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"; | |
