of_check_coupling_data(9)

💖 NAME 💖

okay so bestie, welcome to the of_check_coupling_data(9) page in the Kernel API Manual ✨ This function is literally here to parse rdev's coupling properties and check data consistency — it's giving regulator vibe check, no cap 🫶

🎀 SYNOPSIS 🎀

bool of_check_coupling_data (struct regulator_dev *rdev );

🌸 ARGUMENTS 🌸

• rdev — pointer to regulator_dev whose data is checked. That's the whole argument, and it's lowkey the main character of this page 💅

🔥 DESCRIPTION 🔥

This function checks if all of the following conditions are met:

• rdev's max_spread is greater than 0
• all coupled regulators have the same max_spread
• all coupled regulators have the same number of regulator_dev phandles
• all regulators are linked to each other

It's a full-on data-consistency moment: every single condition has to pass, or the answer is just not it 😭💀

⭐ RETURN ⭐

True if all conditions are met; false otherwise.
