STRUCT SAMSUNG_PIN_BANK_DATA(9)

💅 struct samsung_pin_bank_data — NAME ✨

okay so bestie, welcome to the Kernel API Manual 🫶 — this page is all about struct samsung_pin_bank_data, and it literally represents a controller pin-bank (init data). that's the whole vibe. init data. not the live one, the blueprint one. iykyk 💜

📜 SYNOPSIS 🌸

struct samsung_pin_bank_data {
    const struct samsung_pin_bank_type *type;
    u32 pctl_offset;
    u8 pctl_res_idx;
    u8 nr_pins;
    u8 eint_func;
    enum eint_type  eint_type;
    u32 eint_mask;
    u32 eint_offset;
    u32 eint_num;
    u32 eint_con_offset;
    u32 eint_mask_offset;
    u32 eint_pend_offset;
    u32 eint_fltcon_offset;
    const char      *name;
 };

periodt. that's the entire struct, copied exactly, no notes 💅

🎀 Members 👑

okay so this is the part where each field gets its moment, main character energy only:

• type — the type of the bank (register offsets and bitfield widths). it's giving "how do i read the registers" energy ✨
• pctl_offset — the starting offset of the pin-bank registers. like, where the registers begin. starting point. slay 🦋
• pctl_res_idx — the index of the base address for pin-bank registers. index. base address. yeah 💖
• nr_pins — number of pins included in this bank. literally just how many pins live here 🔥
• eint_func — the function to set in the CON register to configure a pin as EINT. CON register, capital letters, respect it 💀
• eint_type — the type of the external interrupt supported by the bank. highkey important 😭
• eint_mask — bit mask of pins which support the EINT function. bit masks are so iconic honestly 🌈
• eint_offset — SoC-specific EINT register or interrupt offset of the bank. SoC-specific. remember that ⭐
• eint_num — total number of eint pins. total! not partial! 💅
• eint_con_offset — ExynosAuto SoC-specific EINT control register offset of the bank. ExynosAuto, specifically, no cap 🍓
• eint_mask_offset — ExynosAuto SoC-specific EINT mask register offset of the bank. again: ExynosAuto. specifically. 🧚
• eint_pend_offset — ExynosAuto SoC-specific EINT pend register offset of the bank. pend register. ExynosAuto. you got this 💜
• eint_fltcon_offset — GS101 SoC-specific EINT filter config register offset. and this one's GS101, not ExynosAuto — different SoC, don't mix them up bestie 🙈
• name — the name to be prefixed for each pin in this pin bank. prefix. every pin. all of them. 🎀

lowkey a warning even though the original didn't say it dramatically: eint_con_offset, eint_mask_offset and eint_pend_offset are ExynosAuto-specific, and eint_fltcon_offset is GS101-specific. keep the SoCs straight and you'll be fine 🫶

alright that's the page! this little gem lives in ./drivers/pinctrl/samsung, dated October 2026, and it's titled struct samsu...in_bank_data(9) if you're being all formal about it. mwah, go configure some pins bestie 💖🎀🦋
