STRUCT ACPI_DEVICE_SOFTWARE_NODE_PORT(9)

✨ struct acpi_device_software_node_port — NAME ✨

okay bestie, gather round 💖 this is the manual page for struct acpi_device_software_node_port, which is literally the MIPI DisCo for Imaging CSI-2 port. Yes that's a mouthful, yes it's iconic, no we're not renaming it. This page lives in the Kernel API Manual, section 9 👑

🌸 SYNOPSIS 🌸

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

struct acpi_device_software_node_port {
    char port_name[ACPI_DEVICE_SWNODE_PORT_NAME_LENGTH + 1];
    u32 data_lanes[ACPI_DEVICE_CSI2_DATA_LANES];
    u32 lane_polarities[ACPI_DEVICE_CSI2_DATA_LANES + 1 ];
    u64 link_frequencies[ACPI_DEVICE_CSI2_DATA_LANES];
    unsigned int port_nr;
    bool crs_csi2_local;
    struct property_entry
port_props[ACPI_DEVICE_SWNODE_PORT_NUM_ENTRIES];
    struct property_entry ep_props[ACPI_DEVICE_SWNODE_EP_NUM_ENTRIES];
    struct software_node_ref_args remote_ep[1];
 };

like… she's structured, she's got arrays, she's got a bool. main character energy fr fr 🎀

🦋 Members 🦋

okay so every single field, no skipping, let's go 🫶

• port_name — the port name. that's it, that's the whole thing 💅
• data_lanes — the "data-lanes" property values. yes plural, yes it's an array.
• lane_polarities — the "lane-polarities" property values. also plural.
• link_frequencies — the "link_frequencies" property values. (u64s, fancy ✨)
• port_nr — the port number.
• crs_csi2_local — _CRS CSI2 record present (i.e. this is a transmitter one). 👀 like, if this is true, she's transmitting, periodt.
• port_props — the port properties.
• ep_props — the endpoint properties.
• remote_ep — a reference to the remote endpoint. reaching out across the link, lowkey romantic 😭🫶
