2016-03-04usb: gadget: pxa25x_udc: move register definitions from archArnd Bergmann1-198/+0
ixp4xx and pxa25x both use this driver and provide a slightly different set of register definitions for it. Aside from that, the definition in the ixp4xx-regs.h header conflicts with the on in the pxa27x device driver when compile-testing that: In file included from ../drivers/usb/gadget/udc/pxa27x_udc.c:37:0: ../drivers/usb/gadget/udc/pxa27x_udc.h:26:0: warning: "UDCCR" redefined #define UDCCR 0x0000 /* UDC Control Register */ ^ In file included from ../arch/arm/mach-ixp4xx/include/mach/hardware.h:27:0, from ../arch/arm/mach-ixp4xx/include/mach/io.h:18, from ../arch/arm/include/asm/io.h:194, from ../include/linux/io.h:25, from ../include/linux/irq.h:24, from ../drivers/usb/gadget/udc/pxa27x_udc.c:23: ../arch/arm/mach-ixp4xx/include/mach/ixp4xx-regs.h:415:0: note: this is the location of the previous definition #define UDCCR IXP4XX_USB_REG(IXP4XX_USB_BASE_VIRT+0x0000) This addresses both issues by moving all the definitions into the pxa25x_udc driver itself. It turns out the only difference between them was 'UDCCS_IO_ROF', and that could well be a mistake when it was incorrectly copied from pxa25x to ixp4xx.

2015-12-02ARM: ixp4xx: fix read{b,w,l} return typesArnd Bergmann1-6/+6
On ixp4xx, the readl() function returns an 'unsigned long' output when indirect I/O is used. This is unlike any other platform, and it causes lots of harmless compiler warnings, such as: drivers/ata/libahci.c: In function 'ahci_show_host_version': drivers/ata/libahci.c:254:22: warning: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int' [-Wformat=] drivers/block/mtip32xx/mtip32xx.c: In function 'mtip_hw_read_registers': drivers/block/mtip32xx/mtip32xx.c:2602:31: warning: format '%X' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int' [-Wformat=] drivers/block/cciss.c: In function 'print_cfg_table': drivers/block/cciss.c:3845:25: warning: format '%d' expects argument of type 'int', but argument 4 has type 'long unsigned int' [-Wformat=] This changes all six of the ixp4xx specific I/O read functions to return the same types that we have in the normal asm/io.h, to avoid the warnings.

2012-11-22IXP4xx: use __iomem for MMIOArnd Bergmann1-6/+6

We have architectured timer support here, which is a set of timers specified by the ARM architecture for future SoCs. So we should see less variability in timer design going forward. The last big thing here is my cleanup to the way we handle PCI across ARM, fixing some oddities in some platforms which hadn't realised there was a way to deal with their private data already built in to our PCI backend. I've also removed support for the ARMv3 architecture; it hasn't worked properly for years so it seems pointless to keep it around." * 'for-linus' of git://git.linaro.org/people/rmk/linux-arm: (47 commits) ARM: PCI: remove per-pci_hw list of buses ARM: PCI: dove/kirkwood/mv78xx0: use sys->private_data ARM: PCI: provide a default bus scan implementation ARM: PCI: get rid of pci_std_swizzle() ARM: PCI: versatile: fix PCI interrupt setup ARM: PCI: integrator: use common PCI swizzle ARM: 7416/1: LPAE: Remove unused L_PTE_(BUFFERABLE|CACHEABLE) macros ARM: 7415/1: vfp: convert printk's to pr_*'s ARM: decompressor: avoid speculative prefetch from non-RAM areas ARM: Remove ARMv3 support from decompressor ARM: 7413/1: move read_{boot,persistent}_clock to the architecture level ARM: Remove support for ARMv3 ARM610 and ARM710 CPUs ARM: 7363/1: DEBUG_LL: limit early mapping to the minimum ARM: 7391/1: versatile: add some auxdata for device trees ARM: 7389/2: plat-versatile: modernize FPGA IRQ controller AMBA: get rid of last two uses of NO_IRQ ARM: 7408/1: cacheflush: return error to userspace when flushing syscall fails ARM: 7409/1: Do not call flush_cache_user_range with mmap_sem held ARM: 7404/1: cmpxchg64: use atomic64 and local64 routines for cmpxchg64 ARM: 7347/1: SCU: use cpu_logical_map for per-CPU low power mode ...
2012-05-13ARM: PCI: provide a default bus scan implementationRussell King1-1/+1
Most PCI implementations perform simple root bus scanning. Rather than having each group of platforms provide a duplicated bus scan function, provide the PCI configuration ops structure via the hw_pci structure, and call the root bus scanning function from core ARM PCI code.

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.

Remove the now empty arch_reset() from all the mach/system.h includes, and remove its callsite. Remove arm_machine_restart() as this function no longer does anything useful. For samsung platforms, remove the include of mach/system-reset.h and plat/system-reset.h from their respective mach/system.h headers as these just define their arch_reset functions. As a result, the s3c2410 and plat-samsung system-reset.h files are no longer referenced, so remove these files entirely.

2011-11-21ARM: restart: only perform setup for restart when soft-restartingRussell King1-1/+1
We only need to set the system up for a soft-restart if we're going to be doing a soft-restart. Provide a new function (soft_restart()) which does the setup and final call for this, and make platforms use it. Eliminate the call to setup_restart() from the default handler. This means that platforms arch_reset() function is no longer called with the page tables prepared for a soft-restart, and caches will still be enabled.
