STRUCT CAS_CONTROL(9)

💅 struct cas_control(9) 💅

okay so this is the Kernel API Manual entry for struct cas_control, and it is literally the little backpack 🎒 that carries all the spi-exchange stuff around. no cap, it's giving “one exchange, one vibe.”

🌸 NAME 🌸

struct cas_control — spi transfer structure 💖

✨ SYNOPSIS ✨

struct cas_control {
    struct spi_message msg;
    struct spi_transfer transfer;
    u8 tx_buf[CA8210_SPI_BUF_SIZE];
    u8 tx_in_buf[CA8210_SPI_BUF_SIZE];
    struct ca8210_priv *priv;
};

🎀 Members 🎀

• msg — the spi_message for each exchange, bestie ✨
• transfer — the spi_transfer for each exchange 💅
• tx_buf — source array for transmission, main character energy 🔥
• tx_in_buf — array storing bytes received during transmission 🌸
• priv — pointer to private data, iykyk 🦋

🧚 Description 🧚

okay so this structure is literally storing all the necessary data that gets passed around during a single spi exchange. that's the whole vibe: one exchange, all the stuff it needs, packed together 💖. no extra lore, fr fr.
