Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

• Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Touches IRQ or DMA behavior; this matters for the representative real-device path.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

• Immediate include surface: `linux/module.h`, `linux/device.h`, `linux/console.h`, `linux/serial_core.h`, `linux/serial.h`, `linux/clk.h`, `linux/io.h`, `linux/tty.h`.
• Detected declarations: `struct clps711x_port`, `function uart_clps711x_stop_tx`, `function uart_clps711x_start_tx`, `function uart_clps711x_int_rx`, `function uart_clps711x_int_tx`, `function uart_clps711x_tx_empty`, `function uart_clps711x_get_mctrl`, `function uart_clps711x_set_mctrl`, `function uart_clps711x_break_ctl`, `function uart_clps711x_set_ldisc`.
• Atlas domain: Driver Families / drivers/tty.
• Implementation status: integration implementation candidate.
• IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
