dma: lpc32xx: add DMA driver

2015-08-18T17:45:55+00:00

Incorporate DMA driver from legacy LPCLinux NXP BSP.
The files taken from the legacy patch are:
- lpc32xx DMA driver
- lpc3250 header file DMA registers definition.

The legacy driver was updated and clean-up as part of the integration with the latest u-boot.

dma: keystone_nav: remove spurious qm_cfg verification

2014-11-06T16:04:39+00:00

The verification qm_cfg existence is done at ksnav_init().
So, there is no need to verify it after initialization.

dma: ti-edma3: introduce edma3 driver

2014-10-23T15:27:29+00:00

The EDMA3 controller’s primary purpose is to service data transfers
that you program between two memory-mapped slave endpoints on the device.

Typical usage includes, but is not limited to the following:
- Servicing software-driven paging transfers (e.g., transfers from external
  memory, such as SDRAM to internal device memory, such as DSP L2 SRAM)
- Servicing event-driven peripherals, such as a serial port
- Performing sorting or sub-frame extraction of various data structures
- Offloading data transfers from the main device DSP(s)
- See the device-specific data manual for specific peripherals that are
  accessible via the EDMA3 controller

dma: keystone_nav: generalize driver usage

2014-10-23T15:27:04+00:00

The keystone_nav driver is general driver intended to be used for
working with queue manager and pktdma for different IPs like NETCP,
AIF, FFTC, etc. So the it's API shouldn't be named like it works only
with one of them, it should be general names. The names with prefix
like netcp_* rather do for drivers/net/keystone_net.c driver. So it's
good to generalize this driver to be used for different IP's and
delete confusion with real NETCP driver.

The current netcp_* functions of keystone navigator can be used for
other settings of pktdma, not only for NETCP. The API of this driver
is used by the keystone_net driver to work with NETCP, so net driver
also should be corrected. For convenience collect pkdma
configurations in drivers/dma/keystone_nav_cfg.c.

dma: keystone_nav: move keystone_nav driver to driver/dma/

2014-10-23T15:27:04+00:00

The keystone_nav is used by drivers/net/keystone_net.c driver to
send and receive packets, but currently it's placed at keystone
arch sources. So it should be in the drivers directory also.
It's separate driver that can be used for sending and receiving
pktdma packets by others drivers also.

This patch just move this driver to appropriate directory and
doesn't add any functional changes.
