Davinci/Keystone GPIO controller bindings
|
|
||||||
|
|
||||||
Required Properties:
|
|
||||||
- compatible: should be "ti,dm6441-gpio": for Davinci da850 SoCs
|
|
||||||
"ti,keystone-gpio": for Keystone 2 66AK2H/K, 66AK2L,
|
|
||||||
66AK2E SoCs
|
|
||||||
"ti,k2g-gpio", "ti,keystone-gpio": for 66AK2G
|
|
||||||
"ti,am654-gpio", "ti,keystone-gpio": for TI K3 AM654
|
|
||||||
"ti,j721e-gpio", "ti,keystone-gpio": for J721E SoCs
|
|
||||||
"ti,am64-gpio", "ti,keystone-gpio": for AM64 SoCs
|
|
||||||
|
|
||||||
- reg: Physical base address of the controller and the size of memory mapped
|
|
||||||
registers.
|
|
||||||
|
|
||||||
- gpio-controller : Marks the device node as a gpio controller.
|
|
||||||
|
|
||||||
- #gpio-cells : Should be two.
|
|
||||||
- first cell is the pin number
|
|
||||||
- second cell is used to specify optional parameters (unused)
|
|
||||||
|
|
||||||
- interrupts: Array of GPIO interrupt number. Only banked or unbanked IRQs are
|
|
||||||
supported at a time.
|
|
||||||
|
|
||||||
- ti,ngpio: The number of GPIO pins supported.
|
|
||||||
|
|
||||||
- ti,davinci-gpio-unbanked: The number of GPIOs that have an individual interrupt
|
|
||||||
line to processor.
|
|
||||||
|
|
||||||
- clocks: Should contain the device's input clock, and should be defined as per
|
|
||||||
the appropriate clock bindings consumer usage in,
|
|
||||||
|
|
||||||
Documentation/devicetree/bindings/clock/keystone-gate.txt
|
|
||||||
for 66AK2HK/66AK2L/66AK2E SoCs or,
|
|
||||||
|
|
||||||
Documentation/devicetree/bindings/clock/ti,sci-clk.txt
|
|
||||||
for 66AK2G SoCs
|
|
||||||
|
|
||||||
- clock-names: Name should be "gpio";
|
|
||||||
|
|
||||||
Currently clock-names and clocks are needed for all keystone 2 platforms
|
|
||||||
Davinci platforms do not have DT clocks as of now.
|
|
||||||
|
|
||||||
The GPIO controller also acts as an interrupt controller. It uses the default
|
|
||||||
two cells specifier as described in Documentation/devicetree/bindings/
|
|
||||||
interrupt-controller/interrupts.txt.
|
|
||||||
|
|
||||||
Example:
|
|
||||||
|
|
||||||
gpio: gpio@1e26000 {
|
|
||||||
compatible = "ti,dm6441-gpio";
|
|
||||||
gpio-controller;
|
|
||||||
#gpio-cells = <2>;
|
|
||||||
reg = <0x226000 0x1000>;
|
|
||||||
interrupt-parent = <&intc>;
|
|
||||||
interrupts = <42 IRQ_TYPE_EDGE_BOTH 43 IRQ_TYPE_EDGE_BOTH
|
|
||||||
44 IRQ_TYPE_EDGE_BOTH 45 IRQ_TYPE_EDGE_BOTH
|
|
||||||
46 IRQ_TYPE_EDGE_BOTH 47 IRQ_TYPE_EDGE_BOTH
|
|
||||||
48 IRQ_TYPE_EDGE_BOTH 49 IRQ_TYPE_EDGE_BOTH
|
|
||||||
50 IRQ_TYPE_EDGE_BOTH>;
|
|
||||||
ti,ngpio = <144>;
|
|
||||||
ti,davinci-gpio-unbanked = <0>;
|
|
||||||
interrupt-controller;
|
|
||||||
#interrupt-cells = <2>;
|
|
||||||
};
|
|
||||||
|
|
||||||
leds {
|
|
||||||
compatible = "gpio-leds";
|
|
||||||
|
|
||||||
led1 {
|
|
||||||
label = "davinci:green:usr1";
|
|
||||||
gpios = <&gpio 10 GPIO_ACTIVE_HIGH>;
|
|
||||||
...
|
|
||||||
};
|
|
||||||
|
|
||||||
led2 {
|
|
||||||
label = "davinci:red:debug1";
|
|
||||||
gpios = <&gpio 11 GPIO_ACTIVE_HIGH>;
|
|
||||||
...
|
|
||||||
};
|
|
||||||
};
|
|
||||||
|
|
||||||
Example for 66AK2G:
|
|
||||||
|
|
||||||
gpio0: gpio@2603000 {
|
|
||||||
compatible = "ti,k2g-gpio", "ti,keystone-gpio";

|

gpio-controller;
|
|

#gpio-cells = <2>;
|
|
||||||
interrupts = <GIC_SPI 432 IRQ_TYPE_EDGE_RISING>,
|
|

|

};
|
|

|
|
