i.MX31: Image Processing Unit DMA and IRQ drivers
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.

This enables the use of DMA engines in the network stack to

offload receive copy-to-user operations, freeing CPU cycles.

Say Y here if you enabled INTEL_IOATDMA or FSL_DMA, otherwise
|
|
|
|

say N.

This allows the async_tx api to take advantage of offload engines for
|
|
|
|
|
memcpy, memset, xor, and raid6 p+q operations. If your platform has
|
|
|
|
|
a dma engine that can perform raid operations and you have enabled
|
|
|
|
|
MD_RAID456 say Y.
|
|
|
|

|
|

|
|
If unsure, say N.
