💅 regmap_sccb_write(9)

okay so bestie, welcome to the Kernel API Manual ✨ — yes we're literally in the kernel docs together, this is our moment 🫶

🌸 NAME 🌸

regmap_sccb_write — write data to an SCCB slave device 💖

⭐ SYNOPSIS ⭐

int regmap_sccb_write (void *context , unsigned int reg , unsigned int val );

🎀 ARGUMENTS 🎀

• context — the device that will be interacted with 🦋 like, this is who we're talking to, bestie
• reg — the register to write to ✨ the exact spot we're poking
• val — the value to be written 💅 the actual tea we're dropping in there

🔥 DESCRIPTION 🔥

okay so here's the vibe: this executes the SCCB 3-phase write transmission cycle 👑 no cap, three whole phases, it's giving choreography.

And what does it give back? Returning negative errno else zero on success 🌈 — so if you get a negative number, that's the kernel saying "girl, no 💀", and a zero means we ate and left no crumbs ✨
