1 | * ARM PrimeCell PL330 DMA Controller | ||
2 | |||
3 | The ARM PrimeCell PL330 DMA controller can move blocks of memory contents | ||

8 | - reg: physical base address of the controller and length of memory mapped | ||
9 | region. | ||
10 | - interrupts: interrupt number to the cpu. | ||

20 | Client drivers (device nodes requiring dma transfers from dev-to-mem or | ||

23 | |||
24 | [property name] = <[phandle of the dma controller] [dma request id]>; | ||
25 | |||
26 | where 'dma request id' is the dma request number which is connected | ||
27 | to the client controller. The 'property name' is recommended to be | ||
28 | of the form <name>-dma-channel. | ||
29 | |||

1 | * Samsung's Keypad Controller device tree bindings | ||
2 | |||
3 | Samsung's Keypad controller is used to interface a SoC with a matrix-type | ||
4 | keypad device. The keypad controller supports multiple row and column lines. | ||
5 | A key can be placed at each intersection of a unique row and a unique column. | ||
6 | The keypad controller can sense a key-press and key-release and report the | ||
7 | event using a interrupt to the cpu. | ||
8 | |||
9 | Required SoC Specific Properties: | ||
10 | - compatible: should be one of the following | ||
11 | - "samsung,s3c6410-keypad": For controllers compatible with s3c6410 keypad | ||
12 | controller. | ||
13 | - "samsung,s5pv210-keypad": For controllers compatible with s5pv210 keypad | ||
14 | controller. | ||
15 | |||
16 | - reg: physical base address of the controller and length of memory mapped | ||
17 | region. | ||
18 | |||
19 | - interrupts: The interrupt number to the cpu. | ||
20 | |||
21 | Required Board Specific Properties: | ||
22 | - samsung,keypad-num-rows: Number of row lines connected to the keypad | ||
23 | controller. | ||
24 | |||
25 | - samsung,keypad-num-columns: Number of column lines connected to the | ||
26 | keypad controller. | ||
27 | |||
28 | - row-gpios: List of gpios used as row lines. The gpio specifier for | ||
29 | this property depends on the gpio controller to which these row lines | ||
30 | are connected. | ||
31 | |||
32 | - col-gpios: List of gpios used as column lines. The gpio specifier for | ||
33 | this property depends on the gpio controller to which these column | ||
34 | lines are connected. | ||
35 | |||
36 | - Keys represented as child nodes: Each key connected to the keypad | ||
37 | controller is represented as a child node to the keypad controller | ||
38 | device node and should include the following properties. | ||
39 | - keypad,row: the row number to which the key is connected. | ||
40 | - keypad,column: the column number to which the key is connected. | ||
41 | - linux,code: the key-code to be reported when the key is pressed | ||
42 | and released. | ||
43 | |||
44 | Optional Properties specific to linux: | ||
45 | - linux,keypad-no-autorepeat: do no enable autorepeat feature. | ||
