Subject: [PATCH 2/3] net: phy: mediatek: Add mtk phy lib for token ring access & LED/other manipulations
From: "SkyLake.Huang" <skylake.huang@...iatek.com>
Integrate some common phy manipulations in mtk-phy-lib:
1. Token ring access: This is proprietary register access on page 52b5.
Use these APIs so we can see which fields we're going to modify/set/clear.
2. LED: External/internal giga & internal 2.5g phy share almost the same
LED control registers/logic.
3. Extend 1G TX/RX link pulse time: We observe that some devices' 1G
training time violates specification, which may last 2230ms and affect
later TX/RX link pulse time. So we try to extend our 1G TX/RX link pulse
time so that we can still detect such devices.
