CONFIG_RV32M1_INTMUX

OpenISA RV32M1 INTMUX interrupt controller support

Type: bool

Help

Select this option to enable support for the RV32M1 INTMUX
driver. This provides a level 2 interrupt controller for the SoC.
The INTMUX peripheral combines level 2 interrupts into
eight channels; each channel has its own level 1 interrupt to
the core.
