15 Say yes here to add support for the MediaTek Command Queue (CMDQ)
16 driver. The CMDQ is used to help read/write registers with critical
17 time limitation, such as updating display configuration during the

22 help
23 Say yes here to enable support for Mediatek Device APC driver.
24 This driver is mainly used to handle the violation which catches
25 unexpected transaction.
26 The violation information is logged for further analysis or
27 countermeasures.

32 help
33 Say yes here to add support for the MediaTek Dynamic Voltage
34 and Frequency Scaling Resource Collector (DVFSRC): a HW
35 IP found on many MediaTek SoCs, which is responsible for
36 collecting DVFS requests from various SoC IPs, other than
37 software, and performing bandwidth scaling to provide the
38 best achievable performance-per-watt.

75 help
76 The Smart Voltage Scaling(SVS) engine is a piece of hardware
77 which has several controllers(banks) for calculating suitable
78 voltage to different power domains(CPU/GPU/CCI) according to
79 chip process corner, temperatures and other factors. Then DVFS
80 driver could apply SVS bank voltage to PMIC/Buck.
