+ 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.
