From fda7cbfefd44448dc275508942b59fb38480c156 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Tue, 1 Mar 2022 09:10:59 +0100 Subject: [PATCH] power: zynqmp: Use zynqmp_pmufw_node() from firmware Remove private xpm_configobject[] and use zynqmp_pmufw_node() which provides the same functionality. Also add debug messages for easier debugging.
