2016-06-03ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIBLinus Walleij1-1/+1
This replaces: - "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can now be selected directly. - "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB is now selectable by everyone, so we need not declare our intent to select it. When ordering the symbols the following rationale was used: if the selects were in alphabetical order, I moved select GPIOLIB to be in alphabetical order, but if the selects were not maintained in alphabetical order, I just replaced "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

2014-06-17ARM: Remove ARCH_HAS_CPUFREQ config optionStephen Boyd1-1/+0
This config exists entirely to hide the cpufreq menu from the kernel configuration unless a platform has selected it. Nothing is actually built if this config is 'Y' and it just leads to more patches that add a select under a platform Kconfig so that some other CPUfreq option can be chosen. Let's remove the option so that we can always enable CPUfreq drivers on ARM platforms.

To allow consolidation of DT driven .time_init, move of_clock_init() to a temporary .time_init callback that will be removed when arch-wide callback is available.

2013-05-20ARM: vt8500: Add missing NULL terminator in dt_compatSrinivas Kandagatla1-0/+1
When I tried booting a stih415 Dual core A9 with multi_v7_defconfig, it failed to boot. The issues seems to be changing by enabling or disabling VT8550 platform. Having a quick look at dt_compat list, it seems to miss a NULL terminator, which means of_flat_dt_match will compat check will cross the boundary of dt_compat and fault at some point , which is what was happening in my case. Without this patch if we try to boot multi_v7_defconfig you might notice that some of the platforms might fault if they fall after vt8500 in machine-desc list. Other platforms which fall before vt8500 in mdesc list will not fault.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM soc multiplatform enablement from Olof Johansson: "This is a pretty significant branch. It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while. Sorry for the overhead."

2012-09-21arm: vt8500: Update arch-vt8500 to devicetree support.Tony Prisk19-1546/+400
Merged existing board files to a single dt-capable file. Converted irq and timer code to devicetree. Removed existing device files that are no longer required with devicetree support. All existing platform devices are converted to devicetree nodes except PWM. Removed restart.c and moved code into vt8500.c to remove duplicate PMC code.

2012-09-14ARM: make mach/gpio.h headers optionalRob Herring1-1/+0
Most platforms don't need mach/gpio.h and it prevents multi-platform kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX or have lots of implicit includes pulled in by mach/gpio.h. at91 and omap have gpio clean-up pending and can drop CONFIG_NEED_MACH_GPIO_H once that is in.

2012-07-30Merge branch 'for-3.6' of git://gitorious.org/linux-pwm/linux-pwmLinus Torvalds2-267/+0
Pull PWM subsystem from Thierry Reding: "The new PWM subsystem aims at collecting all implementations of the legacy PWM API and to eventually replace it completely. The subsystem has been in development for over half a year now and many drivers have already been converted. It has been in linux-next for a couple of weeks and there have been no major issues so I think it is ready for inclusion in your tree." Arnd Bergmann <arnd@arndb.de>: "Very much Ack on the new subsystem. It uses the interface declarations as the previously separate pwm drivers, so nothing changes for now in the drivers using it, although it enables us to change those more easily in the future if we want to. This work is also one of the missing pieces that are required to eventually build ARM kernels for multiple platforms, which is currently prohibited (amongs other things) by the fact that you cannot have more than one driver exporting the pwm functions."
