SYNOPSIS

struct pwm_device * pwm_get(struct device * dev, const char * con_id);

ARGUMENTS

dev

device for PWM consumer

con_id

consumer name

DESCRIPTION

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.

RETURNS

A pointer to the requested PWM device or an ERR_PTR-encoded error code on failure.
