The first patch just removes some unneeded NULL checks. The second removes __clk_register. The third patch actually moves the per-clock data that was stored in struct clk to a new struct clk_core and adds references to it from both struct clk and struct clk_hw. struct clk is now ready to contain information that is specific to a given clk consumer. The fourth patch adds API for setting floor and ceiling constraints and stores that information on the per-user struct clk, which is iterable from struct clk_core. The constraints are made available to clock implementations in the determine_rate callback. The fifth patch exports clk_register_clkdev so that clk-test.ko can be built as a module. The sixth patch adds a module that can be used to unit-test the CCF. It's very rough right now, but I hope to have time soon to polish it a bit. It has been quite useful during development of this series though. http://cgit.collabora.com/git/user/tomeu/linux.git/log/?h=per-user-clk-constraints-v13 Thanks, Tomeu Tomeu Vizoso (6): clk: Remove unneeded NULL checks clk: Remove __clk_register clk: Make clk API return per-user struct clk instances clk: Add rate constraints to clocks clkdev: Export clk_register_clkdev clk: Add module for unit tests Documentation/clk.txt | 2 + arch/arm/mach-omap2/cclock3xxx_data.c | 111 +++-- arch/arm/mach-omap2/clock.h | 11 +- arch/arm/mach-omap2/clock_common_data.c | 5 +- arch/arm/mach-omap2/dpll3xxx.c | 2 + arch/arm/mach-omap2/dpll44xx.c | 2 + arch/mips/alchemy/common/clock.c | 8 + drivers/clk/Kconfig | 1 + drivers/clk/Kconfig.debug | 6 + drivers/clk/Makefile | 1 + drivers/clk/at91/clk-programmable.c | 2 + drivers/clk/bcm/clk-kona.c | 2 + drivers/clk/clk-composite.c | 9 +- drivers/clk/clk-test.c | 326 ++++++++++++ drivers/clk/clk.c | 851 +++++++++++++++++++++----------- drivers/clk/clk.h | 5 + drivers/clk/clkdev.c | 85 +++- drivers/clk/hisilicon/clk-hi3620.c | 2 + drivers/clk/mmp/clk-mix.c | 2 + drivers/clk/qcom/clk-pll.c | 1 + drivers/clk/qcom/clk-rcg.c | 10 +- drivers/clk/qcom/clk-rcg2.c | 6 + drivers/clk/sunxi/clk-factors.c | 2 + drivers/clk/sunxi/clk-sun6i-ar100.c | 2 + include/linux/clk-private.h | 43 +- include/linux/clk-provider.h | 27 +- include/linux/clk.h | 28 ++ include/linux/clk/ti.h | 4 + 28 files changed, 1187 insertions(+), 369 deletions(-) create mode 100644 drivers/clk/Kconfig.debug create mode 100644 drivers/clk/clk-test.c -- 1.9.3
