162306a36Sopenharmony_ciDevice-Tree bindings for ST IRB IP 262306a36Sopenharmony_ci 362306a36Sopenharmony_ciRequired properties: 462306a36Sopenharmony_ci - compatible: Should contain "st,comms-irb". 562306a36Sopenharmony_ci - reg: Base physical address of the controller and length of memory 662306a36Sopenharmony_ci mapped region. 762306a36Sopenharmony_ci - interrupts: interrupt-specifier for the sole interrupt generated by 862306a36Sopenharmony_ci the device. The interrupt specifier format depends on the interrupt 962306a36Sopenharmony_ci controller parent. 1062306a36Sopenharmony_ci - rx-mode: can be "infrared" or "uhf". This property specifies the L1 1162306a36Sopenharmony_ci protocol used for receiving remote control signals. rx-mode should 1262306a36Sopenharmony_ci be present iff the rx pins are wired up. 1362306a36Sopenharmony_ci - tx-mode: should be "infrared". This property specifies the L1 1462306a36Sopenharmony_ci protocol used for transmitting remote control signals. tx-mode should 1562306a36Sopenharmony_ci be present iff the tx pins are wired up. 1662306a36Sopenharmony_ci 1762306a36Sopenharmony_ciOptional properties: 1862306a36Sopenharmony_ci - pinctrl-names, pinctrl-0: the pincontrol settings to configure muxing 1962306a36Sopenharmony_ci properly for IRB pins. 2062306a36Sopenharmony_ci - clocks : phandle with clock-specifier pair for IRB. 2162306a36Sopenharmony_ci 2262306a36Sopenharmony_ciExample node: 2362306a36Sopenharmony_ci 2462306a36Sopenharmony_ci rc: rc@fe518000 { 2562306a36Sopenharmony_ci compatible = "st,comms-irb"; 2662306a36Sopenharmony_ci reg = <0xfe518000 0x234>; 2762306a36Sopenharmony_ci interrupts = <0 203 0>; 2862306a36Sopenharmony_ci rx-mode = "infrared"; 2962306a36Sopenharmony_ci }; 30
