okay so bestie, welcome to the Kernel API Manual entry for ax_spi_read, and honestly? it's giving "small function, big main character energy" ✨ like don't let the tiny synopsis fool you, this lil guy is out here doing register reads, 32 bits per word, and we are OBSESSED 💖

🌸 NAME 🌸

ax_spi_read — Register Read - 32 bit per word 🎀

like literally, it reads a register. 32 bits. per word. no cap, that's the whole vibe 🔥

🦋 SYNOPSIS 🦋

u32 ax_spi_read (struct ax_spi *xspi , u32 offset );

that's it. that's the whole call. short king behavior fr fr 👑

✨ ARGUMENTS ✨

  • xspi — Pointer to the ax_spi structure 🫶 like, hand over your ax_spi pointer and she'll know what to do with it

Returns the value of that register 💫 that's it, that's the tea — you ask for a register, you get the register's value back, slay

🌈 SEE ALSO 🌈

okay so this is the whole group chat 💬 — everybody lives in the kernel file ./drivers/spi/spi-axiado.c and honestly the friend group is huge, so let's do a roll call:

like... twenty-two entries. twenty-two!! the way this driver has more friends than me 😭 but periodt, we love a well-connected SPI driver 💅

ngl bestie, if you're poking at registers, go read the friends above too — they're all in the same file and they all know each other 🧚

and that's the page!! ily, go read some registers responsibly 🍓

— cute lil sign-off: this gem lives over in ./drivers/spi 📁 and it's dated October 2026 ⭐ and yes it's still ax_spi_read(9), the icon, the legend, the 32-bit-per-word queen 👑💖
