omap3430_pr...ure_io_chain(9)

💅 NAME 💅

omap3430_pre_es3_1_reconfigure_io_chain — bestie, this one's literally just here to restart the wake-up daisy chain 🔁✨

(this is from the Kernel API Manual, iykyk 🫶)

---

✨ SYNOPSIS ✨

void omap3430_pre_es3_1_reconfigure_io_chain (void );

---

🎀 ARGUMENTS 🎀

• void — no arguments. that's it. that's the whole vibe. nothing goes in, she works with what she's got 💅

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — the ST_IO_CHAIN bit does not exist in 3430 before es3.1. like, it's simply not there, not invited to the party 🙈

so the only thing we can do for those earlier omaps is toggle the EN_IO bit. that's the whole move. no ST_IO_CHAIN, no problem — we just flip EN_IO and hope for the best, fr fr 🧚

lowkey iconic that the fallback is this simple, but also 😭 that there's no other option for pre-es3.1 silicon.
