* 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 { |

|
reg = <0x40>; |
|
interrupt-parent = <&pio>; |
|
interrupts = <6 11 IRQ_TYPE_EDGE_FALLING>; |
|
