STRUCT UARTLITE_DATA(9)

💅 NAME 💅

ok so <purple>struct uartlite_data</purple> — literally just the driver's own private data, bestie. Like its little diary 🎀 that only this driver gets to read. And yup, we're doing this in the Kernel API Manual 'cause that's the whole vibe iykyk ✨

✨ SYNOPSIS ✨

here's the whole thing, no cap, every line exactly as it is:

struct uartlite_data {
    const struct uartlite_reg_ops *reg_ops;
    struct clk *clk;
    unsigned int baud;
    tcflag_t cflags;
 };

like... she's compact, she's iconic, she's giving lowkey-minimalist 👑

🦋 Members 🦋

okay let's break down our girl's fields one by one, because each one ATE:

• reg_ops — the functions used to read and write registers 🫶 this is literally how she talks to her hardware. no reg_ops, no conversation.
• clk — her parent clock, if present 🙈 that "if present" is doing a lot of work so don't @ me — sometimes there's just no parent clock and that's fine, it's a whole thing.
• baud — the baud rate that was configured back when this device was synthesized ⭐ like a little time capsule of the moment she came into existence.
• cflags — the cflags for parity and data bits 🌸 the actual personality settings fr fr.

🌈 SEE ALSO 🌈

go touch some grass in the kernel source, bestie:

• the kernel file ./drivers/tty/serial/uartlite.c
• ulite_suspend(9) 😴
• ulite_resume(9) ☀️

and that's the tea 🍓 this one lives at ./drivers/tty/serial, from October 2026, and it's all about <purple>struct uartlite_data(9)</purple> — mwah, go read it, ily, bye 💖🧚‍♀️💜
