aspeed_g5_sig_expr_set(9) 💖 Kernel API Manual energy

okay bestie, we're in the pinmux corner of the kernel and this page is literally about configuring a pin's signal through an expression. no cap, let's get into it 🎀

🌸 NAME 🌸

aspeed_g5_sig_expr_set — configure a pin's signal by applying an expression's descriptor state for all descriptors in the expression. that's the whole vibe: one expression, all its descriptors, state applied ✨

✨ SYNOPSIS ✨

int aspeed_g5_sig_expr_set (struct aspeed_pinmux_data *ctx , const
       struct aspeed_sig_expr *expr , bool enable );

🎀 ARGUMENTS 🎀

• ctx — the pinmux context. that's the context bestie, you gotta pass it 🫶
• expr — the expression associated with the function whose signal is to be configured. it's giving "the actual expression in question" 💅
• enable — true to enable an function's signal through a pin's signal expression, false to disable the function's signal. yes, literally true versus false, iconic 🔥

🔥 RETURN 🔥

returns 0 if the expression is configured as requested, and a negative error code otherwise. no cap, negative means something went sideways 😭
