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.
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.

* tag 'msm-clock-for-3.11b' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm:
  ARM: msm: Migrate to common clock framework
  ARM: msm: Make proc_comm clock control into a platform driver
  ARM: msm: Prepare clk_get() users in mach-msm for clock-pcom driver
  ARM: msm: Remove clock-7x30.h include file
  ARM: msm: Remove custom clk_set_{max,min}_rate() API
  ARM: msm: Remove custom clk_set_flags() API
  msm: iommu: Use clk_set_rate() instead of clk_set_min_rate()
  msm: iommu: Convert to clk_prepare/unprepare
  msm_sdcc: Convert to clk_prepare/unprepare
  usb: otg: msm: Convert to clk_prepare/unprepare
  msm_serial: Use devm_clk_get() and properly return errors
  msm_serial: Convert to clk_prepare/unprepare
