AW_GPIO(4)

💅 AW_GPIO(4) — the Allwinner GPIO glow-up, bestie ✨

okay so this is the <pink>AW_GPIO</pink> manual page from the <lavender>arm Kernel Interfaces Manual</lavender>, and it's literally all about the driver for the GPIO and pin muxing functionalities on Allwinner SoC. buckle up, it's a short one but we're gonna make it iconic 🎀

✨ NAME ✨

aw_gpio — driver for the GPIO and pin muxing functionalities on Allwinner SoC

the way this driver just handles pin muxing AND GPIO? main character energy fr fr 😭💖

like, pick your SoC and slay, it's giving choose-your-own-adventure but make it kernel config 🌸

💫 DESCRIPTION 💫

the aw_gpio device driver literally provides support for the Allwinner pin muxing and GPIO on Allwinner SoCs. that's it. that's the vibe. no cap, it just does its job and serves looks while doing it 👑

🔥 HARDWARE 🔥

the current version of the aw_gpio driver supports the GPIO/pinmuxing controller with one of the following compatible strings — so like, if your device tree says one of these, you're in, bestie:

• allwinner,sun4i-a10-pinctrl
• allwinner,sun5i-a13-pinctrl
• allwinner,sun7i-a20-pinctrl
• allwinner,sun6i-a31-pinctrl
• allwinner,sun6i-a31s-pinctrl
• allwinner,sun6i-a31-r-pinctrl
• allwinner,sun6i-a33-pinctrl
• allwinner,sun8i-a83t-pinctrl
• allwinner,sun8i-a83t-r-pinctrl
• allwinner,sun8i-h3-pinctrl
• allwinner,sun50i-h5-pinctrl
• allwinner,sun8i-h3-r-pinctrl
• allwinner,sun50i-a64-pinctrl
• allwinner,sun50i-a64-r-pinctrl

the way that list just goes — fourteen compatible strings, all iconic, no skips 💅✨

go read those too, iykyk, they're the supporting cast and they ate 💖

🌈 HISTORY 🌈

the aw_gpio device driver first appeared in FreeBSD 10.0. vintage. classic. a real throwback moment 🕰️🌸

👑 AUTHORS 👑

the aw_gpio device driver was originally written by Ganbold Tsagaankhuu <ganbold@freebsd.org>. this manual page was written by Emmanuel Vadot <manu@freebsd.org>. shoutout to the OGs, they understood the assignment fr fr 🙌

okay that's the whole page bestie — no notes, we covered every option, every compatible string, every author, and every vibe. this was the AW_GPIO(4) manual page from Debian, dated Dec 25, 2017, and honestly? she's a little short but she's perfect 💜🦋✨
