🌸 _omap2xxx_3xxx_wait_target_ready(9) — Kernel API Manual, bestie edition 🌸

okay so we're in the Kernel API Manual today and the star of the show is _omap2xxx_3xxx_wait_target_ready, aka the function that literally just sits there and waits for a hardware module to get its life together and stop being idle. it's giving "i'll wait" energy and honestly? iconic. 🎀

✨ NAME ✨

_omap2xxx_3xxx_wait_target_ready — wait for a module to leave slave idle 💅

like literally the whole job. module is in slave idle, we wait for it to not be. no cap. 🦋

🧚 SYNOPSIS 🧚

int _omap2xxx_3xxx_wait_target_ready (struct omap_hwmod *oh );

💖 ARGUMENTS 💖

  • oh — a struct omap_hwmod *. that's the module we're waiting on. that's it. that's the whole argument list. main character energy fr fr 👑

🌈 DESCRIPTION 🌈

so basically: you hand it a module oh, and it waits for that module to leave slave idle. that's the vibe check. ⭐

it returns 0 in two very specific situations, and i need you to clock both of them:

  • the module doesn't have an IDLEST bit at all — so like, nothing to wait for, we're done, bye 🫶
  • or the module does successfully leave slave idle — slay, 0, we love to see it ✨

otherwise (read: it didn't go the way we wanted), it just passes along the return value of the appropriate *_cm*_wait_module_ready function. not me forwarding the error like "this is yours now" 😭 literally just handing you whatever that call said.

no fairy dust here, bestie — the return value is either a clean 0 or whatever *_cm*_wait_module_ready decided to give you. that's the whole contract. keep it in mind. 💀
