1* Altera Arria10 Development Kit System Resource Chip 2 3Required parent device properties: 4- compatible : "altr,a10sr" 5- spi-max-frequency : Maximum SPI frequency. 6- reg : The SPI Chip Select address for the Arria10 7 System Resource chip 8- interrupts : The interrupt line the device is connected to. 9- interrupt-controller : Marks the device node as an interrupt controller. 10- #interrupt-cells : The number of cells to describe an IRQ, should be 2. 11 The first cell is the IRQ number. 12 The second cell is the flags, encoded as trigger 13 masks from ../interrupt-controller/interrupts.txt. 14 15The A10SR consists of these sub-devices: 16 17Device Description 18------ ---------- 19a10sr_gpio GPIO Controller 20a10sr_rst Reset Controller 21 22Arria10 GPIO 23Required Properties: 24- compatible : Should be "altr,a10sr-gpio" 25- gpio-controller : Marks the device node as a GPIO Controller. 26- #gpio-cells : Should be two. The first cell is the pin number and 27 the second cell is used to specify flags. 28 See ../gpio/gpio.txt for more information. 29 30Arria10 Peripheral PHY Reset 31Required Properties: 32- compatible : Should be "altr,a10sr-reset" 33- #reset-cells : Should be one. 34 35Example: 36 37 resource-manager@0 { 38 compatible = "altr,a10sr"; 39 reg = <0>; 40 spi-max-frequency = <100000>; 41 interrupt-parent = <&portb>; 42 interrupts = <5 IRQ_TYPE_LEVEL_LOW>; 43 interrupt-controller; 44 #interrupt-cells = <2>; 45 46 a10sr_gpio: gpio-controller { 47 compatible = "altr,a10sr-gpio"; 48 gpio-controller; 49 #gpio-cells = <2>; 50 }; 51 52 a10sr_rst: reset-controller { 53 compatible = "altr,a10sr-reset"; 54 #reset-cells = <1>; 55 }; 56 }; 57
