💅 si476x_core_cmd_zif_pin_cfg(9) — the Kernel API Manual glow-up

okay bestie, so this is a page straight out of the Kernel API Manual, and it's all about one very specific little function called si476x_core_cmd_zif_pin_cfg. it's niche, it's crunchy, it's lowkey iconic. let's get into it 🫶

✨ NAME ✨

si476x_core_cmd_zif_pin_cfg — literally just sends the 'ZIF_PIN_CFG_COMMAND'. that's the whole job. she's a messenger. 💌

🌸 SYNOPSIS 🌸

int si476x_core_cmd_zif_pin_cfg (struct si476x_core *core , enum
si476x_iqclk_config iqclk , enum si476x_iqfs_config iqfs , enum
si476x_iout_config iout , enum si476x_qout_config qout );

four enum args and a core, no cap. the way that signature just sits there. ✨

🎀 ARGUMENTS 🎀

  • core — the device you're sending the command to. your main character, fr fr.
  • iqclk — the IQCL pin function configuration, and the options are:
    • SI476X_IQCLK_NOOP — do not modify the behaviour. she's unbothered. 🙈
    • SI476X_IQCLK_TRISTATE — put the pin in tristate condition, enable 1MOhm pulldown.
    • SI476X_IQCLK_IQ — set pin to be a part of I/Q interface in master mode. main character energy 👑
  • iqfs — the IQFS pin function configuration:
    • SI476X_IQFS_NOOP — do not modify the behaviour.
    • SI476X_IQFS_TRISTATE — put the pin in tristate condition, enable 1MOhm pulldown.
    • SI476X_IQFS_IQ — set pin to be a part of I/Q interface in master mode.
  • iout — the IOUT pin function configuration:
    • SI476X_IOUT_NOOP — do not modify the behaviour.
    • SI476X_IOUT_TRISTATE — put the pin in tristate condition, enable 1MOhm pulldown.
    • SI476X_IOUT_OUTPUT — set pin to be I out. yes bestie, I is for I. 💅
  • qout — the QOUT pin function configuration:
    • SI476X_QOUT_NOOP — do not modify the behaviour.
    • SI476X_QOUT_TRISTATE — put the pin in tristate condition, enable 1MOhm pulldown.
    • SI476X_QOUT_OUTPUT — set pin to be Q out. matching set, we love symmetry 🎀

🦋 DESCRIPTION 🦋

the function returns 0 on success and a negative error code on failure. that's it, that's the lore. not me getting emotional over a return value 😭

lowkey reminder: failure means a negative error code, not vibes. check it, bestie. 🔥
