-        bool "Use IRQ priority"
-        help
-          Select this if you want to use prioritized IRQ handling.
-          This feature prevents higher priority ISR to be interrupted
-          by lower priority IRQ.
-          This may be useful in embedded applications, where are strong
-          requirements for timing.
-          Say N here, unless you have a specialized requirement.
