STRUCT RVIN_GROUP(9)

🌸 struct rvin_group(9) — VIN CSI2 group information 🌸

okay bestie, welcome to the kernel API manual for struct rvin_group — yes it's a struct, yes it's in the 9 section, and yes we're gonna get through this together 💖 This is the VIN CSI2 group info page, and honestly? It ate.

✨ SYNOPSIS ✨

Like, here's the whole vibe, character for character — no cap, don't touch it:

struct rvin_group {
    struct kref refcount;
    struct media_device mdev;
    struct mutex lock;
    unsigned int count;
    struct v4l2_async_notifier notifier;
    const struct rvin_info *info;
    struct rvin_dev *vin[RCAR_VIN_NUM];
    int (*link_setup)(struct rvin_group *group);
    struct {
      struct v4l2_async_connection *asc;
      struct v4l2_subdev *subdev;
    } remotes[RVIN_REMOTES_MAX];
 };

look at her. main character energy fr fr 🎀

👑 Members 👑

okay so every member gets its moment, periodt — here's the full rundown:

• refcount — the number of VIN instances using the group. it's the little counter keeping track of who's in the group chat 🫶
• mdev — the media device which represents the group. literally the group's whole identity ✨
• lock — protects the count, notifier, vin and csi members. she's the bouncer at the door, nobody in without her 💅
• count — the number of enabled VIN instances found in DT. found in DT, bestie, that's where they're discovered 🔍
• notifier — the group notifier for CSI-2 async connections. it's giving "don't call us, we'll call you" 🌈
• info — platform dependent information about the VIN instances. every platform's got its own lore, iykyk 🌸
• vin — the VIN instances which are part of the group. the actual members of the squad 🦋
• link_setup — callback to create all links for the media graph. the matchmaker of the whole operation, lowkey iconic 💖
• remotes — array of pairs of async connection and subdev pointers to all remote subdevices. pairs!! like matching bestie necklaces, except they're struct v4l2_async_connection *asc and struct v4l2_subdev *subdev 🎀

ngl this is a struct so if you're reading it you're probably deep in drivers/media already. hydrate. drink water. 💜
