103 4. Regulator Current Limit Control & Status (dynamic drivers)
107 current limit to match system operating points. e.g. LCD backlight driver can
108 change the current limit to vary the backlight brightness, USB drivers may want
109 to set the limit to 500mA when supplying power.
111 Consumers can control their supply current limit by calling::
115 Where min_uA and max_uA are the minimum and maximum acceptable current limit in
120   when enabled, then the current limit changes instantly, otherwise the current
121   limit configuration changes and the current limit is physically set when the
124 A regulators current limit can be found by calling::
129   get_current_limit() will return the current limit whether the regulator
130   is enabled or disabled and should not be used to determine regulator current
139 changes. e.g. consumer driver is idle and subsequently draws less current
