| |
According to lp8727 bindings[*], charging parameter is optional. So parsing can be skipped in case those properties are undefined. However, 'debounce-ms' should be read prior to checking the properties. Otherwise, 'debounce-ms' property will be ignored even it is configured inside the DT. So, counting child is processed after updating 'debounce-ms'.
