* 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>; }; };
