STRUCT TEGRA_CSI_CHANNEL(9)

🦋 struct tegra_csi_channel — the Tegra CSI channel ✨

okay so this is struct tegra_csi_channel(9), straight out of the Kernel API Manual, and bestie it is literally the whole personality of one Tegra CSI channel. one channel. one struct. main character energy fr fr 💅

🌸 NAME 🌸

struct tegra_csi_channel — Tegra CSI channel. that's it, that's the vibe check 🎀

⭐ SYNOPSIS ⭐

struct tegra_csi_channel {
    struct list_head list;
    struct v4l2_subdev subdev;
    struct media_pad pads[TEGRA_CSI_PADS_NUM];
    unsigned int numpads;
    struct tegra_csi *csi;
    struct device_node *of_node;
    u8 numgangports;
    unsigned int numlanes;
    u8 csi_port_nums[GANG_PORTS_MAX];
    u8 pg_mode;
    struct v4l2_mbus_framefmt format;
    unsigned int framerate;
    unsigned int h_blank;
    unsigned int v_blank;
    struct tegra_mipi_device *mipi;
    unsigned int pixel_rate;
 };

no cap, copy it exactly, don't you dare "fix" the indentation on that last brace 😭

💖 Members 💖

• list — the list head for this entry, keeping the whole squad linked up 🫶
• subdev — the V4L2 subdevice that's associated with this channel. iconic.
• pads — the media pads for the subdevice entity ✨
• numpads — number of pads. yes with the period, we respect the period 🎀
• csi — the Tegra CSI device structure, aka the parent energy 👑
• of_node — the csi device tree node 🌈
• numgangports — the number of immediate ports ganged up to meet the channel bus-width. gang gang 💀
• numlanes — number of lanes used per port 🦋
• csi_port_nums — the CSI channel port numbers, all arrayed and ready 📋
• pg_mode — test pattern generator mode for the channel. tpg bestie 🌸
• format — the active format of the channel 💅
• framerate — active framerate for TPG 🔥
• h_blank — horizontal blanking for the TPG active format 🍓
• v_blank — vertical blanking for the TPG active format 🍓
• mipi — mipi device for the corresponding csi channel pads, or NULL if not applicable (TPG, error). so like... sometimes it's just not that girl 🙈
• pixel_rate — the active pixel rate from the sensor on this channel ⭐
