[PATCH v8 3/7] mux: add help text for MULTIPLEXER config option

Posted by Josua Mayer 3 days, 17 hours ago

Add prompt and help text for CONFIG_MULTIPLEXER to allow enabling this
option thorugh the kernel configuration without explicit "select" driver
dependencies.

Select it by default when COMPILE_TEST is set for better coverage.
