🌸 NAME 🌸

struct si2157_config — configuration parameters for si2157 ✨

✨ SYNOPSIS ✨

here's the struct in all its main-character glory, copied exactly so you can trust it fr fr:

struct si2157_config {
    struct dvb_frontend *fe;
  #if defined(CONFIG_MEDIA_CONTROLLER);
    struct media_device *mdev;
  #endif;
    unsigned int inversion:1;
    unsigned int dont_load_firmware:1;
    u8 if_port;
 };

👑 Members 👑

• fe — the frontend returned by the driver 🎀
• mdev — the media device returned by the driver 🦋
• inversion — spectral inversion, that's the vibe 🌈
• dont_load_firmware — instead of uploading a new firmware, use the existing one 🫶 no fresh upload required, bestie
• if_port — port selection: select the RF interface to use — pins 9+11 or 12+13 🎛️✨
