dmaengine: ti: Add missing put_device in ti_dra7_xbar_route_allocate

2022-06-09T06:00:31+00:00

of_find_device_by_node() takes reference, we should use put_device()
to release it when not need anymore.

dmaengine: ti: Fix refcount leak in ti_dra7_xbar_route_allocate

2022-06-09T06:00:30+00:00

of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not needed anymore.

Add missing of_node_put() in to fix this.

2022-05-19T17:28:02+00:00

The generic property, used in most of the drivers and defined in generic
dma-common DT bindings, is 'dma-channels'.  Switch to new property while
keeping backward compatibility.

dma: omap: hide legacy interface

2022-04-22T09:08:43+00:00

The legacy interface for omap-dma is only used on OMAP1, and the
same is true for the non-DT case. Make both of these conditional on
CONFIG_ARCH_OMAP1 being set to simplify the dependency.

The non-OMAP stub functions in include/linux/omap-dma.h are note needed
any more either now, because they are only called on OMAP1.
