spmi_register_write(9)

📦 version 7.3.1, in nixpkgs unstable

💅 spmi_register_write — register write

ok so bestie, this is spmi_register_write from the Kernel API Manual (section 9, kernel-space lore ✨). It's a tiny little function that does exactly one iconic thing, and honestly? It ate. Let's get into it 🫶

✨ SYNOPSIS ✨

int spmi_register_write (struct spmi_device *sdev , u8 addr , u8 data );

that's it. that's the whole vibe. three args, one int back, no cap 💅

🎀 ARGUMENTS 🎀

  • sdev — the SPMI device, aka the main character of this whole operation 🦋
  • addr — the slave register address, and listen, it's a 5-bit address so don't go trying to be cute with it, it's a 5-bit address, periodt.
  • data — the buffer holding the data that's gonna be transferred over to the Slave 🌸

💖 DESCRIPTION 💖

It writes 1 byte of data to a Slave device register.

one byte. that's the whole plot. not two, not a "little bit more", one singular byte, and it's giving minimalist queen energy 👑 ngl it's lowkey refreshing how unbothered this function is.
