1 | Nokia modem client bindings |
| 2 | ||
| 3 | The Nokia modem HSI client follows the common HSI client binding | |
| 4 | and inherits all required properties. The following additional | |
| 5 | properties are needed by the Nokia modem HSI client: | |
| 6 | ||
| 7 | Required properties: | |
| 8 | - compatible: Should be one of | |
| 9 | "nokia,n900-modem" | |
| 10 | - hsi-channel-names: Should contain the following strings | |
| 11 | "mcsaab-control" | |
| 12 | "speech-control" | |
| 13 | "speech-data" | |
| 14 | "mcsaab-data" | |
| 15 | - gpios: Should provide a GPIO handler for each GPIO listed in | |
| 16 | gpio-names | |
| 17 | - gpio-names: Should contain the following strings | |
| 18 | "cmt_apeslpx" | |
| 19 | "cmt_rst_rq" | |
| 20 | "cmt_en" | |
| 21 | "cmt_rst" | |
| 22 | "cmt_bsi" | |
| 23 | - interrupts: Should be IRQ handle for modem's reset indication | |
| 24 | ||
| 25 | Example: | |
| 26 | ||
| 27 | &ssi_port { | |
| 28 | modem: hsi-client { | |
| 29 | compatible = "nokia,n900-modem"; | |
| 30 | ||

| 32 | pinctrl-0 = <&modem_pins>; | |

| 35 | hsi-channel-names = "mcsaab-control", | |
| 36 | "speech-control", | |
| 37 | "speech-data", | |
| 38 | "mcsaab-data"; | |
| 39 | hsi-speed-kbps = <55000>; | |
| 40 | hsi-mode = "frame"; | |
| 41 | hsi-flow = "synchronized"; | |
| 42 | hsi-arb-mode = "round-robin"; | |
| 43 | ||
| 44 | interrupts-extended = <&gpio3 8 IRQ_TYPE_EDGE_FALLING>; /* 72 */ | |
