Merge branch 'platforms' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM platform updates from Russell King: "This covers platform stuff for platforms I have a direct interest in (iow, I have the hardware). Essentially: - as we no longer support any other Acorn platforms other than RiscPC anymore, we can collect all that code into mach-rpc. - convert Acorn expansion card stuff to use IRQ allocation functions, and get rid of NO_IRQ from there. - cleanups to the ebsa110 platform to move some private stuff out of its header files. - large amount of SA11x0 updates: - conversion of private DMA implementation to DMA engine support (this actually gives us greater flexibility in drivers over the old API.) - re-worked ucb1x00 updates - convert to genirq, remove sa11x0 dependencies, fix various minor issues - move platform specific sa11x0 framebuffer data into platform files in arch/arm instead of keeping this in the driver itself - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA for SIR transmissions as well as FIR - rework sa1111 support for genirq, and irq allocation - fix sa1111 IRQ support so it works again - use sparse IRQ support After this, I have one more pull request remaining from my current set, which I think is going to be the most problematical as it generates 8 conflicts." Fixed up the trivial conflict in arch/arm/mach-rpc/Makefile as per Russell. * 'platforms' of git://git.linaro.org/people/rmk/linux-arm: (125 commits) ARM: 7343/1: sa11x0: convert to sparse IRQ ARM: 7342/2: sa1100: prepare for sparse irq conversion ARM: 7341/1: input: prepare jornada720 keyboard and ts for sa11x0 sparse irq ARM: 7340/1: rtc: sa1100: include mach/irqs.h instead of asm/irq.h ARM: sa11x0: remove unused DMA controller definitions ARM: sa11x0: remove old SoC private DMA driver USB: sa1111: add hcd .reset method USB: sa1111: add OHCI shutdown methods USB: sa1111: reorganize ohci-sa1111.c USB: sa1111: get rid of nasty printk(KERN_DEBUG "%s: ...", __FILE__) USB: sa1111: sparse and checkpatch cleanups ARM: sa11x0: don't static map sa1111 ARM: sa1111: use dev_err() rather than printk() ARM: sa1111: cleanup sub-device registration and unregistration ARM: sa1111: only setup DMA for DMA capable devices ARM: sa1111: register sa1111 devices with dmabounce in bus notifier ARM: sa1111: move USB interface register definitions to ohci-sa1111.c ARM: sa1111: move PCMCIA interface register definitions to sa1111_generic.c ARM: sa1111: move PS/2 interface register definitions to sa1111p2.c ARM: sa1111: delete unused physical GPIO register definitions ...
