STRUCT HTC_EGPIO_PLATFORM_DATA(9)

🌸 htc_egpio_platform_data — struct htc_egpio_platform_data(9) 🌸

okay bestie, welcome to the Kernel API Manual ✨ this one's a little struct that's just, like, totally described by the arch. no cap — the NAME literally says "description provided by the arch," which is giving "the arch knows, not me" 💅

✨ NAME ✨

struct htc_egpio_platform_data — description provided by the arch 🫶

🦋 SYNOPSIS 🦋

       struct htc_egpio_platform_data {
           int bus_width;
           int reg_width;
           int irq_base;
           int num_irqs;
           int invert_acks;
           int ack_register;
           struct htc_egpio_chip *chip;
           int num_chips;
        };

🎀 Members 🎀

okay so this is the part where we meet every single field, and yes there are eight of them, we're not skipping a single one 😤

• bus_width — the alignment of the registers, either 16 or 32 bit. pick one, bestie, those are the options.
• reg_width — the number of bits per register, either 8 or 16 bit. again: two choices, that's it.
• irq_base — the beginning of the available IRQs (eg, IRQ_BOARD_START) ⭐ like where the IRQ party starts.
• num_irqs — the number of irqs 🔥
• invert_acks — set this if the chip requires writing '0' to ack an irq, instead of '1'. so it's the "flip the ack" switch, basically the icon of doing things backwards 🙈
• ack_register — the location of the irq/ack register 📍
• chip — pointer to an array of htc_egpio_chip descriptors. like, a whole squad of descriptors 👑
• num_chips — the number of egpio chip descriptors. count your chips, bestie 🍓

fr fr, that's the whole struct. no hidden fields, no plot twists. just vibes and register widths ✨

and that's a wrap, bestie!! this page came from source ./include/linux/platform_data and it's dated October 2026 🗓️ slay, go build some kernels 💅🫶
