OF_PWM_GET(9)                      Pulse-Width Modulation (PWM)                     OF_PWM_GET(9)



NAME
       of_pwm_get - request a PWM via the PWM framework

SYNOPSIS
       struct pwm_device * of_pwm_get(struct device_node * np, const char * con_id);

ARGUMENTS
       np
           device node to get the PWM from

       con_id
           consumer name

DESCRIPTION
       Returns the PWM device parsed from the phandle and index specified in the “pwms” property
       of a device tree node or a negative error-code on failure. Values parsed from the device
       tree are stored in the returned PWM device object.

       If con_id is NULL, the first PWM device listed in the “pwms” property will be requested.
       Otherwise the “pwm-names” property is used to do a reverse lookup of the PWM index. This
       also means that the “pwm-names” property becomes mandatory for devices that look up the
       PWM device via the con_id parameter.

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