Merge tag 'ux500-dma40-for-arm-soc' of... 

Merge tag 'ux500-dma40-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/drivers

From Linus Walleij:
This is a set of patches from Lee Jones to start converting
the ux500 to fetch DMA channels from the device tree:
- Full DT support and channel mapping in the DMA40 driver
- Dropping of platform data for migrated devices on the DT
  boot path.

* tag 'ux500-dma40-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson

* DMA40 DMA Controller



Required properties:

- compatible: "stericsson,dma40"

- reg: Address range of the DMAC registers

- reg-names: Names of the above areas to use during resource look-up

- interrupt: Should contain the DMAC interrupt number

- #dma-cells: must be <3>



Optional properties:

- dma-channels: Number of channels supported by hardware - if not present

		the driver will attempt to obtain the information from H/W



Example:



	dma: dma-controller@801C0000 {

		compatible = "stericsson,db8500-dma40", "stericsson,dma40";

		reg = <0x801C0000 0x1000  0x40010000 0x800>;

		reg-names = "base", "lcpa";

		interrupt-parent = <&intc>;

		interrupts = <0 25 0x4>;



		#dma-cells = <2>;

		dma-channels = <8>;

	};



Clients

Required properties:

- dmas: Comma separated list of dma channel requests

- dma-names: Names of the aforementioned requested channels



Each dmas request consists of 4 cells:

  1. A phandle pointing to the DMA controller

  2. Device Type

  3. The DMA request line number (only when 'use fixed channel' is set)

  4. A 32bit mask specifying; mode, direction and endianess [NB: This list will grow]

        0x00000001: Mode:

                Logical channel when unset

                Physical channel when set

        0x00000002: Direction:

                Memory to Device when unset

                Device to Memory when set

        0x00000004: Endianess:

                Little endian when unset

                Big endian when set

        0x00000008: Use fixed channel:

                Use automatic channel selection when unset

                Use DMA request line number when set



Example:



	uart@80120000 {

		compatible = "arm,pl011", "arm,primecell";

		reg = <0x80120000 0x1000>;

		interrupts = <0 11 0x4>;



		dmas = <&dma 13 0 0x2>, /* Logical - DevToMem */

		       <&dma 13 0 0x0>; /* Logical - MemToDev */

		dma-names = "rx", "rx";



		status = "disabled";
