STRUCT M88DS3103_CONFIG(9)

💖 NAME 💖

okay so bestie, welcome to the struct m88ds3103_config(9) page from the Kernel API Manual — it's literally the config struct for m88ds3102, and the NAME line says struct m88ds3103_config - m88ds3102 configuration. Yes, the numbers are different, and no, we are not changing them — that's the source, periodt. 💅

This struct is a whole little wardrobe of settings, and every member has a default or a must-set warning. Let's unpack it like a group chat. ✨

🌸 SYNOPSIS 🌸

Here's the exact struct, bestie — every field, every bitfield, every semicolon:

struct m88ds3103_config {
    u8 i2c_addr;
    u32 clock;
    u16 i2c_wr_max;
    u8 ts_mode;
    u32 ts_clk;
    u8 ts_clk_pol:1;
    u8 spec_inv:1;
    u8 agc_inv:1;
    u8 clock_out;
    u8 envelope_mode:1;
    u8 agc;
    u8 lnb_hv_pol:1;
    u8 lnb_en_pol:1;
};

🎀 Members 🎀

Every member is doing its own main-character thing:

• i2c_addr — the I2C address, bestie. Default: none, must set. Example: 0x68, ...
• clock — the device's clock. Default: none, must set. Example: 27000000.
• i2c_wr_max — max bytes the I2C provider is asked to write at once. Default: none, must set. Example: 33, 65, ...
• ts_mode — TS output mode, as defined by enum m88ds3103_ts_mode. Default: M88DS3103_TS_SERIAL.
• ts_clk — TS clk in KHz. Default: 0.
• ts_clk_pol — TS clk polarity. Default: 0. 1-active at falling edge; 0-active at rising edge.
• spec_inv — spectrum inversion. Default: 0.
• agc_inv — AGC polarity. Default: 0.
• clock_out — clock output, as defined by enum m88ds3103_clock_out. Default: M88DS3103_CLOCK_OUT_DISABLED.
• envelope_mode — DiSEqC envelope mode. Default: 0.
• agc — AGC configuration. Default: none, must set.
• lnb_hv_pol — LNB H/V pin polarity. Default: 0. Values: 1: pin high set to VOLTAGE_13, pin low to set VOLTAGE_18; 0: pin high set to VOLTAGE_18, pin low to set VOLTAGE_13.
• lnb_en_pol — LNB enable pin polarity. Default: 0. Values: 1: pin high to enable, pin low to disable; 0: pin high to disable, pin low to enable.

The "none, must set" energy is real for i2c_addr, clock, i2c_wr_max, and agc — no cap, go fill them in. 🫶
