1Each HSI port is supposed to have one child node, which 2symbols the remote device connected to the HSI port. The 3following properties are standardized for HSI clients: 4 5Required HSI configuration properties: 6 7- hsi-channel-ids: A list of channel ids 8 9- hsi-rx-mode: Receiver Bit transmission mode ("stream" or "frame") 10- hsi-tx-mode: Transmitter Bit transmission mode ("stream" or "frame") 11- hsi-mode: May be used instead hsi-rx-mode and hsi-tx-mode if 12 the transmission mode is the same for receiver and 13 transmitter 14- hsi-speed-kbps: Max bit transmission speed in kbit/s 15- hsi-flow: RX flow type ("synchronized" or "pipeline") 16- hsi-arb-mode: Arbitration mode for TX frame ("round-robin", "priority") 17 18Optional HSI configuration properties: 19 20- hsi-channel-names: A list with one name per channel specified in the 21 hsi-channel-ids property 22 23 24Device Tree node example for an HSI client: 25 26hsi-controller { 27 hsi-port { 28 modem: hsi-client { 29 compatible = "nokia,n900-modem"; 30 31 hsi-channel-ids = <0>, <1>, <2>, <3>; 32 hsi-channel-names = "mcsaab-control", 33 "speech-control", 34 "speech-data", 35 "mcsaab-data"; 36 hsi-speed-kbps = <55000>; 37 hsi-mode = "frame"; 38 hsi-flow = "synchronized"; 39 hsi-arb-mode = "round-robin"; 40 41 /* more client specific properties */ 42 }; 43 }; 44};
