This patch adds a driver to manage 15 and access global utilities block for LoongArch architecture Loongson-2 16 SoCs. Initially only reading SVR and registering soc device are 17 supported. Other guts accesses, such as reading firmware configuration 18 by default, should eventually be added into this driver as well. 19 20config LOONGSON2_PM 21 bool "Loongson-2 SoC Power Management Controller Driver" 22 depends on LOONGARCH && OF 23 depends on INPUT=y 24 help 25 The Loongson-2's power management controller was ACPI, supports ACPI 26 S2Idle (Suspend To Idle), ACPI S3 (Suspend To RAM), ACPI S4 (Suspend To 27 Disk), ACPI S5 (Soft Shutdown) and supports multiple wake-up methods 28 (USB, GMAC, PWRBTN, etc.). This driver was to add power management 29 controller support that base on dts for Loongson-2 series SoCs. 30
