omap4_cminst_wait_module_idle(9) 🫶

okay bestie, you're in the Kernel API Manual and this page is about omap4_cminst_wait_module_idle — the little function whose whole personality is waiting for a module to be in the 'disabled' state. no cap, it's giving "hold my iced coffee while the hardware settles." 💅

💖 NAME

omap4_cminst_wait_module_idle — wait for a module to be in 'disabled' state. periodt.

✨ SYNOPSIS ✨

int omap4_cminst_wait_module_idle (u8 part , s16 inst , u16 clkctrl_offs
, u8 bit_shift );

🎀 ARGUMENTS 🎀

• part — PRCM partition ID that the CM_CLKCTRL register exists in.
• inst — CM instance register offset (*_INST macro).
• clkctrl_offs — Module clock control register offset (*_CLKCTRL macro).
• bit_shift — Bit shift for the register, ignored for OMAP4+.

🦋 DESCRIPTION 🦋

okay so the whole assignment is: wait for the module IDLEST to be disabled. that's it, that's the function. Some PRCM transition, like reset assertion or parent clock de-activation, must wait for the module to be fully disabled — so this one is literally the "are we there yet" bestie for that exact moment. 💖
