From 8f3156f3f2b70128b2761526c208c8e3bfda694e Mon Sep 17 00:00:00 2001

Subject: [PATCH] clk: sunxi: add names for pll5, pll6 parent clocks to
factors_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Some factor clocks, such as the parent clock of pll5 and pll6, have
multiple output names. Add the corresponding names to factors_data
tied to compatible string.
