[PATCH 2/7] clk: mediatek: reset: Rename reset function
Rex-BC Chen
rex-bc.chen at mediatek.com
Mon Apr 18 06:21:49 PDT 2022
There are two version for clock reset register control of MediaTek SoCs.
Since MT8183, the version 2 is adopted.
To make the driver more readable,
- Rename them to v2 for MT8183 and v1 for previous SoCs.
- Adjust the fuinction order in reset.c.
