phy_start — start or restart a PHY device ✨

🎀 SYNOPSIS 🎀

void phy_start (struct phy_device *phydev );

🦋 ARGUMENTS 🦋

  • phydev — the target phy_device struct. that's your PHY bestie right there 🫶

✨ DESCRIPTION ✨

So this function is basically the “we’re ready, bestie” signal: it indicates the attached device’s readiness to handle PHY-related work.

You use it during startup to start the PHY, and also after a call to phy_stop to resume operation. lowkey essential 💅

It’s also used to indicate that the MDIO bus has cleared an error condition. slay, error condition cleared, we love to see it 🌈
