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 Acked-by: Chris Ball <cjb@laptop.org> # for msm_sdcc.c Signed-off-by: Olof Johansson <olof@lixom.net>
