STRUCT OWL_PINGROUP(9)

🌈 struct owl_pingroup(9) 🌈

okay so this page is straight out of the Kernel API Manual, and it’s giving “tiny but crucial pinctrl struct” energy 🦋. We’re talking about struct owl_pingroup — the Actions pingroup definition — and yes, every member is getting its moment 💅.

✨ NAME ✨

struct owl_pingroup — Actions pingroup definition 👑

🎀 SYNOPSIS 🎀

       struct owl_pingroup {
           const char *name;
           unsigned int *pads;
           unsigned int npads;
           unsigned int *funcs;
           unsigned int nfuncs;
           int mfpctl_reg;
           unsigned int mfpctl_shift;
           unsigned int mfpctl_width;
           int drv_reg;
           unsigned int drv_shift;
           unsigned int drv_width;
           int sr_reg;
           unsigned int sr_shift;
           unsigned int sr_width;
        };

🌸 Members 🌸

okay bestie, here’s the member-by-member tour, no skipping, no “I’ll read it later” 🙈:

• name — name of the pin group. It’s the group’s little ID badge 💖.
• pads — list of pins assigned to this pingroup. Think guest list, but for pads ✨.
• npads — size of pads array. So you know how many pins are on that list 🎀.
• funcs — list of pinmux functions for this pingroup. The function menu, basically 🍓.
• nfuncs — size of funcs array. The count for that function menu 🔢.
• mfpctl_reg — multiplexing control register offset. Where the mux control register sits 📍.
• mfpctl_shift — multiplexing control register bit mask. The mask situation inside that multiplexing control register 🎭.
• mfpctl_width — multiplexing control register width. How wide that multiplexing control register situation is 📏.
• drv_reg — drive control register offset. Drive control register location unlocked 🚗.
• drv_shift — drive control register bit mask. The bit mask for the drive control register 🎚️.
• drv_width — driver control register width. Width of the driver control register, exactly as stated 👑.
• sr_reg — slew rate control register offset. Slew rate control register, found at this offset 🌈.
• sr_shift — slew rate control register bit mask. Bit mask for the slew rate control register 🧚.
• sr_width — slew rate control register width. Width of the slew rate control register ⭐.
