The MediaTek Ethernet PHY drivers are going to be used by multiple targets (airoha, mediatek, ramips). Add generic backports of changes required for recently added Ethernet PHYs. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

Subject: [PATCH 07/20] net: phy: mediatek: Integrate read/write page helper
|
|
functions
|
|
|
|
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.
