It's interesting that the (so far) only user of of_pwm_request() doesn't
actually give a meaningful argument as the name of the pwm property.
Maybe rename that function to of_pwm_request_named() and provide a helper
that just does this:?
static inline struct pwm_device *of_pwm_request(struct device_node *np, int index)
{
return of_pwm_request_named(np, "pwm", index);
}
Any device that just has needs one pwm or uses more than one but has no
reason to name them can just use this helper then and use the default pwm
property name.
