| 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 */ |
| }; |
| }; |
| }; |
