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.

config LOONGSON2_GUTS
tristate "Loongson-2 SoC Global UtiliTieS (GUTS) register block"
depends on LOONGARCH || COMPILE_TEST
select SOC_BUS
help
The global utilities block controls PCIE device enabling, alternate
function selection for multiplexed signals, consistency of HDA, USB
and PCIE, configuration of memory controller, rtc controller, lio
controller, and clock control. This patch adds a driver to manage
and access global utilities block for LoongArch architecture Loongson-2
SoCs. Initially only reading SVR and registering soc device are
supported. Other guts accesses, such as reading firmware configuration
by default, should eventually be added into this driver as well.

bool "Loongson-2 SoC Power Management Controller Driver"
depends on LOONGARCH && OF
depends on INPUT=y
help
The Loongson-2's power management controller was ACPI, supports ACPI
S2Idle (Suspend To Idle), ACPI S3 (Suspend To RAM), ACPI S4 (Suspend To
Disk), ACPI S5 (Soft Shutdown) and supports multiple wake-up methods
(USB, GMAC, PWRBTN, etc.). This driver was to add power management
controller support that base on dts for Loongson-2 series SoCs.
Annotation
- Atlas domain: Driver Families / drivers/soc.
- Implementation status: atlas-only.
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.
