* Altera Arria10 Development Kit System Resource Chip
Required parent device properties:
- compatible : "altr,a10sr"
- spi-max-frequency : Maximum SPI frequency.
- reg : The SPI Chip Select address for the Arria10
System Resource chip
- interrupt-parent : The parent interrupt controller.
- interrupts : The interrupt line the device is connected to.
- interrupt-controller : Marks the device node as an interrupt controller.
- #interrupt-cells : The number of cells to describe an IRQ, should be 2.
The first cell is the IRQ number.
The second cell is the flags, encoded as trigger
masks from ../interrupt-controller/interrupts.txt.
The A10SR consists of these sub-devices:
Device Description
------ ----------
a10sr_gpio GPIO Controller
a10sr_rst Reset Controller
Arria10 GPIO
Required Properties:
- compatible : Should be "altr,a10sr-gpio"
- gpio-controller : Marks the device node as a GPIO Controller.
- #gpio-cells : Should be two. The first cell is the pin number and
the second cell is used to specify flags.
See ../gpio/gpio.txt for more information.
Arria10 Peripheral PHY Reset
Required Properties:
- compatible : Should be "altr,a10sr-reset"
- #reset-cells : Should be one.
Example:
resource-manager@0 {
compatible = "altr,a10sr";
reg = <0>;
spi-max-frequency = <100000>;
interrupt-parent = <&portb>;
interrupts = <5 IRQ_TYPE_LEVEL_LOW>;
interrupt-controller;
#interrupt-cells = <2>;
a10sr_gpio: gpio-controller {
compatible = "altr,a10sr-gpio";
gpio-controller;
#gpio-cells = <2>;
};
a10sr_rst: reset-controller {
compatible = "altr,a10sr-reset";
#reset-cells = <1>;
};
};
