[PATCH v1 25/28] leds: lt3593: Make use of device properties

From: Andy Shevchenko
Date: Mon May 10 2021 - 05:53:25 EST


From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

Device property API allows to gather device resources from different sources,
such as ACPI. Convert the driver to unleash the power of device property API.
