A read-only pwmN_enable file doesn't necessarily mean that the driver is broken. The device might as well support only one control mode and the only way to let user-space know what it is is to create a read-only pwmN_enable file. So I had pwmconfig simply skip PWM outputs that it cannot control. I have also submitted two patches yesterday that fix the lm85 driver so that it finally works correctly with pwmconfig. Please test if you can. -- Jean Delvare
