| 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 | "nokia,n950-modem" |
| 11 | "nokia,n9-modem" |
| 12 | - hsi-channel-names: Should contain the following strings |
| 13 | "mcsaab-control" |
| 14 | "speech-control" |
| 15 | "speech-data" |
| 16 | "mcsaab-data" |
| 17 | - gpios: Should provide a GPIO handler for each GPIO listed in |
| 18 | gpio-names |
| 19 | - gpio-names: Should contain the following strings |
| 20 | "cmt_apeslpx" (for n900, n950, n9) |
| 21 | "cmt_rst_rq" (for n900, n950, n9) |
| 22 | "cmt_en" (for n900, n950, n9) |
| 23 | "cmt_rst" (for n900) |
| 24 | "cmt_bsi" (for n900) |
| 25 | - interrupts: Should be IRQ handle for modem's reset indication |
| 26 | |
| 27 | Example: |
| 28 | |
| 29 | &ssi_port { |
| 30 | modem: hsi-client { |
| 31 | compatible = "nokia,n900-modem"; |
| 32 | |
| 33 | pinctrl-names = "default"; |
| 34 | pinctrl-0 = <&modem_pins>; |
| 35 | |
| 36 | hsi-channel-ids = <0>, <1>, <2>, <3>; |
| 37 | hsi-channel-names = "mcsaab-control", |
| 38 | "speech-control", |
| 39 | "speech-data", |
| 40 | "mcsaab-data"; |
| 41 | hsi-speed-kbps = <55000>; |
| 42 | hsi-mode = "frame"; |
| 43 | hsi-flow = "synchronized"; |
| 44 | hsi-arb-mode = "round-robin"; |
| 45 | |
| 46 | interrupts-extended = <&gpio3 8 IRQ_TYPE_EDGE_FALLING>; /* 72 */ |
| 47 | |
| 48 | gpios = <&gpio3 6 GPIO_ACTIVE_HIGH>, /* 70 */ |
| 49 | <&gpio3 9 GPIO_ACTIVE_HIGH>, /* 73 */ |
| 50 | <&gpio3 10 GPIO_ACTIVE_HIGH>, /* 74 */ |
| 51 | <&gpio3 11 GPIO_ACTIVE_HIGH>, /* 75 */ |
| 52 | <&gpio5 29 GPIO_ACTIVE_HIGH>; /* 157 */ |
| 53 | gpio-names = "cmt_apeslpx", |
| 54 | "cmt_rst_rq", |
| 55 | "cmt_en", |
| 56 | "cmt_rst", |
| 57 | "cmt_bsi"; |
| 58 | }; |
| 59 | }; |
