__phy_clear_bits(9)

💅 __phy_clear_bits(9) 💅

okay bestie, welcome to the Kernel API Manual — this is the page for __phy_clear_bits(9), and it is literally the convenience function for clearing bits in a PHY register. let's go 🫶

💖 NAME 💖

__phy_clear_bits — convenience function for clearing bits in a PHY register.

🌸 SYNOPSIS 🌸

int __phy_clear_bits (struct phy_device *phydev , u32 regnum , u16 val );

🎀 ARGUMENTS 🎀

• phydev — the phy_device struct. the main character struct, periodt.
• regnum — register number to write.
• val — bits to clear.

🦋 DESCRIPTION 🦋

The caller must have taken the MDIO bus lock. 🔒

Like, for real for real: the caller must have taken the MDIO bus lock. that is the whole vibe check here, bestie — no cap.
