STRUCT GPI_SPI_CONFIG(9)

okay bestie, welcome to the struct gpi_spi_config(9) page from the Kernel API Manual 💖 this one is literally the spi config for a peripheral struct, and it's giving kernel struct realness. we're walking every member like a fit check, no skips, periodt. 💅

💖 NAME 💖

struct gpi_spi_config — spi config for peripheral, no cap. 🎀

✨ SYNOPSIS ✨

here's the whole struct layout, copied exactly so you can trust it:

       struct gpi_spi_config {
           u8 set_config;
           u8 loopback_en;
           u8 clock_pol_high;
           u8 data_pol_high;
           u8 pack_en;
           u8 word_len;
           u8 fragmentation;
           u8 cs;
           u32 clk_div;
           u32 clk_src;
           enum spi_transfer_cmd cmd;
           u32 rx_len;
        };

🫶 Members 🫶

every field, in order, with zero skips:

• set_config — sets the peripheral config. ✨
• loopback_en — spi loopback enable when it's set. 🔁
• clock_pol_high — clock polarity. 🕰️
• data_pol_high — data polarity. 🎀
• pack_en — processes tx/rx buffers as packed. 📦
• word_len — spi word length. 🔤
• fragmentation — keeps CS asserted at the end of the sequence. 📌
• cs — chip select toggle. 👆
• clk_div — source clock divider. ➗
• clk_src — serial clock. ⏰
• cmd — spi cmd. 🫡
• rx_len — receive length for buffer. 📥
