pwm_get - look up and request a PWM device
struct pwm_device * pwm_get(struct device * dev, const char * con_id);
Lookup is first attempted using DT. If the device was not instantiated from a device tree, a PWM chip and a relative index is looked up via a table supplied by board setup code (see pwm_add_table).
Once a PWM chip has been found the specified PWM device will be requested and is ready to be used.
A pointer to the requested PWM device or an ERR_PTR-encoded error code on failure.
