okay bestie, welcome to the Kernel API Manual page for of_pm_clk_add_clks(9) — manual name folded in right at the top, we're being efficient and cute ✨

🌸 NAME 🌸

of_pm_clk_add_clks — start using device clock(s) for power management. periodt.

✨ SYNOPSIS ✨

int of_pm_clk_add_clks (struct device *dev );

🎀 ARGUMENTS 🎀

• dev — the device whose clock(s) is going to be used for power management. like, this is the device we're doing the clock power-management thing for 💅

🦋 DESCRIPTION 🦋

So here's the vibe: you add a series of clocks described in the 'clocks' device-tree node for a device to the list of clocks used for the power management of dev.

On success, it returns the number of clocks added. Returns a negative error code if there are no clocks in the device node for the device or if adding a clock fails. that's the whole check 😭✨
