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";
|
||||
reg = <0x02603000 0x100>;
|
||||
gpio-controller;
|
||||
#gpio-cells = <2>;
|
||||
interrupts = <GIC_SPI 432 IRQ_TYPE_EDGE_RISING>,
|
||||
<GIC_SPI 433 IRQ_TYPE_EDGE_RISING>,
|
||||
<GIC_SPI 434 IRQ_TYPE_EDGE_RISING>,
|

<GIC_SPI 435 IRQ_TYPE_EDGE_RISING>,
|
||||
<GIC_SPI 436 IRQ_TYPE_EDGE_RISING>,
|

<GIC_SPI 437 IRQ_TYPE_EDGE_RISING>,

|
||||
<GIC_SPI 439 IRQ_TYPE_EDGE_RISING>,
|

<GIC_SPI 440 IRQ_TYPE_EDGE_RISING>;
|

|

ti,davinci-gpio-unbanked = <0>;

clocks = <&k2g_clks 0x001b 0x0>;

clock-names = "gpio";
|
