Raydium WT030 touch controller
|
|
|
|
Please add this description here: The Raydium Touch controller is connected to the
|
|
host processor via I2C. The controller generates interrupts when the user touches
|
|
the panel. The host controller is expected to read the touch coordinates over I2C and
|
|
pass the coordinates to the rest of the system.
|
|
|
|
Required properties:
|
|
|
|
- compatible : should be "raydium,raydium-ts".
|
|
- reg : i2c slave address of the device.
|
|
- interrupt-parent : parent of interrupt.
|
|
- raydium,irq-gpio : irq gpio.
|
|
- raydium,reset-gpio : reset gpio.
|
|
- vdd_ana-supply : analog voltage power supply needed to power device.
|
|
- vcc_i2c-supply : i2c voltage power supply needed to power device.
|
|
|
|
Optional property:
|
|
- raydium,max-num-touches : addr of ub-i2c.
|
|
- raydium,display-coords : array of display coordinates.
|
|
- raydium,x_max : maximal x value of the panel.
|
|
- raydium,y_max : maximal y value of the panel.
|
|
- raydium,fw_id : firmare id.
|
|
- raydium,soft-reset-delay-ms : reset delay for controller (ms), default 100.
|
|
- raydium,hard-reset-delay-ms : reset delay for controller (ms), default 100.
|
|
