config POLARFIRE_SOC_IRQ_MUX bool "Microchip PolarFire SoC's GPIO IRQ Mux" depends on ARCH_MICROCHIP select REGMAP select REGMAP_MMIO default y help Support for the interrupt mux on Polarfire SoC. It sits between the GPIO controllers and the PLIC, as only 41 interrupts are shared between 3 GPIO controllers with a total of 70 interrupts. config POLARFIRE_SOC_SYS_CTRL tristate "Microchip PolarFire SoC (MPFS) system controller support" depends on POLARFIRE_SOC_MAILBOX depends on MTD help This driver adds support for the PolarFire SoC (MPFS) system controller. To compile this driver as a module, choose M here. the module will be called mpfs_system_controller. If unsure, say N. config POLARFIRE_SOC_SYSCONS bool "PolarFire SoC (MPFS) syscon drivers" default y depends on ARCH_MICROCHIP select MFD_CORE help These drivers add support for the syscons on PolarFire SoC (MPFS). Without these drivers core parts of the kernel such as clocks and resets will not function correctly. If unsure, and on a PolarFire SoC, say y.
