STRUCT SDW_SLAVE_OPS(9)

💅 struct sdw_slave_ops(9) 💅

✨ NAME ✨

struct sdw_slave_ops — Slave driver callback ops, bestie. this page is part of the Kernel API Manual and it's literally the callback-ops struct for a Slave driver. 🫶

🌸 SYNOPSIS 🌸

okay so here's the exact shape, no cap — every field stays exactly as-is:

struct sdw_slave_ops {
    int (*read_prop)(struct sdw_slave *sdw);
    int (*interrupt_callback)(struct sdw_slave *slave, struct sdw_slave_intr_status *status);
    int (*update_status)(struct sdw_slave *slave, enum sdw_slave_status status);
    int (*bus_config)(struct sdw_slave *slave, struct sdw_bus_params *params);
    int (*port_prep)(struct sdw_slave *slave, struct sdw_prepare_ch *prepare_ch, enum sdw_port_prep_ops pre_ops);
    int (*clk_stop)(struct sdw_slave *slave, enum sdw_clk_stop_mode mode, enum sdw_clk_stop_type type);
};

🦋 Members 🦋

the member lineup, with zero details dropped:

• read_prop — reads the Slave properties. slay. 🍓
• interrupt_callback — Device interrupt notification, and yes — it's invoked in thread context. important! 📌
• update_status — updates the Slave status. ✨
• bus_config — updates the bus config for Slave. 🚌
• port_prep — prepares the port with parameters. 🎀
• clk_stop — handles imp-def sequences before and after prepare and de-prepare. iconic, mysterious, iykyk. 🌀
