clk: remove COMMON_CLK_DISABLE_UNUSED

2012-05-08T21:12:42+00:00

Exposing this option generates confusion and incorrect behavior for single-image builds across platforms. Enable this behavior permanently. Signed-off-by: Mike Turquette Acked-by: Saravana Kannan

clk: select CLKDEV_LOOKUP for COMMON_CLK

2012-04-24T23:37:41+00:00

Using the common clock infrastructure without the common clkdev code makes little sense, so select CLKDEV_LOOKUP for COMMON_CLK. Signed-off-by: Rob Herring

clk: make CONFIG_COMMON_CLK invisible

2012-03-19T09:37:11+00:00

All platforms that use the common clk infrastructure should select COMMON_CLK from platform code, and on all other platforms, it must not be enabled, so there is no point making the option visible to users, and when it is visible, we break randconfig builds. Signed-off-by: Arnd Bergmann

clk: introduce the common clock framework

2012-03-16T20:35:01+00:00

The common clock framework defines a common struct clk useful across most platforms as well as an implementation of the clk api that drivers can use safely for managing clocks. The net result is consolidation of many different struct clk definitions and platform-specific clock framework implementations. This patch introduces the common struct clk, struct clk_ops and an implementation of the well-known clock api in include/clk/clk.h. Platforms may define their own hardware-specific clock structure and their own clock operation callbacks, so long as it wraps an instance of struct clk_hw. See Documentation/clk.txt for more details. This patch is based on the work of Jeremy Kerr, which in turn was based on the work of Ben Herrenschmidt.

clk: add config option HAVE_CLK_PREPARE into Kconfig

2011-12-28T13:35:06+00:00

The commit 40d3e0f (clk: provide prepare/unprepare functions) provides the config option HAVE_CLK_PREPARE for platforms that have prepare/unprepare implementation to select. This patch adds the option into drivers/clk/Kconfig, so that it can be actually selected. Signed-off-by: Shawn Guo Cc: Russell King

ARM: Consolidate the clkdev header files

2011-07-19T16:09:45+00:00

Now most of ARM machines has the alsmot same __clk_get/put() macro So place it at the arch/arm/include/asm/clkdev.h and remove the reduntant header files But some machines don't have the same form as above. It can use the machince specific clkdev file by HAVE_MACH_CLKDEV config Now there are only 3 caese. 1) define the clk structure with clkdev macro => Need to move clk structure to proper header file arch/arm/mach-versatile/include/mach/clkdev.h arch/arm/mach-realview/include/mach/clkdev.h arch/arm/mach-vexpress/include/mach/clkdev.h arch/arm/mach-integrator/include/mach/clkdev.h 2) export the __clk_get/put function at clock.c arch/arm/mach-shmobile/include/mach/clkdev.h 3) demuxing the clk source arch/arm/mach-u300/include/mach/clkdev.h Acked-by: Viresh Kumar Acked-by: H Hartley Sweeten Acked-by: Jean-Christophe PLAGNIOL-VILLARD Signed-off-by: Kyungmin Park

ARM: 6483/1: arm & sh: factorised duplicated clkdev.c

2010-11-26T10:51:04+00:00

factorise some generic infrastructure to assist looking up struct clks for the ARM & SH architecture. as the code is identical at 99% put the arch specific code for allocation as example in asm/clkdev.h Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD Acked-by: Paul Mundt Signed-off-by: Russell King
