💅 cail_pll_read — read PLL register

okay so this page lives in the Kernel API Manual (section 9, kernel API gang ✨) and it's literally just about reading one (1) PLL register. tiny page, big "i know what i'm doing" energy.

✨ NAME ✨

cail_pll_read — read PLL register

yes bestie, that's the whole thing: it reads the PLL register. she's an accessor and she knows it 🎀

🦋 SYNOPSIS 🦋

uint32_t cail_pll_read (struct card_info *info , uint32_t reg );

that's the whole signature, no cap. returns a uint32_t, takes your struct card_info * and your uint32_t register offset. two args, zero drama 💅

🌸 ARGUMENTS 🌸

  • info — atom card_info pointer. it's your card info, the atom flavor of it 🫶
  • reg — PLL register offset. the actual address-y number you wanna peek at 👑

💖 DESCRIPTION 💖

okay so here's the vibe: this is a PLL register accessor, and it exists for the atom interpreter (r4xx+). that's the whole job description.

call it and it returns the value of the PLL register. that's it. that's the function. she's a getter, she's reliable, she ate and left no crumbs ⭐

no, seriously — the whole description is "provides a PLL register accessor for the atom interpreter (r4xx+)" and "returns the value of the PLL register." that's the entire lore. i'm not gonna invent more for you 🧚
