Linux kernel Kconfig: How can I deselect an option












0















How do I de-select an option?
For example, the following script is what I want to achieve:



choice                                                                                         
prompt "Camera type"
default CAMERA1

config CAMERA1
select POWER_PIN_ACTIVE_HIGH

config CAMERA2
deselect POWER_PIN_ACTIVE_HIGH

config CAMERA3
select POWER_PIN_ACTIVE_HIGH

endchoice

config POWER_PIN_ACTIVE_HIGH
bool "Power pin is high active?"
help Say 'y' if the power pin is high active, 'n' if low active.


Apparently, there is no de-select command, or even select XXXX = n command.



Howe do I achieve the effect?
