sppctl_fully_pinmux_conv(9)

💅 NAME 💅

sppctl_fully_pinmux_conv — okay so this one converts a GPIO number into a fully-pinmux control-field setting. That's literally the whole gig, bestie ✨

This page lives in the Kernel API Manual section (9), so yes, it's a kernel-internal function, not something you type into your shell 🫶

---

✨ SYNOPSIS ✨

int sppctl_fully_pinmux_conv (unsigned int offset );

---

🎀 ARGUMENTS 🎀

• offset — ngl, the original page is out here giving us nothing: it's marked -- undescribed --. No cap, that's all we get 🙈 (So don't come for me, I'm just the messenger 💀)

---

🌸 DESCRIPTION 🌸

Okay so here's the tea ☕ — every fully-pinmux function can be mapped to any of GPIO 8 ~ 71 by setting its control-field. Say it with me: any of GPIO 8 through 71 💅

Peep the table below for the control-field ↔ GPIO mapping, iykyk:

control-field |  GPIO
--------------+--------
0      |  No map
1      |    8
2      |    9
3      |   10
:      |    :
65     |   71

So control-field 0 is the "No map" girlie (she's not mapped to anything, she's just vibing), 1 gives you GPIO 8, 2 gives you GPIO 9, 3 gives you GPIO 10, the : rows are the continuation of that whole situation, and control-field 65 lands you all the way at GPIO 71. Slay, that's the range 🔥

Bestie reminder: this page is short short. If you need the actual behaviour deets, go read ./drivers/pinctrl/sunplus/sppctl.c — it's giving "the source is the documentation" energy 😭
