STRUCT BCM2835AUX_DATA(9)

✨ NAME ✨

struct bcm2835aux_data — the driver's very own private stash of data for the BCM2835 auxiliary UART, no cap 💅

🌸 SYNOPSIS 🌸

struct bcm2835aux_data {
    struct clk *clk;
    int line;
    u32 cntl;
 };

okay so it's a struct, it's got three fields, and it's literally the whole personality of this driver 🎀

🦋 Members 🦋

• clk — a struct clk *, aka the clock producer for the port's uartclk. it's giving "source of truth for the baud rate vibes" ⏰✨
• line — an int, the index of this port's entry in serial8250_ports[]. like a little seat number in the big array auditorium 🎟️
• cntl — a u32, a cached copy of the CNTL register. we keep it close so we don't have to go re-reading it, iconic behavior honestly 💾👑

🔥 SEE ALSO 🔥

• Kernel file ./drivers/tty/serial/8250/8250_bcm2835aux.c — go read it bestie, that's where all of this actually lives 🫶

ngl this whole page was short and sweet and I'm obsessed 🍓

mwah 💋 that's a wrap from ./drivers/tty/serial/8250, dated October 2026 — stan the kernel docs, periodt 💜🧚
