This patch series adds support in clock framework for clocks which operations
requires its parent clock is on.

Such clock type is initially met on Freescale i.MX7D platform that all clocks
operations, including enable/disable, rate change and re-parent, requires its
parent clock on. No sure if any other SoC has the similar clock type.

Current clock core can not support such type of clock well.

This patch introduce a new flag CLK_SET_PARENT_ON to handle this special case
in clock core that enable its parent clock firstly for each operation and disable
it later after operation complete.

The most special case is for set_parent() operation which requires both parent,
old one and new one, to be enabled at the same time during the operation.

The patch series is based on for-next branch of Michael's git:
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git
Do you plan to resend this series?
It is in my TODO list.
I'm currently busy with some other items.
Will be able to do it in a few days.

Regards
Dong Aisheng
