configure
platform resources, including clocks, interconnects and TLMM. The device
drivers request resources operations over SCMI using power and
performance protocols.

The SCMI power protocol enables or disables resources like clocks,
interconnect paths, and TLMM (GPIOs) using runtime PM framework APIs,
such as resume/suspend, to control power states(on/off).

The SCMI performance protocol manages UART baud rates, with each baud
rate represented by a performance level. Drivers use the
dev_pm_opp_set_level() API to request the desired baud rate by
specifying the performance level.

The QUP drivers are SCMI clients, with clocks, interconnects, pinctrl
and power-domains abstracted by a SCMI server.
