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.

Annotated Snippet

config GP_PCI1XXXX
       tristate "Microchip PCI1XXXX PCIe to GPIO Expander + OTP/EEPROM manager"
       depends on PCI
       depends on GPIOLIB
       depends on NVMEM_SYSFS
       select GPIOLIB_IRQCHIP
       select AUXILIARY_BUS
       help
         PCI1XXXX is a PCIe GEN 3 switch with one of the endpoints having
         multiple functions and one of the functions is a GPIO controller
         which also has registers to interface with the OTP and EEPROM.
         Select yes, no or module here to include or exclude the driver
         for the GPIO function.

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.
