| * GSL 1680 touchscreen controller |
| |
| Required properties: |
| - compatible : Must be one of the following, depending on the model: |
| "silead,gsl1680" |
| "silead,gsl1688" |
| "silead,gsl3670" |
| "silead,gsl3675" |
| "silead,gsl3692" |
| - reg : I2C slave address of the chip (0x40) |
| - interrupts : interrupt specification for the gsl1680 interrupt |
| - power-gpios : Specification for the pin connected to the gsl1680's |
| shutdown input. This needs to be driven high to take the |
| gsl1680 out of its low power state |
| - touchscreen-size-x : See touchscreen.txt |
| - touchscreen-size-y : See touchscreen.txt |
| |
| Optional properties: |
| - firmware-name : File basename (string) for board specific firmware |
| - touchscreen-inverted-x : See touchscreen.txt |
| - touchscreen-inverted-y : See touchscreen.txt |
| - touchscreen-swapped-x-y : See touchscreen.txt |
| - silead,max-fingers : maximum number of fingers the touchscreen can detect |
| - silead,home-button : Boolean, set to true on devices which have a |
| capacitive home-button build into the touchscreen |
| - vddio-supply : regulator phandle for controller VDDIO |
| - avdd-supply : regulator phandle for controller AVDD |
| |
| Example: |
| |
| i2c@00000000 { |
| gsl1680: touchscreen@40 { |
| compatible = "silead,gsl1680"; |
| reg = <0x40>; |
| interrupt-parent = <&pio>; |
| interrupts = <6 11 IRQ_TYPE_EDGE_FALLING>; |
| power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>; |
| touchscreen-size-x = <480>; |
| touchscreen-size-y = <800>; |
| touchscreen-inverted-x; |
| touchscreen-swapped-x-y; |
| silead,max-fingers = <5>; |
| }; |
| }; |
