💅 omap2xxx_cm...module_ready(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ — this one's a little function from the OMAP2 clock-management corner of the kernel, and she is literally just sitting there waiting for a module to wake up. relatable tbh 😭

🌸 NAME 🌸

omap2xxx_cm_wait_module_ready — she waits for a module to leave idle or standby 🫶

✨ SYNOPSIS ✨

int omap2xxx_cm_wait_module_ready (u8 part , s16 prcm_mod , u16
       idlest_id , u8 idlest_shift );

like yes, four args, no cap 💅

🎀 ARGUMENTS 🎀

  • part — the PRCM partition, but bestie... she's ignored for OMAP2 🙈 like ok work
  • prcm_mod — the PRCM module offset, v important ✨
  • idlest_id — the CM_IDLESTx register ID (so, x = 1, 2, 3) 💖
  • idlest_shift — the shift of the bit in the CM_IDLEST* register you're checking 👑

🦋 DESCRIPTION 🦋

so the whole vibe here is: wait for the PRCM to indicate that the module identified by (prcm_mod, idlest_id, idlest_shift) is clocked ✨ that's it, that's the mission.

she returns 0 upon success 🌈 — or -EBUSY if the module doesn't enable in time 💀 (yes, she will absolutely give up on you, respectfully).

lowkey a mood: if the module doesn't show up on time, it's -EBUSY and we move on periodt.
