* i.MX31: framebuffer driverGuennadi Liakhovetski2009-01-211-0/+38
| | | | | | | | | This is a framebuffer driver for i.MX31 SoCs. It only supports synchronous displays, vertical panning supported, no overlay support.

* i.MX31: Image Processing Unit DMA and IRQ driversGuennadi Liakhovetski2009-01-192-1/+190
| | | | | | | | | | | | | | | | | | | | | | i.MX3x SoCs contain an Image Processing Unit, consisting of a Control Module (CM), Display Interface (DI), Synchronous Display Controller (SDC), Asynchronous Display Controller (ADC), Image Converter (IC), Post-Filter (PF), Camera Sensor Interface (CSI), and an Image DMA Controller (IDMAC). CM contains, among other blocks, an Interrupt Generator (IG) and a Clock and Reset Control Unit (CRCU). This driver serves IDMAC and IG. They are supported over dmaengine and irq-chip APIs respectively. IDMAC is a specialised DMA controller, its DMA channels cannot be used for general-purpose operations, even though it might be possible to configure a memory-to-memory channel for memcpy operation. This driver will not work with generic dmaengine clients, clients, wishing to use it must use respective wrapper structures, they also must specify which channels they require, as channels are hard-wired to specific IPU functions.

| * cpumask: convert struct clock_event_device to cpumask pointers.Rusty Russell2008-12-131-1/+1

* | [ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King2008-11-293-16/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.
