MSM clock updates for 3.11.

Browse source 
Per Stephen Boyd's coverletter:
 
 Resending to collect higher level maintainer acks per Olof's request.
 The plan is to push this patchset through MSM to the arm-soc tree.
 
 This patchset moves the existing MSM clock code and affected drivers
 to the common clock framework. A prerequisite of moving to the common
 clock framework is to use clk_prepare() and clk_enable() so the first
 few patches migrate drivers to that call (clk_prepare() is a no-op on
 MSM right now). It also removes some custom clock APIs that MSM
 provides and finally moves the proc_comm clock code to the common
 struct clk.
 
 This patch series will be used as the foundation of the MSM 8660/8960
 clock code that I plan to send out after this series.

Merge tag 'msm-clock-for-3.11b' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/late

From David Brown:
MSM clock updates for 3.11.

Per Stephen Boyd's coverletter:

Resending to collect higher level maintainer acks per Olof's request.

This patchset moves the existing MSM clock code and affected drivers

struct clk.

This patch series will be used as the foundation of the MSM 8660/8960
clock code that I plan to send out after this series.
