🦋 of_clk_get_by_name(9) 🦋

okay bestie, welcome to the Kernel API Manual entry for of_clk_get_by_name(9) 💅 this is the function you call when your device tree node is like "hey, i need my clock" and you're like "say less, let me go find it" ✨

🌸 NAME 🌸

of_clk_get_by_name — parse and lookup a clock referenced by a device node 🎀

✨ SYNOPSIS ✨

struct clk * of_clk_get_by_name (struct device_node *np , const char *name );

💖 ARGUMENTS 💖

  • np — pointer to clock consumer node 🌈 like, the device tree node that's consuming the clock, not the one providing it, iykyk
  • name — name of consumer's clock input, or NULL for the first clock reference 👑 so if you're too lazy to name it, pass NULL and you get the first one, no cap

🧚 DESCRIPTION 🧚

okay so here's the vibe: this function parses the clocks and clock-names properties, and uses them to look up the struct clk from the registered list of clock providers 🫶

that's the whole thing. it reads the properties off your node, matches them up against everybody who's registered as a clock provider, and hands you back the struct clk * you've been waiting for. main character energy, honestly ⭐
