[PATCH v17 0/7] soc: mediatek: SVS: introduce MTK SVS

From: Roger Lu
Date: Tue May 18 2021 - 01:19:06 EST

1. SVS driver uses OPP adjust event in [1] to update OPP table voltage part.
2. SVS driver gets thermal/GPU device by node [2][3] and CPU device by get_cpu_device().
After retrieving subsys device, SVS driver calls device_link_add() to make sure probe/suspend callback priority.
3. SVS dts refers to reset controller [4] to help reset SVS HW.

changes since v16:
- Specify IRQF_ONESHOT directly when requesting the
interrupt (because it is always needed, no matter which SOC)
