From 312dd1c55cbb4f090a1f3ba25709779550c0f50c Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Thu, 2 Aug 2018 12:58:54 +0200 Subject: [PATCH] gpio: xilinx: Add support for using label property Add support for reading label property from DT and set up bank name based on that. If label property is not present full device node name is used.
