Subject: [PATCH net-next v10 06/13] net: phy: mediatek: Hook LED helper functions in mtk-ge.c
From: "SkyLake.Huang" <skylake.huang@...iatek.com>
We have mtk-phy-lib.c now so that we can use LED helper functions in
mtk-ge.c(mt7531 part). It also means that mt7531/mt7981/mt7988's
Giga ethernet phys share almost the same HW LED controller design.
Also, add probe function for mt7531 so that it can initialize LED state.
Signed-off-by: SkyLake.Huang <skylake.huang@...iatek.com>
---
Changes in v9:
- Led number checking & delay settings are integrated into common code, so
just use it.
