of_clk_set_defaults(9)

okay bestie, welcome to the of_clk_set_defaults(9) page from the Kernel API Manual — yes, manual name folded in near the top, we're so efficient 💅

🎀 NAME 🎀

of_clk_set_defaults — parse and set assigned clocks configuration. That's the vibe: read the assigned-clock situation and apply it, periodt ✨

✨ SYNOPSIS ✨

int of_clk_set_defaults (struct device_node *node , bool clk_supplier );

🌸 ARGUMENTS 🌸

• node — the device node to apply clock settings for 🫶
• clk_supplier — true if clocks supplied by node should also be considered 👑

🦋 DESCRIPTION 🦋

Okay so this function parses the 'assigned-{clocks/clock-parents/clock-rates}' properties and sets any specified clock parents and rates. It's giving assigned-clock matchmaker, and honestly? Obsessed 💖

The clk_supplier argument should be set to true if node may be also a clock supplier of any clock listed in its 'assigned-clocks' or 'assigned-clock-parents' properties. If clk_supplier is false, the function exits returning 0 as soon as it determines the node is also a supplier of any of the clocks. Not me watching it dip early 😭 but that's literally the documented behavior.
