STRUCT S3C64XX_SPI_INFO(9)

okay bestie, buckle up 🫶 this is struct s3c64xx_spi_info(9) from the Kernel API Manual — the SPI Controller defining structure, and it's lowkey iconic. We're doing a full vibe check on every member, no skipping, periodt 💅✨

💖 NAME 💖

struct s3c64xx_spi_info — SPI Controller defining structure. That's the name, that's the energy, and yes it ate 🎀

✨ SYNOPSIS ✨

Here's the struct in all its exact character-for-character glory, bestie — do not touch the commas or semicolons, fr fr:

struct s3c64xx_spi_info {
    int src_clk_nr;
    int num_cs;
    bool no_cs;
    bool polling;
    int (*cfg_gpio)(void);
 };

🎀 Members 🎀

• src_clk_nr — Clock source index for the CLK_CFG[SPI_CLKSEL] field. It's literally telling the clock config where to look, iykyk ⭐
• num_cs — Number of CS this controller emulates. So that's how many chip-selects we're serving, no cap 💅
• no_cs — Used when CS line is not connected. If the CS line is doing its own thing (or not connected at all), this is the flag for that vibe 🙈
• polling — Using polling mode when true (no 'dmas' property in devicetree). When it's true, we're polling; and the parenthetical is the devicetree tea: there's no 'dmas' property 🍓
• cfg_gpio — Configure pins for this SPI controller. This is the function pointer that handles the pin setup, main character energy for GPIO config 👑
