Remove the new unused DMA controller definitions from mach/SA-1100.h. These are now private to the SA-11x0 DMA engine driver and contained within the driver. Signed-off-by:

Combine usb_hcd_sa1111_probe() and ohci_hcd_sa1111_drv_probe(), doing the same for the remove methods. Move sa1111_start_hc and sa1111_stop_hc to be located next to these the probe/release functions, as they're only called from them. Get rid of the /*----*/ breaker lines. Acked-by:

Clean up the ohci-sa1111 driver formatting to be more compliant with current standards, and add 'static' to various function definitions to avoid sparse complaints about undeclared functions. Remove the unnecessary local declaration of 'usb_disabled', which can be found instead in linux/usb.h. Acked-by:

The sa1111 support will ioremap() the device; there is no need for platforms to setup a static mapping for this. Remove the static mapping for this device from badge4, jornada720 and neponset. Acked-by:

It's pointless registering the PS/2 interfaces with the dmabounce code when there's no DMA support for these in hardware, so only setup the DMA masks for two subdevices which support DMA - the OHCI and SAC. Acked-by:

As the DMA engine API allows DMA channels to be reconfigured on the fly, we can now support switching the DMA channel configuration to support SIR transmit DMA without needing to claim an additional physical DMA channel - thereby using up half the DMA channels just for one driver. Signed-off-by:

Add support for the SA-11x0 DMA driver, which replaces the private API version in arch/arm/mach-sa1100/dma.c. We model this as a set of virtual DMA channels, one for each request signal, and assign the virtual DMA channel to a physical DMA channel when there is work to be done. This allows DMA users to claim their channels, and hold them while not in use, without affecting the availability of the physical channels. Another advantage over this approach, compared to the private version, is that a channel can be reconfigured on the fly without having to release and re-request it - which for the IrDA driver, allows us to use DMA for SIR mode transmit without eating up three physical channels. As IrDA is half-duplex, we actually only need one physical channel, and this architecture allows us to achieve that. Signed-off-by:

The sa1100fb driver needs to set the GPIO direction and alternate function register according to the panel that we're driving. We've done this in the driver by read-modify-writing the register, which may cause problems with races. Fix this with a minimal change. Acked-by:
