4.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marcin Wojtas <mw@xxxxxxxxxxxx>
commit ad715b268a501533ecb2e891a624841d1bb5137c upstream.
Armada CP110 system controller comprises its own routine responsble
for registering gate clocks. Among others 'flags' field in
struct clk_init_data was not set, using a random values, which
may cause an unpredicted behavior.
This patch fixes the problem by resetting all fields of clk_init_data
before assigning values for all gated clocks of Armada 7k/8k SoCs family.
Fixes: d3da3eaef7f4 ("clk: mvebu: new driver for Armada CP110 system ...")
