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