I have the GDSC support patches done on top. Will post once I 
get some reasonable testing done.

[PATCH 0/5] Add support for MSM8996 clock controllers

2015-11-17 Thread Stephen Boyd 
These patches add support for the global and multimedia clock controllers
found on MSM8996 devices. The first patch allows us to implement a
"power of two" divider of different widths with a table based divider.
The second patch adds support for Alpha PLLs and the 3rd and 5th patches
add support for the two clock controllers. The fourth patch is
a new type of clock ops for the graphics clock that does some custom
ping-pong between different PLLs when switching graphics frequencies.

Some work is still pending, mostly adding GDSCs and configuring the
multimedia PLLs for FSM voting mode vs. manually enabling and
disabling them. So a v2 is probably going to come out after
some more testing is done.
