From 3e5dd6f6e690048d0fd1c913397506648724474e Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 26 Feb 2016 16:54:31 +0100 Subject: [PATCH] clk: Ignore disabled DT clock providers of_clk_init() uses for_each_matching_node_and_match() to find clock providers, which returns all matching device nodes, whether they are enabled or not. Hence clock providers that are disabled explicitly in DT using e.g. "status = "disabled"; are still activated. Add a check to ignore device nodes that are not enabled, like of_irq_init() does.
