si476x_core..._ctl_pin_cfg(9)

💅 si476x_core..._ctl_pin_cfg(9) ✨

okay so bestie, welcome to the Kernel API Manual — this one's a lil' function that sends the 'IC_LINK_GPIO_CTL_PIN_CFG' command straight to the device 🎀 and honestly? it's giving "let me rearrange my pins real quick" energy. no cap.

✨ SYNOPSIS ✨

int si476x_core_cmd_ic_link_gpo_ctl_pin_cfg (struct si476x_core *core ,
enum si476x_icin_config icin , enum si476x_icip_config icip , enum
si476x_icon_config icon , enum si476x_icop_config icop );

like, four enums and a core. that's the whole vibe check 🦋

🫶 ARGUMENTS 🫶

• core
  • the device you're sending the command to 💖 literally the main character here
• icin
  • the ICIN pin function configuration, and your options are:
  • SI476X_ICIN_NOOP — do not modify the behaviour 🙈
  • SI476X_ICIN_TRISTATE — put the pin in tristate condition, enable 1MOhm pulldown
  • SI476X_ICIN_GPO1_HIGH — set pin to be an output, drive it high 🔥
  • SI476X_ICIN_GPO1_LOW — set pin to be an output, drive it low
  • SI476X_ICIN_IC_LINK — set the pin to be a part of Inter-Chip link 🔗
• icip
  • the ICIP pin function configuration, same lineup but with a P:
  • SI476X_ICIP_NOOP — do not modify the behaviour 🙈
  • SI476X_ICIP_TRISTATE — put the pin in tristate condition, enable 1MOhm pulldown
  • SI476X_ICIP_GPO1_HIGH — set pin to be an output, drive it high 🔥
  • SI476X_ICIP_GPO1_LOW — set pin to be an output, drive it low
  • SI476X_ICIP_IC_LINK — set the pin to be a part of Inter-Chip link 🔗
• icon
  • the ICON pin function configuration, and bestie this one's different:
  • SI476X_ICON_NOOP — do not modify the behaviour 🙈
  • SI476X_ICON_TRISTATE — put the pin in tristate condition, enable 1MOhm pulldown
  • SI476X_ICON_I2S — set the pin to be a part of audio interface in slave mode (DCLK) 🎧
  • SI476X_ICON_IC_LINK — set the pin to be a part of Inter-Chip link 🔗
• icop
  • the ICOP pin function configuration:
  • SI476X_ICOP_NOOP — do not modify the behaviour 🙈
  • SI476X_ICOP_TRISTATE — put the pin in tristate condition, enable 1MOhm pulldown
  • SI476X_ICOP_I2S — set the pin to be a part of audio interface in slave mode (DOUT) [Si4761/63/65/67 Only] 👑 (like, read the fine print, it's a whole exclusive club)
  • SI476X_ICOP_IC_LINK — set the pin to be a part of Inter-Chip link 🔗

🌸 DESCRIPTION 🌸

so the function returns 0 on success and a negative error code on failure. that's it, that's the tea ☕ not me being obsessed with how simple it is tbh 💀

ngl bestie, always check that return value. negative number = it did NOT slay.
