[PATCH 4.8 18/57] clk: mvebu: fix setting unwanted flags in CP110 gate clock

[Greg Kroah-Hartman]

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marcin Wojtas <m...@semihalf.com>

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.
