Subject: [PATCH net-next v6 1/5] net: phy: mediatek: Re-organize MediaTek ethernet phy drivers
From: "SkyLake.Huang" <skylake.huang@...iatek.com>
Re-organize MediaTek ethernet phy driver files and get ready to integrate
some common functions and add new 2.5G phy driver.
mtk-ge.c: MT7530 Gphy on MT7621 & MT7531 Gphy
mtk-ge-soc.c: Built-in Gphy on MT7981 & Built-in switch Gphy on MT7988
mtk-2p5ge.c: Planned for built-in 2.5G phy on MT7988
Signed-off-by: SkyLake.Huang <skylake.huang@...iatek.com>
---
Changes in v5:
- Change MEDIATEK_GE_SOC_PHY from bool back to tristate.
