Subject: [PATCH 4.16 044/272] ARM: dts: sun4i: Fix incorrect clocks for displays

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

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

From: Pascal Roeleven <dev@...calroeleven.nl>

commit 590b0c0cfc6162aeebbf43eaafb9753b56df1532 upstream.

Some displays on sun4i devices wouldn't properly stay on unless
'clk_ignore_unused' is used.

Change the duplicate clocks to the probably intended ones.
