2011-12-28clk: add config option HAVE_CLK_PREPARE into KconfigShawn Guo1-0/+3
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 <shawn.guo@linaro.org> Cc: Russell King <rmk+kernel@arm.linux.org.uk>
2011-07-19ARM: Consolidate the clkdev header filesKyungmin Park1-0/+3
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 <viresh.kumar@st.com> Acked-by: H Hartley Sweeten <hsweeten@visionengravers.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2011-04-30CLKDEV: Fix clkdev return value for NULL clk caseRussell King1-10/+9
clkdev may incorrectly cause a clkdev entry with a NULL clk to return -ENOENT. This is not the intention of this code; -ENOENT should only be returned if the clock entry can not be found in the table. Fix this.

2010-11-26ARM: 6483/1: arm & sh: factorised duplicated clkdev.cJean-Christop PLAGNIOL-VILLARD3-0/+182
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 <plagnioj@jcrosoft.com> Acked-by: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
