s5p_ahash_dma_init(9)

💖 s5p_ahash_dma_init(9) 💖

hey bestie!! welcome to the Kernel API Manual corner where we talk about s5p_ahash_dma_init — the function that's literally about to enable DMA and set the HASH flow inside SecSS. no cap, she's a whole vibe 💅✨

---

🎀 NAME 🎀

• s5p_ahash_dma_init — enable DMA and set HASH flow inside SecSS 💖

---

🦋 SYNOPSIS 🦋

void s5p_ahash_dma_init (struct s5p_aes_dev *dev , u32 hashflow );

---

🌸 ARGUMENTS 🌸

• dev — the secss device, aka the main character you're handing over 🫶
• hashflow — the HASH stream flow with/without AES/DES, so yes bestie, it can be with or without them 💖

---

✨ DESCRIPTION ✨

okay so real talk, here's the whole glow-up this function does: it flushes the HASH DMA and enables DMA, sets the HASH stream flow inside SecSS HW, and enables the HASH irq's HRDMA, HDONE, and HPART. that's the entire assignment, and she ate 🔥💅
