dwc2_hsotg_wait_bit_clear(9)

💅 dwc2_hsotg_wait_bit_clear(9) 💅

okay so bestie, this one is from the Kernel API Manual, and it’s literally all about waiting for a bit to be clear. no cap, that’s the whole vibe. 🫶

---

✨ NAME ✨

dwc2_hsotg_wait_bit_clear — waits for bit to be clear. 💅

---

🦋 SYNOPSIS 🦋

int dwc2_hsotg_wait_bit_clear (struct dwc2_hsotg *hsotg , u32 offset ,
u32 mask , u32 timeout );

---

🎀 ARGUMENTS 🎀

• hsotg — programming view of the DWC_otg controller. that’s the controller’s whole POV, bestie. 👑
• offset — the register’s offset where the bit/bits must be set. yes, set — we’re keeping the original wording, don’t come for me 😭
• mask — mask of the bit/bits which must be set. slay, it’s giving “which bits are we checking” energy. ✨
• timeout — timeout to wait. the “how long are we gonna sit here” number. ⏳

---

🔥 RETURN 🔥

0 if bit/bits are set, or -ETIMEDOUT in case of timeout. periodt. 💀
