STRUCT ZD1301_DEMOD_PLATFORM_DATA(9)

✨ struct zd1301_demod_platform_data ✨

okay bestie, so this is a page from the Kernel API Manual (yes, that manual, the ✨iconic✨ one) and we're about to get into some platform data for the zd1301_demod driver. it's giving "small struct, big responsibilities" and honestly? i'm obsessed. let's go 💅

---

🌸 NAME 🌸

struct zd1301_demod_platform_data — the platform data for the zd1301_demod driver, fr fr 🫶

---

🎀 SYNOPSIS 🎀

here's the whole vibe, character for character, do not touch:

struct zd1301_demod_platform_data {
    void *reg_priv;
    int (*reg_read)(void *, u16, u8 *);
    int (*reg_write)(void *, u16, u8);
 };

like, that's it. that's the whole struct. three little members carrying the entire register-access situation on their backs. main character energy, no cap 👑

---

💖 Members 💖

• reg_priv — this is the first argument that gets handed to your reg_read and reg_write callbacks. think of it as the lil' backpack of context that travels with every call. 🎒
• reg_read — the register read callback. you supply it, the driver calls it, register gets read. slay. 🔥
• reg_write — the register write callback. same deal but it writes. iconic behavior. ✨

ngl bestie, these three are a package deal — the two callbacks both take that reg_priv pointer as their first arg, so keep that in mind when you're wiring them up 🙈

🦋 SEE ALSO 🦋

• the kernel file itself, literally right here: ./drivers/media/dvb-frontends/zd1301_demod.h 🍓
• zd1301_demod_get_dvb_frontend(9) — another page, another adventure
• zd1301_demod_get_i2c_adapter(9) — same energy, different getter

aaaand that's the whole thing! 🌈 this little beauty lives over in the kernel source at ./drivers/media/dvb-frontends, and this version of the page is dated October 2026. go forth and register-read/write responsibly, bestie 💜🧚👑
