Currently everyone re-invents their own clock tree inside platform code which makes it impossible for drivers to use the clock APIs safely across many platforms and for distro's to compile multi-platform kernels which all redefine struct clk and its operations. This is the second version of the common clock patches which were originally posted by Jeremy Kerr and then re-posted with some additional patches by Mark Brown. Mark's re-post didn't have any changes done to the original four patches from Jeremy which is why this series is "v2". The changes in this series are minimal: I've folded in some of Mark's fixes and most of the comments posted to his series as well as rebasing on top of v3.1-rc7. The design and functionality hasn't changed much since Jeremy posted v1 of this series. Propagating the rate change up to the parent has been removed from clk_set_rate since that needs some more thought. I also dropped Mark's change to append a device's name to a clk name since device tree might solve this neatly. Again more discussion around that would be good. v1 of the series can be found at, http://article.gmane.org/gmane.linux.kernel/1143182 Mark's re-post (v1+) can be found at, http://article.gmane.org/gmane.linux.ports.arm.kernel/129889 Todo in follow-up patches: clk_set_parent Implement a *safe* upstream propagation for parent rate changes Track tree topology and export to userspace (sysfs or debugfs) Manage root clocks globally Device tree support Per-tree locking instead of framework-wide locking Device driver rate-change notifiers Jeremy Kerr (4): clk: Add a generic clock infrastructure clk: Implement clk_set_rate clk: Add fixed-rate clock clk: Add simple gated clock Mark Brown (3): clk: Add Kconfig option to build all generic clk drivers clk: Add initial WM831x clock driver x86: Enable generic clk API on x86 MAINTAINERS | 1 + arch/x86/Kconfig | 1 + drivers/clk/Kconfig | 27 +++- drivers/clk/Makefile | 4 + drivers/clk/clk-fixed.c | 24 +++ drivers/clk/clk-gate.c | 78 ++++++++++ drivers/clk/clk-wm831x.c | 386 ++++++++++++++++++++++++++++++++++++++++++++++ drivers/clk/clk.c | 291 ++++++++++++++++++++++++++++++++++ drivers/clk/clkdev.c | 7 + include/linux/clk.h | 179 ++++++++++++++++++++-- 10 files changed, 985 insertions(+), 13 deletions(-) create mode 100644 drivers/clk/clk-fixed.c create mode 100644 drivers/clk/clk-gate.c create mode 100644 drivers/clk/clk-wm831x.c create mode 100644 drivers/clk/clk.c -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
