Each HSI port is supposed to have one child node, which symbols the remote device connected to the HSI port. The following properties are standardized for HSI clients: Required HSI configuration properties: - hsi-channel-ids: A list of channel ids - hsi-rx-mode: Receiver Bit transmission mode ("stream" or "frame") - hsi-tx-mode: Transmitter Bit transmission mode ("stream" or "frame") - hsi-mode: May be used instead hsi-rx-mode and hsi-tx-mode if the transmission mode is the same for receiver and transmitter - hsi-speed-kbps: Max bit transmission speed in kbit/s - hsi-flow: RX flow type ("synchronized" or "pipeline") - hsi-arb-mode: Arbitration mode for TX frame ("round-robin", "priority") Optional HSI configuration properties: - hsi-channel-names: A list with one name per channel specified in the hsi-channel-ids property Device Tree node example for an HSI client: hsi-controller { hsi-port { modem: hsi-client { compatible = "nokia,n900-modem"; hsi-channel-ids = <0>, <1>, <2>, <3>; hsi-channel-names = "mcsaab-control", "speech-control", "speech-data", "mcsaab-data"; hsi-speed-kbps = <55000>; hsi-mode = "frame"; hsi-flow = "synchronized"; hsi-arb-mode = "round-robin"; /* more client specific properties */ }; }; };
