2014-03-21ARM: msm: avoid calling debug_ll_addr on !MMUArnd Bergmann
MSM7X00A has an open-coded version of debug_ll_io_init so it can use MT_DEVICE_NONSHARED as required by the platform. However, this fails to build on no-MMU kernels because the debug_ll_addr function is not available. Since the iotable_init function doesn't actually do anyting in this configuration, we can simply get away by enclosing the broken function call in an #ifdef, which seems to be the least ugly workaround.

2014-02-19Merge tag 'dropmachtimexh-v2' of git://git.pengutronix.de/git/ukl/linux into ↵Olof Johansson
next/cleanup This cleanup series gets rid of <mach/timex.h> for platforms not using ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since 387798b (ARM: initial multiplatform support).) To make this work some code out of arch/arm needed to be adapted. The respective changes got acks by their maintainers to be taken via armsoc (with Andrew Morton substituting for Alessandro Zummo as rtc maintainer). Compared to the previous pull request there was another patch added that fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not squash this fix into the original commit to save him from the need to reverify the series. * tag 'dropmachtimexh-v2' of git://git.pengutronix.de/git/ukl/linux: ARM: ixp4xx: fix timer latch calculation ARM: drop <mach/timex.h> for !ARCH_MULTIPLATFORM, too ARM: rpc: stop using <mach/timex.h> ARM: ixp4xx: stop using <mach/timex.h> input: ixp4xx-beeper: don't use symbols from <mach/timex.h> ARM: at91: don't use <mach/timex.h> ARM: ep93xx: stop using mach/timex.h ARM: mmp: stop using mach/timex.h ARM: netx: stop using mach/timex.h ARM: sa1100: stop using mach/timex.h clocksource: sirf/marco+prima2: drop usage of CLOCK_TICK_RATE rtc: pxa: drop unused #define TIMER_FREQ rtc: at91sam9: include <mach/hardware.h> explicitly ARM/serial: at91: switch atmel serial to use gpiolib Signed-off-by: Olof Johansson <olof@lixom.net>
2014-02-11ARM: qcom: Re-organize platsmp to make it extensibleRohit Vaswani
This makes it easy to add SMP support for new devices by keying on a device node for the release sequence. We add the enable-method property for the cpus property to specify that we want to use the gcc-msm8660 release sequence (which is going to look for the global clock controller device node to map some Scorpion specific power and control registers). We also remove the nr_cpus detection code as that is done generically in the DT CPU detection code.

There's a large number of various cleanups, and a nice net removal of 13500 lines of code. Highlights worth mentioning are: - A series of patches from Stephen Boyd removing the ARM local timer API. - Move of Qualcomm MSM IOMMU code to drivers/iommu. - Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver and switching over to the drivers/pwm one. - Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).

2013-08-27msm_serial: Switch clock consumer strings and simplify codeStephen Boyd
In downstream kernel we've standardized the clock consumer names that MSM device drivers use. Replace the uart specific clock names in this driver with the more standard 'core' and 'iface' names. Also simplify the code by assuming that clk_prepare_enable and clk_disable_unprepare() will properly check for NULL pointers (it will because MSM uses the common clock framework).

2013-08-06ARM: msm: Only compile io.c on platforms that use itStephen Boyd
Only the non-dt based MSM platforms need to map memory from their machine descriptor. Unfortunately it is always compiled if ARCH_MSM=y and the file also has mach/ includes in it. Since dt-based MSM platforms aren't actually using anything in this file just compile io.c on the non-dt based MSM platforms.

Two header files exist in mach-msm's include/mach directory that are only used by the MSM iommu driver. Move these files to the iommu driver directory and prefix them with "msm_".

2013-08-06ARM: msm: Remove devices-iommu.cStephen Boyd
The iommu devices are registered in software, when they should really be part of the DT. Since we don't currently have DT bindings in place for the MSM iommu driver just remove this file for the time being. This is not removing any functionality anyway because these devices aren't probing today due to missing clocks.

I didn't see any acks from the devicetree maintainers, so I've copied them on this pull request. The change itself is minor, and just to the register address.

2013-07-14arm: delete __cpuinit/__CPUINIT usage from all ARM usersPaul Gortmaker
The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the ARM uses of the __cpuinit macros from C code, and all __CPUINIT from assembly code. It also had two ".previous" section statements that were paired off against __CPUINIT (aka .section ".cpuinit.text") that also get removed here.
