There is a newer version of this series
[PATCH net-next v2 4/5] net: phy: mediatek: Integrate read/write page helper functions
Posted by Sky Huang 2 weeks, 4 days ago 
From: "SkyLake.Huang" <skylake.huang@mediatek.com>

This patch integrates read/write page helper functions as MTK phy lib.
They are basically the same in mtk-ge.c & mtk-ge-soc.c.
