_omap4_wait_target_ready(9)

💖 NAME 💖

Okay bestie, this is the _omap4_wait_target_ready(9) page from the Kernel API Manual, and it is literally about one tiny job: wait for a module to leave slave idle. Slay. 💅

✨ SYNOPSIS ✨

int _omap4_wait_target_ready (struct omap_hwmod *oh );

🎀 ARGUMENTS 🎀

• oh — struct omap_hwmod *; that’s the module we’re checking on. That’s the whole arg, no cap. 🫶

🦋 DESCRIPTION 🦋

Okay so the vibe check: wait for module oh to leave slave idle. Periodt. ✨

Here’s the return-value tea, and it matters: it returns 0 if the module does not have an IDLEST bit, or if the module successfully leaves slave idle. Otherwise, it passes along the return value of the appropriate *_cm*_wait_module_ready function. No extra lore, that’s it. 💖
