clk_hw_register_clkdev(9)

✨ clk_hw_register_clkdev 💅

ok so bestie, welcome to the clk_hw_register_clkdev page from the Kernel API Manual — that's the manual name, iykyk, we're in kernel-land now 🐧✨ This one's a lil function that registers one clock lookup for a struct clk_hw. One. Single. Lookup. Main character energy only 🔥

---

🎀 NAME

clk_hw_register_clkdev — register one clock lookup for a struct clk_hw 🕐

---

🌸 SYNOPSIS

int clk_hw_register_clkdev (struct clk_hw *hw , const char *con_id ,
       const char *dev_id );

like, that's the whole signature, no cap ✨

---

🦋 ARGUMENTS

• hw — the struct clk_hw you're associating with all the clk_lookups 💖
• con_id — the connection ID string on the device 🎀
• dev_id — a format string describing the device name 🫶 (yes, a format string, she's fancy)

---

🌈 DESCRIPTION

okay so here's the tea ☕ — con_id or dev_id may be NULL as a wildcard, literally just like in the rest of clkdev. wildcard vibes 🃏✨

and because mass registration should be easy (and we love efficiency in this house), the function detects error clk_hws from a previous clk_hw_register_*() call and returns the error code for those 💀 Like, it'll hand you back the error instead of pretending everything's fine. This is so you can call this function immediately after clk_hw_register_*() — no need to check first, she's got you 🫶👑
