pwrdm_add_clkdm(9)

💖 NAME 💖

pwrdm_add_clkdm — add a clockdomain to a powerdomain

Okay bestie, this is the pwrdm_add_clkdm(9) page from the Kernel API Manual — and it's giving “small function, big powerdomain energy” ✨

✨ SYNOPSIS ✨

int pwrdm_add_clkdm (struct powerdomain *pwrdm , struct clockdomain
*clkdm );

🎀 ARGUMENTS 🎀

• pwrdm — the struct powerdomain * you're adding the clockdomain to 💖
• clkdm — the struct clockdomain * to associate with a powerdomain 🫶

🦋 DESCRIPTION 🦋

Associate the clockdomain clkdm with a powerdomain pwrdm. This enables the use of pwrdm_for_each_clkdm. That's the whole point, periodt 💅

Return vibes are very specific, no cap: returns -EINVAL if presented with invalid pointers; -ENOMEM if memory could not be allocated; or 0 upon success 😭✅
