🎀 NAME 🎀

of_ti_clk_autoidle_setup — sets up hardware autoidle for a clock. that's it, that's the whole vibe 🫶

🦋 SYNOPSIS 🦋

int of_ti_clk_autoidle_setup (struct device_node *node );

---

🌸 ARGUMENTS 🌸

• node — pointer to the clock device node 💅

⭐ DESCRIPTION ⭐

so here's the tea ☕ — this function checks whether a clock has hardware autoidle support or not. how does it check? it looks for the presence of the 'ti,autoidle-shift' property in the device tree node. iykyk 🔥

if that support is available, it sets up the hardware autoidle feature for the clock. and not only that — the clock is also added to the autoidle list for later processing, because we're organized like that 💅✨

returns 0 on success, and a negative error value on failure. no cap 😭

lowkey important: it returns 0 on success, negative error value on failure. don't forget bestie 💖
