DMAengine updates for v4.19-rc1
This round brings couple of framework changes, a new driver and usual driver
updates:
- New managed helper for dmaengine framework registration
- Split dmaengine pause capability to pause and resume and allow drivers to
report that individually
- Update dma_request_chan_by_mask() to handle deferred probing
- Move imx-sdma to use virt-dma
- New driver for Actions Semi Owl family S900 controller
- Minor updates to intel, renesas, mv_xor, pl330 etc

* Actions Semi Owl SoCs DMA controller
|
||||
|
||||
This binding follows the generic DMA bindings defined in dma.txt.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be "actions,s900-dma".
|
||||
- reg: Should contain DMA registers location and length.
|
||||
- interrupts: Should contain 4 interrupts shared by all channel.
|
||||
- #dma-cells: Must be <1>. Used to represent the number of integer
|
||||
cells in the dmas property of client device.
|
||||
- dma-channels: Physical channels supported.
|
||||
- dma-requests: Number of DMA request signals supported by the controller.
|
||||
Refer to Documentation/devicetree/bindings/dma/dma.txt
|
||||
- clocks: Phandle and Specifier of the clock feeding the DMA controller.
|
||||
|
||||
Example:
|
||||
|
||||
Controller:
|
||||
dma: dma-controller@e0260000 {
|
||||
compatible = "actions,s900-dma";
|
||||
reg = <0x0 0xe0260000 0x0 0x1000>;
|
||||
interrupts = <GIC_SPI 57 IRQ_TYPE_LEVEL_HIGH>,
|
||||
<GIC_SPI 58 IRQ_TYPE_LEVEL_HIGH>,
|
||||
<GIC_SPI 59 IRQ_TYPE_LEVEL_HIGH>,
|
||||
<GIC_SPI 60 IRQ_TYPE_LEVEL_HIGH>;
|
||||
#dma-cells = <1>;
|
||||
dma-channels = <12>;
|
||||
dma-requests = <46>;
|
||||
clocks = <&clock CLK_DMAC>;
|
||||
};
|
||||
|
||||
Client:
|
||||
|
||||
DMA clients connected to the Actions Semi Owl SoCs DMA controller must
|
||||
use the format described in the dma.txt file, using a two-cell specifier
|
||||
for each channel.
|
||||
|
||||
The two cells in order are:
|
||||
1. A phandle pointing to the DMA controller.
|
||||
2. The channel id.
