Subject: [PATCH] clk: sunxi: get divs parent clock name from parent factor
 clock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Divs clocks consist of a parent factor clock with multiple outputs,
and seperate clocks for each output. Get the name of the parent
clock from the parent factor clock, instead of the DT node name.
