STRUCT TEGRA_UART_CHIP_DATA(9)

💅 struct tegra_uart_chip_data(9) — the kernel API manual, but make it make sense

okay so bestie, you're looking at the struct tegra_uart_chip_data(9) page from the Kernel API Manual. it's short, it's sweet, and it's literally just a lil bundle of SOC-specific data. per SOC. for the Tegra UART driver. that's the whole vibe. let's go ✨

---

🌸 NAME 🌸

struct tegra_uart_chip_data — SOC specific data. that's it, that's the whole name. no cap 🫶

---

🎀 SYNOPSIS 🎀

here's the struct in all its glory, copy it exactly bestie, character for character:

struct tegra_uart_chip_data {
    bool tx_fifo_full_status;
    bool allow_txfifo_reset_fifo_mode;
    bool support_clk_src_div;
    bool fifo_mode_enable_status;
    int uart_max_port;
    int max_dma_burst_bytes;
    int error_tolerance_low_range;
    int error_tolerance_high_range;
 };

four bools, four ints, zero drama. iconic honestly 👑

🦋 Members 🦋

okay so let's go member by member, because every single one matters and i'm not skipping a single one of them 💖

• tx_fifo_full_status — a status flag that's actually available for checking whether the tx fifo is full. so like, you can check it. that's the whole point of the flag fr fr.
• allow_txfifo_reset_fifo_mode — tells you whether resetting the tx fifo with fifo mode is allowed or not. and heads up: Tegra30 does not allow this. lowkey important, don't forget it 🙈
• support_clk_src_div — the clock source supports the clock divider. that's the situation.
• fifo_mode_enable_status — is FIFO mode enabled? that's literally the question this answers. vibe check for fifo mode 💀
• uart_max_port — the maximum number of UART ports. more ports, more main character energy.
• max_dma_burst_bytes — the maximum size of DMA bursts. big bursts, big slay 🔥
• error_tolerance_low_range — the lowest number in the error tolerance range. the floor of it, basically.
• error_tolerance_high_range — the highest number in the error tolerance range. the ceiling. together they're giving very "bookends" 🌈
