Subject: [RESEND PATCH 0/3] Add Qualcomm MSM8939 GCC binding and driver

These three patches add support for the MSM8939 Global Clock Controller.
The MSM8939 is a derivation of the MSM8916 sharing the large majority of
its clock settings with MSM8916, however, there are enough changes, in some
cases mutually incompatible changes that necessitate a separate driver.

I thought it was both important and useful to show in the git log the
differences between MSM8916 and MSM8939 so, one patch copies the MSM8916
driver while another patch applies the entire gamut of MSM8939 changes,
squashing down from a git log of approximately 31 separate commits.

For reference that log is here:
https://github.com/bryanodonoghue/linux/pull/new/msm8939-clk-next-reference-log

Generally speaking MSM8939 differes from MSM8916 in two key ways.

- New and higher clock frequencies for existing IP blocks.
- New PLLs to drive those higher frequencies
