1*80f93c7bSSrinivas KandagatlaDevice-Tree bindings for ST IRB IP 2*80f93c7bSSrinivas Kandagatla 3*80f93c7bSSrinivas KandagatlaRequired properties: 4*80f93c7bSSrinivas Kandagatla - compatible: Should contain "st,comms-irb". 5*80f93c7bSSrinivas Kandagatla - reg: Base physical address of the controller and length of memory 6*80f93c7bSSrinivas Kandagatla mapped region. 7*80f93c7bSSrinivas Kandagatla - interrupts: interrupt-specifier for the sole interrupt generated by 8*80f93c7bSSrinivas Kandagatla the device. The interrupt specifier format depends on the interrupt 9*80f93c7bSSrinivas Kandagatla controller parent. 10*80f93c7bSSrinivas Kandagatla - rx-mode: can be "infrared" or "uhf". This property specifies the L1 11*80f93c7bSSrinivas Kandagatla protocol used for receiving remote control signals. rx-mode should 12*80f93c7bSSrinivas Kandagatla be present iff the rx pins are wired up. 13*80f93c7bSSrinivas Kandagatla - tx-mode: should be "infrared". This property specifies the L1 14*80f93c7bSSrinivas Kandagatla protocol used for transmitting remote control signals. tx-mode should 15*80f93c7bSSrinivas Kandagatla be present iff the tx pins are wired up. 16*80f93c7bSSrinivas Kandagatla 17*80f93c7bSSrinivas KandagatlaOptional properties: 18*80f93c7bSSrinivas Kandagatla - pinctrl-names, pinctrl-0: the pincontrol settings to configure muxing 19*80f93c7bSSrinivas Kandagatla properly for IRB pins. 20*80f93c7bSSrinivas Kandagatla - clocks : phandle with clock-specifier pair for IRB. 21*80f93c7bSSrinivas Kandagatla 22*80f93c7bSSrinivas KandagatlaExample node: 23*80f93c7bSSrinivas Kandagatla 24*80f93c7bSSrinivas Kandagatla rc: rc@fe518000 { 25*80f93c7bSSrinivas Kandagatla compatible = "st,comms-irb"; 26*80f93c7bSSrinivas Kandagatla reg = <0xfe518000 0x234>; 27*80f93c7bSSrinivas Kandagatla interrupts = <0 203 0>; 28*80f93c7bSSrinivas Kandagatla rx-mode = "infrared"; 29*80f93c7bSSrinivas Kandagatla }; 30
