This allow peripheral to memory and memory to peripheral transfers with hardware handshaking. Slave structure for controller specific information is passed through channel private data. This at_dma_slave structure is defined in at_hdmac.h header file and relative hardware definition are moved to this file from at_hdmac_regs.h. Doing this we allow the channel configuration from platform definition code. This work is intensively based on dw_dmac and several slave implementations.

On other products, it will be used also for peripheral DMA transfer (slave API support to come). I used dmatest client without problem in different configurations to test it.

However, other parts of the dmaengine infrastructure do not suffer this constraint, so the HIGHMEM64G restriction can be down-levelled. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

The bit in the mode register that controls external pause on the 85xx controller happens to be part of the bandwidth control settings for the 83xx controller. This patch fixes the driver so that it only clears the external pause bit if the hardware is the 85xx controller. When driving the 83xx controller, the bit is left untouched. This follows the existing convention that mode registers settings are not touched unless necessary. Signed-off-by: Ira W.

Setting the controller to use the PCI Read Multiple command instead allows the controller to read much larger bursts of data, which provides a drastic speed increase. The slowdown due to using PCI Read Line was only observed when a PCI-to-PCI bridge was between the devices trying to communicate. A simple test driver showed an increase from 4MB/sec to 116MB/sec when performing DMA over the PCI bus. Using DMA to transfer between blocks of local SDRAM showed no change in performance with this patch. The dmatest driver was also used to verify the correctness of the transfers, and showed no errors.

Otherwise some data bytes can be lost while transferring them from the memory to the I2C interface. Do a Busy-wait for XUDF, before writing data to DATA_REG. While waiting if there is NACK | AL, set the appropriate error flags, ack the pending interrupts and return from the ISR.

This change makes the driver register a bit earlier which together with earlier platform data moves the time for probe(). The earlier probe() makes it possible to use i2c_get_adapter() and i2c_transfer() from device_initcall(). The same strategy is used by other i2c bus drivers such as i2c-pxa.c and i2c-s3c2410.c.
