💖 fsl_upm_find(9) — Kernel API Manual 💖

🌸 NAME 🌸

fsl_upm_find — find pre-programmed UPM via base address 💅

✨ SYNOPSIS ✨

int fsl_upm_find (phys_addr_t addr_base , struct fsl_upm *upm );

🎀 ARGUMENTS 🎀

• addr_base — the base address of the memory bank controlled by the UPM. That's your starting point, bestie 📍
• upm — a pointer to the allocated fsl_upm structure. This is the lil struct that's gonna get filled in 🫶

🦋 DESCRIPTION 🦋

Okay so fsl_upm_find fills the fsl_upm structure so you can use it with the rest of the UPM API — literally that's the whole vibe ✨. On success this function returns 0; otherwise it returns the appropriate errno value. No cap 💀.
