[PATCH v2 02/15] clk: divider: fix initialization with parent_hw

[Michael Tretter]

If a driver registers a divider clock with a parent_hw instead of the
parent_name, the parent_hw is ignored and the clock does not have a
parent.

Fix this by initializing the parents the same way they are initialized
for clock gates.
