* ARM PrimeCell PL330 DMA Controller
|
||||||
|
|
||||||
|
The ARM PrimeCell PL330 DMA controller can move blocks of memory contents
|
||||||
|
between memory and peripherals or memory to memory.
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible: should include both "arm,pl330" and "arm,primecell".
|
||||||
|
- reg: physical base address of the controller and length of memory mapped
|
||||||
|
region.
|
||||||
|
- interrupts: interrupt number to the cpu.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
pdma0: pdma@12680000 {
|
||||||
|
compatible = "arm,pl330", "arm,primecell";
|
||||||
|
reg = <0x12680000 0x1000>;
|
||||||
|
interrupts = <99>;
|
||||||
|
};
|
||||||
|
|
||||||
|
Client drivers (device nodes requiring dma transfers from dev-to-mem or
|
||||||
|
mem-to-dev) should specify the DMA channel numbers using a two-value pair
|
||||||
|
as shown below.
|
||||||
|
|
||||||
|
[property name] = <[phandle of the dma controller] [dma request id]>;
|
||||||
|
|
||||||
|
where 'dma request id' is the dma request number which is connected
|
||||||
|
to the client controller. The 'property name' is recommended to be
|
||||||
|
of the form <name>-dma-channel.
|
||||||
|
|
||||||
|
Example: tx-dma-channel = <&pdma0 12>;

* Samsung's Keypad Controller device tree bindings
|
||||||
|
|
||||||
|
Samsung's Keypad controller is used to interface a SoC with a matrix-type
|
||||||
|
keypad device. The keypad controller supports multiple row and column lines.
|
||||||
|
A key can be placed at each intersection of a unique row and a unique column.
|
||||||
|
The keypad controller can sense a key-press and key-release and report the
|
||||||
|
event using a interrupt to the cpu.
|
||||||
|
|
||||||
|
Required SoC Specific Properties:
|
||||||
|
- compatible: should be one of the following
|
||||||
|
- "samsung,s3c6410-keypad": For controllers compatible with s3c6410 keypad
|
||||||
|
controller.
|
||||||
|
- "samsung,s5pv210-keypad": For controllers compatible with s5pv210 keypad
|
||||||
|
controller.
|
||||||
|
|
||||||
|
- reg: physical base address of the controller and length of memory mapped
|
||||||
|
region.
|
||||||
|
|
||||||
|
- interrupts: The interrupt number to the cpu.
|
||||||
|
|
||||||
|
Required Board Specific Properties:
|
||||||
|
- samsung,keypad-num-rows: Number of row lines connected to the keypad
|
||||||
|
controller.
|
||||||
|
|
||||||
|
- samsung,keypad-num-columns: Number of column lines connected to the
|
||||||
|
keypad controller.
|
||||||
|
|
||||||
|
- row-gpios: List of gpios used as row lines. The gpio specifier for
|
||||||
|
this property depends on the gpio controller to which these row lines
|
||||||
|
are connected.
|
||||||
|
|
||||||
|
- col-gpios: List of gpios used as column lines. The gpio specifier for
|
||||||
|
this property depends on the gpio controller to which these column
|
||||||
|
lines are connected.
|
||||||
|
|
||||||
|
- Keys represented as child nodes: Each key connected to the keypad
|
||||||
|
controller is represented as a child node to the keypad controller
|
||||||
|
device node and should include the following properties.
|
||||||
|
- keypad,row: the row number to which the key is connected.
|
||||||
|
- keypad,column: the column number to which the key is connected.
|
||||||
|
- linux,code: the key-code to be reported when the key is pressed
|
||||||
|
and released.
