1 | * Altera Arria10 Development Kit System Resource Chip |
2 | ||
3 | Required 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 | - interrupt-parent : The parent interrupt controller. | |
9 | - interrupts : The interrupt line the device is connected to. | |
10 | - interrupt-controller : Marks the device node as an interrupt controller. | |
11 | - #interrupt-cells : The number of cells to describe an IRQ, should be 2. | |
12 | The first cell is the IRQ number. | |
13 | The second cell is the flags, encoded as trigger | |
14 | masks from ../interrupt-controller/interrupts.txt. | |

66da627e | 21 | a10sr_rst Reset Controller |
7fff7d9b TT |
22 | |
23 | Arria10 GPIO | |
24 | Required Properties: | |
25 | - compatible : Should be "altr,a10sr-gpio" | |
26 | - gpio-controller : Marks the device node as a GPIO Controller. | |
27 | - #gpio-cells : Should be two. The first cell is the pin number and | |
28 | the second cell is used to specify flags. | |
