Thanks Nick for the reply

Actually I know the document. But what I need is a way through which I can access the driver in another platform driver . For eg

I have created aplatfor driver xyz, which requires initializing of the PWM for which I have made entries in DTS

Now inside xyz I need to use API such as pwm_request or pwm_get to get device handle.

I need such example

In short , my /sys/class/pwm---has pwmchip0 and pwmchip2.

If I try to use above mentioned API,pwm_request(int pwm, const char *label),

what should be the int pwm and label

Request you to please provide some example for this
