| 2 | |
| 3 | Required properties: |
| 4 | - compatible : "silead,gsl1680" |
| 5 | - reg : I2C slave address of the chip (0x40) |
| 6 | - interrupt-parent : a phandle pointing to the interrupt controller |
| 7 | serving the interrupt for this chip |
| 8 | - interrupts : interrupt specification for the gsl1680 interrupt |
| 9 | - power-gpios : Specification for the pin connected to the gsl1680's |
| 10 | shutdown input. This needs to be driven high to take the |
| 11 | gsl1680 out of its low power state |
| 12 | - touchscreen-size-x : See touchscreen.txt |
| 13 | - touchscreen-size-y : See touchscreen.txt |
| 14 | |
| 15 | Optional properties: |
| 16 | - touchscreen-inverted-x : See touchscreen.txt |
| 17 | - touchscreen-inverted-y : See touchscreen.txt |
| 18 | - touchscreen-swapped-x-y : See touchscreen.txt |
| 19 | - silead,max-fingers : maximum number of fingers the touchscreen can detect |
| 20 | |
| 21 | Example: |
| 22 | |
| 23 | i2c@00000000 { |
| 24 | gsl1680: touchscreen@40 { |
| 25 | compatible = "silead,gsl1680"; |
| 26 | reg = <0x40>; |
| 27 | interrupt-parent = <&pio>; |
| 28 | interrupts = <6 11 IRQ_TYPE_EDGE_FALLING>; |
| 29 | power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>; |
| 30 | touchscreen-size-x = <480>; |
| 31 | touchscreen-size-y = <800>; |
| 32 | touchscreen-inverted-x; |
| 33 | touchscreen-swapped-x-y; |
| 34 | silead,max-fingers = <5>; |
| 35 | }; |
| 36 | }; |
