-Samsung S3C24XX GPIO Controller
-
-Required properties:
-- compatible: Compatible property value should be "samsung,s3c24xx-gpio".
-
-- reg: Physical base address of the controller and length of memory mapped
- region.
-
-- #gpio-cells: Should be 3. 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]
- [flags and pull up/down]
-
- Values for gpio specifier:
- - Pin number: depending on the controller a number from 0 up to 15.
- - Mux function: Depending on the SoC and the gpio bank the gpio can be set
- as input, output or a special function
- - Flags and Pull Up/Down: the values to use differ for the individual SoCs
- example S3C2416/S3C2450:
- 0 - Pull Up/Down Disabled.
- 1 - Pull Down Enabled.
- 2 - Pull Up Enabled.
- Bit 16 (0x00010000) - Input is active low.
- Consult the user manual for the correct values of Mux and Pull Up/Down.
-
-- gpio-controller: Specifies that the node is a gpio controller.
-- #address-cells: should be 1.
-- #size-cells: should be 1.

-Example:
-
- gpa: gpio-controller@56000000 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "samsung,s3c24xx-gpio";
- reg = <0x56000000 0x10>;
