cci_write(9)

🌸 NAME 🌸

okay bestie, meet cci_write(9) from the Kernel API Manual — it writes a value to a single CCI register. slay, that's literally the whole vibe. 💅

✨ SYNOPSIS ✨

int cci_write (struct regmap *map , u32 reg , u64 val , int *err );

🎀 ARGUMENTS 🎀

• map — the register map you're writing to, bestie. main character energy. 🗺️
• reg — the register address to write. use the CCI_REG#() macros to encode the reg width, okay? iykyk ✨
• val — the value being written. that's it, that's the value. 💖
• err — optional pointer to store errors. if a previous error is already set, then the write will be skipped. no cap, it just skips. 🫶

🦋 RETURN 🦋

0 on success, or a negative error code on failure. periodt. 💀✨
