dmaengine: mpc512x: Fix module autoload for OF platform driver

2015-10-01T02:04:31+00:00

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

dmaengine: constify of_device_id array

2015-03-18T16:43:14+00:00

of_device_id is always used as const.

dmaengine: Remove FSF mailing addresses

2015-03-16T16:58:15+00:00

Free Software Foundation mailing address has been moved in the past and some
of the addresses here are outdated. Remove them from file headers since the
COPYING file in the kernel sources includes it.

dmaengine: mpc512x: Split device_control

2014-12-22T06:59:04+00:00

Split the device_control callback of the Freescale MPC512x DMA driver to make
use of the newly introduced callbacks, that will eventually be used to retrieve
slave capabilities.

dmaengine: Remove .owner field for driver

2014-11-06T06:24:18+00:00

There is no need to init .owner field.

Based on the patch from Peter Griffin 
"mmc: remove .owner field for drivers using module_platform_driver"

This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

dmaengine: mpc512x: Remove chancnt affectations

2014-11-06T06:02:45+00:00

chanctnt is already filled by dma_async_device_register, which uses the channel
list to know how much channels there is.

Since it's already filled, we can safely remove it from the drivers' probe
function.

dmaengine: mpc512x: register for device tree channel lookup

2014-07-25T18:51:42+00:00

Register the controller for device tree based lookup of DMA channels
(non-fatal for backwards compatibility with older device trees) and
provide the '#dma-cells' property in the shared mpc5121.dtsi file

dmaengine: mpc512x: add support for peripheral transfers

2014-05-22T05:07:01+00:00

Introduce support for slave s/g transfer preparation and the associated
device control callback in the MPC512x DMA controller driver, which adds
support for data transfers between memory and peripheral I/O to the
previously supported mem-to-mem transfers.

dma: mpc512x: fix freeing resources in mpc_dma_probe() and mpc_dma_remove()

2014-05-02T17:06:22+00:00

Fix mpc_dma_probe() error path and mpc_dma_remove(): manually free IRQs and
dispose IRQ mappings before devm_* takes care of other resources.
Moreover replace devm_request_irq() with request_irq() since there is no need
to use it because the original code always frees IRQ manually with
devm_free_irq(). Replace devm_free_irq() with free_irq() accordingly.

dma: mpc512x: separate 'compatible' values for MPC512x and MPC8308

2014-05-02T17:06:21+00:00

MPC512x and MPC8308 have similar DMA controllers, but are independent SoCs.
DMA controller driver should have separate 'compatible' values for these SoCs.
