13*4882a593Smuzhiyun  This module is part of the sl28cpld multi-function device. For more
14*4882a593Smuzhiyun  details see ../mfd/kontron,sl28cpld.yaml.
15*4882a593Smuzhiyun
16*4882a593Smuzhiyun  The controller supports one PWM channel and supports only four distinct
17*4882a593Smuzhiyun  frequencies (250Hz, 500Hz, 1kHz, 2kHz).
