1 | Each HSI port is supposed to have one child node, which |
| 2 | symbols the remote device connected to the HSI port. The | |
| 3 | following properties are standardized for HSI clients: | |
| 4 | ||
| 5 | Required 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 | ||
| 18 | Optional 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 | ||
| 24 | Device Tree node example for an HSI client: | |
| 25 | ||
| 26 | hsi-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 | }; |
