From 4462b4bbfc33a44f19710ead784ff361bda2c3b3 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Thu, 18 Feb 2016 19:07:44 -0800 Subject: clk: gpio: Really allow an optional clock= DT property We mis-merged the original patch from Russell here and so the patch went almost all the way, except that we still failed to probe when there wasn't a clocks property in the DT node. Allow that case by making a negative value from of_clk_get_parent_count() into "no parents", like the original patch did.
