2015-03-27ARM: Remove mach-msm and associated ARM architecture codeStephen Boyd1-110/+0
The maintainers for mach-msm no longer have any plans to support or test the platforms supported by this architecture[1]. Most likely there aren't any active users of this code anyway, so let's delete it.

2015-02-28net: smc91x: use run-time configuration on all ARM machinesArnd Bergmann1-1/+7
The smc91x driver traditionally gets configured at compile-time for whichever hardware it runs on. This no longer works on ARM as we continue to move to building all-in-one kernels. Most ARM configurations with this driver already use run-time configuration through DT or through platform_data, but a few have not been converted yet. I've checked all ARM boards that use this driver in their legacy board files, and converted the ones that were using compile-time configuration in smc91x.h to behave like the other ones and provide the interrupt polarity along with the MMIO configuration (width, stride) at platform device creation time. In particular, these combinations were previously selectable in Kconfig but in fact broken: - sa1100 assabet plus pleb - msm combined with any other armv6/v7 platform - pxa-idp combined with any non-DMA pxa variant - LogicPD PXA270 combined with any other pxa - nomadik combined with any other armv4/v5 platform, e.g. versatile. None of these seem critical enough to warrant a backport to stable, but it would be nice to clean this up for good. Signed-off-by: Arnd Bergmann <arnd@arndb.de> ---- I would like the patch to get merged through netdev, after Robert and/or Linus have verified it on at least some hardware. There are a few other non-ARM platforms using this driver, I could do the same patch for those if we want to take it further. arch/arm/mach-msm/board-halibut.c | 8 ++++- arch/arm/mach-msm/board-qsd8x50.c | 8 ++++- arch/arm/mach-pxa/idp.c | 5 +++ arch/arm/mach-pxa/lpd270.c | 8 ++++- arch/arm/mach-realview/core.c | 7 ++++ arch/arm/mach-realview/realview_eb.c | 2 +- arch/arm/mach-sa1100/neponset.c | 6 ++++ arch/arm/mach-sa1100/pleb.c | 7 ++++ drivers/net/ethernet/smsc/smc91x.c | 9 +++-- drivers/net/ethernet/smsc/smc91x.h | 114 ++---------------------------------------------------------- 10 files changed, 57 insertions(+), 117 deletions(-) Tested-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: David S.

2014-06-01ARM: 8025/1: Get rid of meminfoLaura Abbott1-6/+0
memblock is now fully integrated into the kernel and is the prefered method for tracking memory.

2013-08-06ARM: msm: Move mach/board.h contents to common.hStephen Boyd1-1/+0
The contents of mach/board.h are only used by files within mach-msm so there is no need to export this file outside of the mach-msm directory. Move the contents of the file to common.h to allow us to compile MSM in the multi-platform kernel.

2013-06-24ARM: msm: Make proc_comm clock control into a platform driverStephen Boyd1-1/+1
To move closer to the generic struct clock framework move the proc_comm based clock code to a platform driver. The data describing the struct clks still live in the devices-$ARCH file, but the clock initialization is done at driver binding time.

2013-03-05gpio: Make gpio-msm-v1 into a platform driverStephen Boyd1-0/+1
Doing this removes the dependence of this driver on the msm_iomap.h and cpu.h mach include headers provied by MSM. This is necessary to support single zImage work in the future and allows us to remove cpu.h entirely and brings us closer to removing msm_iomap.h.

2012-12-24ARM: delete struct sys_timerStephen Warren1-1/+1
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-09-13ARM: msm: Allow timer.c to compile on multiple targetsStephen Boyd1-3/+2
The timer code relies on #defines from mach/iomap.h, cpu_is_*() checks, and a global irq #define. All this makes this file impossible to compile in a mult-target build. Therefore, make a sys_timer struct for each SoC so that machine descriptors can reference the correct timer. Then go through and replace all the defines with raw values that are passed to a common initialization function. This paves the way to adding DT support to this code as well as allows us to compile this file on multiple targets at the same time.
