I think the easiest way to Yeah, your pointing out is correct, but in this case, it should be 'bool' not 'tristate' because the PWM driver cannot support module now. > solve this problem would be to add a default line, like so: > > default PLAT_SAMSUNG > > I've checked this with a s3c2410_defconfig and this causes PWM_SAMSUNG > to be selected =y, which I guess is what you want. > How do you think following, just adding from original one? - tristate "Samsung pwm support" + bool "SAMSUNG PWM support" Thanks.
