_add_hwmod_clocks_clkdev(9)

💅 _add_hwmod_clocks_clkdev(9) — the kernel API manual, but make it make sense

okay bestie, welcome to the _add_hwmod_clocks_clkdev page from the Kernel API Manual ✨ this one's a kernel-internals girlie, so grab a lil snack and let's get into it 🍓

---

🌸 NAME 🌸

_add_hwmod_clocks_clkdev — adds a clkdev entry for the hwmod optional clocks and the main clock, no cap 💅

---

✨ SYNOPSIS ✨

void _add_hwmod_clocks_clkdev (struct omap_device *od , struct omap_hwmod *oh );

like, that's the whole vibe. void, two pointers, we move 🦋

---

🎀 ARGUMENTS 🎀

• od — a struct omap_device *od. yeah that's literally it, that's the whole description, the manpage said so and I'm not gonna invent lore 🙈
• oh — a struct omap_hwmod *oh. same energy. pointer. hwmod. iconic 👑

---

🧚 DESCRIPTION 🧚

so here's what she does 💖 for the main clock and for every optional clock present per hwmod per omap_device, this function adds an entry into the clkdev table shaped like this:

<dev-id=dev_name, con-id=role>

…but only if it does not exist already. no duplicates, we're not messy like that 🫶

and why do we care? because this is what lets drivers get a pointer to their optional clocks based on their role, by calling:

clk_get(<dev*>, <role>)

for the main clock, a "fck" alias is used — that's the little nickname, iykyk ⭐

and the return value? none. no return value, she returns nothing, void is the whole personality. periodt 💀
