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 "synaptics,dsx-i2c". - - reg : i2c slave address of the device. - - interrupt-parent : parent of interrupt. - - synaptics,irq-gpio : irq gpio. - - synaptics,irq-flags : irq flags. - -Optional property: - - vdd_ana-supply : digital voltage power supply needed to power device. - - vcc_i2c-supply : analog voltage power supply needed to power device. - - synaptics,pwr-reg-name : power reg name of digital voltage. - - synaptics,bus-reg-name : bus reg name of analog voltage. - - synaptics,irq-on-state : status of irq gpio. - - synaptics,cap-button-codes : virtual key code mappings to be used. - - synaptics,vir-button-codes : virtual key code and the response region on panel. - - synaptics,x-flip : modify orientation of the x axis. - - synaptics,y-flip : modify orientation of the y axis. - - synaptics,reset-delay-ms : reset delay for controller (ms), default 100. - - synaptics,max-y-for-2d : maximal y value of the panel. - - clock-names : Clock names used for secure touch. They are: "iface_clk", "core_clk" - - clocks : Defined if 'clock-names' DT property is defined.
