1*4882a593Smuzhiyun* Elan eKTF2127 I2C touchscreen controller 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunRequired properties: 4*4882a593Smuzhiyun - compatible : "elan,ektf2127" 5*4882a593Smuzhiyun - reg : I2C slave address of the chip (0x40) 6*4882a593Smuzhiyun - interrupts : interrupt specification for the ektf2127 interrupt 7*4882a593Smuzhiyun - power-gpios : GPIO specification for the pin connected to the 8*4882a593Smuzhiyun ektf2127's wake input. This needs to be driven high 9*4882a593Smuzhiyun to take ektf2127 out of it's low power state 10*4882a593Smuzhiyun 11*4882a593SmuzhiyunFor additional optional properties see: touchscreen.txt 12*4882a593Smuzhiyun 13*4882a593SmuzhiyunExample: 14*4882a593Smuzhiyun 15*4882a593Smuzhiyuni2c@00000000 { 16*4882a593Smuzhiyun ektf2127: touchscreen@15 { 17*4882a593Smuzhiyun compatible = "elan,ektf2127"; 18*4882a593Smuzhiyun reg = <0x15>; 19*4882a593Smuzhiyun interrupt-parent = <&pio>; 20*4882a593Smuzhiyun interrupts = <6 11 IRQ_TYPE_EDGE_FALLING> 21*4882a593Smuzhiyun power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>; 22*4882a593Smuzhiyun touchscreen-inverted-x; 23*4882a593Smuzhiyun touchscreen-swapped-x-y; 24*4882a593Smuzhiyun }; 25*4882a593Smuzhiyun}; 26
