* Insignal's Exynos4210 based Origen evaluation board
Origen low-cost evaluation board is based on Samsung's Exynos4210 SoC.
Required root node properties:
- compatible = should be one or more of the following.
(a) "samsung,smdkv310" - for Samsung's SMDKV310 eval board.
(b) "samsung,exynos4210" - for boards based on Exynos4210 SoC.
* Samsung's Exynos4210 based SMDKV310 evaluation board
SMDKV310 evaluation board is based on Samsung's Exynos4210 SoC.
Required root node properties:
- compatible = should be one or more of the following.
(a) "samsung,smdkv310" - for Samsung's SMDKV310 eval board.
(b) "samsung,exynos4210" - for boards based on Exynos4210 SoC.
* 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 Exynos4 GPIO Controller
Required properties:
- compatible: Compatible property value should be "samsung,exynos4-gpio>".
- reg: Physical base address of the controller and length of memory mapped
region.
- #gpio-cells: Should be 4. The syntax of the gpio specifier used by client nodes
should be the following with values derived from the SoC user manual.
<[phandle of the gpio controller node]
[pin number within the gpio controller]
[mux function]
[pull up/down]
[drive strength]>
Values for gpio specifier:
- Pin number: is a value between 0 to 7.
- Pull Up/Down: 0 - Pull Up/Down Disabled.
1 - Pull Down Enabled.
3 - Pull Up Enabled.
- Drive Strength: 0 - 1x,
1 - 3x,
2 - 2x,
3 - 4x
- gpio-controller: Specifies that the node is a gpio controller.
- #address-cells: should be 1.
- #size-cells: should be 1.
Example:
gpa0: gpio-controller@11400000 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "samsung,exynos4-gpio";
reg = <0x11400000 0x20>;
#gpio-cells = <4>;
gpio-controller;
};
* 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.
Optional Properties specific to linux:
- linux,keypad-no-autorepeat: do no enable autorepeat feature.
- linux,keypad-wakeup: use any event on keypad as wakeup event.
Example:
keypad@100A0000 {
compatible = "samsung,s5pv210-keypad";
reg = <0x100A0000 0x100>;
interrupts = <173>;
samsung,keypad-num-rows = <2>;
samsung,keypad-num-columns = <8>;
linux,input-no-autorepeat;
linux,input-wakeup;
row-gpios = <&gpx2 0 3 3 0
&gpx2 1 3 3 0>;
col-gpios = <&gpx1 0 3 0 0
&gpx1 1 3 0 0
&gpx1 2 3 0 0
&gpx1 3 3 0 0
&gpx1 4 3 0 0
&gpx1 5 3 0 0
&gpx1 6 3 0 0
&gpx1 7 3 0 0>;
key_1 {
keypad,row = <0>;
keypad,column = <3>;
linux,code = <2>;
};
key_2 {
keypad,row = <0>;
keypad,column = <4>;
linux,code = <3>;
};
key_3 {
keypad,row = <0>;
keypad,column = <5>;
linux,code = <4>;
};
};
* Samsung's S3C Real Time Clock controller
Required properties:
- compatible: should be one of the following.
* "samsung,s3c2410-rtc" - for controllers compatible with s3c2410 rtc.
* "samsung,s3c6410-rtc" - for controllers compatible with s3c6410 rtc.
- reg: physical base address of the controller and length of memory mapped
region.
- interrupts: Two interrupt numbers to the cpu should be specified. First
interrupt number is the rtc alarm interupt and second interrupt number
is the rtc tick interrupt. The number of cells representing a interrupt
depends on the parent interrupt controller.
Example:
rtc@10070000 {
compatible = "samsung,s3c6410-rtc";
reg = <0x10070000 0x100>;
interrupts = <44 0 45 0>;
};
* Samsung's UART Controller
The Samsung's UART controller is used for interfacing SoC with serial communicaion
devices.
Required properties:
- compatible: should be
- "samsung,exynos4210-uart", for UART's compatible with Exynos4210 uart ports.
- reg: base physical address of the controller and length of memory mapped
region.
- interrupts: interrupt number to the cpu. The interrupt specifier format depends
on the interrupt controller parent.
