2012-03-26ARM: tegra: Include assembler.h in sleep.S to fix build breakStephen Warren1-1/+3
Commit 6f6f6a7 "ARM: create a common IOMEM definition" moved macro IOMEM(), and requires users to include <asm/assembler.h>. Fix Tegra's sleep.S to do so. This fixes: arch/arm/mach-tegra/sleep.S: Assembler messages: arch/arm/mach-tegra/sleep.S:77: Error: missing ')' arch/arm/mach-tegra/sleep.S:77: Error: garbage following instruction -- `movw r0,#:lower16:(0x60007000-0x60000000+IOMEM(0xFE200000))' Note: This only shows up after 0a25893 "ARM: tegra: update defconfig" Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

2012-03-25ARM: pxa: use common IOMEM definitionRob Herring9-2/+8
pxa was missed in the moving of IOMEM to a common definition, so lots of IOMEM redefined warnings were introduced. So remove pxa IOMEM definition and fix all the fallout.

2012-03-25ARM: dma-mapping: convert ARCH_HAS_DMA_SET_COHERENT_MASK to kconfig symbolRob Herring4-6/+5
The only users of ARCH_HAS_DMA_SET_COHERENT_MASK are 2 ARM platforms: ixp4xx and pxa cm_x2xx. We've been getting lucky that the define is implicitly included before dma-mapping.h, but the removal of io.h broke things (c334bc1 ARM: make mach/io.h include optional). Since memory.h is the correct place, but no longer exists, convert the define to a kconfig entry.

2012-03-18arm/tegra: pcie: fix return value of functionDmitry Artamonow1-3/+3
In previous patch (arm/tegra: add timeout to PCIe PLL lock detection loop) tegra_pcie_enable_controller() function type has been changed from void to int, but the last return statement wasn't converted, so function returns undefined value. Fix it. Also while at it, address couple of minor concerns raised by reviewers: use usleep_range for delay, and lower the value of timeout to 300ms to be consistent with Nvidia Vibrante kernel.

2012-03-14ARM: create a common IOMEM definitionRob Herring25-88/+13
Several platforms create IOMEM defines for casting to 'void __iomem *', and other platforms are incorrectly using __io() macro for the same purpose. This creates a common definition and removes all the platform specific versions. Rather than try to make linux/io.h and asm/io.h assembly safe, the assembly version of IOMEM is moved into asm/assembler.h.

2012-03-12ARM: fix ioremap/iounmap for !CONFIG_MMURob Herring1-2/+6
With commit 4fe7ef3a081 (ARM: provide runtime hook for ioremap/iounmap), compiles with !CONFIG_MMU were broken. Rename nommu __iounmap to __arm_iounmap and add arch_ioremap_caller and arch_iounmap.

2012-03-08arm/tegra: add timeout to PCIe PLL lock detection loopDmitry Artamonow1-3/+11
Tegra PCIe driver waits for PLL to lock using busy loop. If PLL fails to lock for some reason, this leads to silent lockup while booting (as PCIe code is not modular). Fix by adding timeout, so if PLL doesn't lock in a couple of seconds, just PCIe driver fails and machine continues to boot.

2012-03-07ARM: provide runtime hook for ioremap/iounmapRob Herring2-4/+20
We have compile time over-ride of ioremap and iounmap, but an run-time override is needed for multi-platform builds. This adds an extra function pointer check, but ioremap is not peformance critical. The option for compile time selection remains. The caller variant is used here to provide correct caller information as ARM can only support level 0 for __builtin_return_address.
