ssp_flush(9)

✨ NAME ✨

okay so bestie, this is ssp_flush(9) — straight outta the Kernel API Manual — and it flushes the transmit and receive FIFOs. periodt. 💅

🌸 SYNOPSIS 🌸

int ssp_flush (void );

🎀 ARGUMENTS 🎀

• void — literally no arguments, bestie. not a single one. 🫶

🦋 DESCRIPTION 🦋

So like, ssp_flush waits for the SSP to idle, and it makes sure that the receive FIFO is empty. that's the vibe. ✨

Heads up bestie: the caller is expected to perform the necessary locking. so do your lock thing before you call it, okay? 🔒

💖 RETURN 💖

• -ETIMEDOUT — a timeout occurred 😭
• 0 — success, slay! 🎉
