18c2ecf20Sopenharmony_ciDevice-Tree bindings for ST IRB IP 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciRequired properties: 48c2ecf20Sopenharmony_ci - compatible: Should contain "st,comms-irb". 58c2ecf20Sopenharmony_ci - reg: Base physical address of the controller and length of memory 68c2ecf20Sopenharmony_ci mapped region. 78c2ecf20Sopenharmony_ci - interrupts: interrupt-specifier for the sole interrupt generated by 88c2ecf20Sopenharmony_ci the device. The interrupt specifier format depends on the interrupt 98c2ecf20Sopenharmony_ci controller parent. 108c2ecf20Sopenharmony_ci - rx-mode: can be "infrared" or "uhf". This property specifies the L1 118c2ecf20Sopenharmony_ci protocol used for receiving remote control signals. rx-mode should 128c2ecf20Sopenharmony_ci be present iff the rx pins are wired up. 138c2ecf20Sopenharmony_ci - tx-mode: should be "infrared". This property specifies the L1 148c2ecf20Sopenharmony_ci protocol used for transmitting remote control signals. tx-mode should 158c2ecf20Sopenharmony_ci be present iff the tx pins are wired up. 168c2ecf20Sopenharmony_ci 178c2ecf20Sopenharmony_ciOptional properties: 188c2ecf20Sopenharmony_ci - pinctrl-names, pinctrl-0: the pincontrol settings to configure muxing 198c2ecf20Sopenharmony_ci properly for IRB pins. 208c2ecf20Sopenharmony_ci - clocks : phandle with clock-specifier pair for IRB. 218c2ecf20Sopenharmony_ci 228c2ecf20Sopenharmony_ciExample node: 238c2ecf20Sopenharmony_ci 248c2ecf20Sopenharmony_ci rc: rc@fe518000 { 258c2ecf20Sopenharmony_ci compatible = "st,comms-irb"; 268c2ecf20Sopenharmony_ci reg = <0xfe518000 0x234>; 278c2ecf20Sopenharmony_ci interrupts = <0 203 0>; 288c2ecf20Sopenharmony_ci rx-mode = "infrared"; 298c2ecf20Sopenharmony_ci }; 30
