From 4f4fc993db4cd074fb2b51586dadd10e882604ec Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Fri, 26 Jan 2018 23:36:50 +0100 Subject: [PATCH] base-files: add more name source to get_dt_led helper function Not all LED driver are using the label devicetree property for the led name. Add support for the TI/National Semiconductor LP55xx Led Drivers, which are using the chan-name property for the led name, as fallback.
