| Nokia modem client bindings |
| |
| The Nokia modem HSI client follows the common HSI client binding |
| and inherits all required properties. The following additional |
| properties are needed by the Nokia modem HSI client: |
| |
| Required properties: |
| - compatible: Should be one of |
| "nokia,n900-modem" |
| "nokia,n950-modem" |
| "nokia,n9-modem" |
| - hsi-channel-names: Should contain the following strings |
| "mcsaab-control" |
| "speech-control" |
| "speech-data" |
| "mcsaab-data" |
| - gpios: Should provide a GPIO handler for each GPIO listed in |
| gpio-names |
| - gpio-names: Should contain the following strings |
| "cmt_apeslpx" (for n900, n950, n9) |
| "cmt_rst_rq" (for n900, n950, n9) |
| "cmt_en" (for n900, n950, n9) |
| "cmt_rst" (for n900) |
| "cmt_bsi" (for n900) |
| - interrupts: Should be IRQ handle for modem's reset indication |
| |
| Example: |
| |
| &ssi_port { |
| modem: hsi-client { |
| compatible = "nokia,n900-modem"; |
| |
| pinctrl-names = "default"; |
| pinctrl-0 = <&modem_pins>; |
| |
| 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"; |
| |
| interrupts-extended = <&gpio3 8 IRQ_TYPE_EDGE_FALLING>; /* 72 */ |
| |
| gpios = <&gpio3 6 GPIO_ACTIVE_HIGH>, /* 70 */ |
| <&gpio3 9 GPIO_ACTIVE_HIGH>, /* 73 */ |
| <&gpio3 10 GPIO_ACTIVE_HIGH>, /* 74 */ |
| <&gpio3 11 GPIO_ACTIVE_HIGH>, /* 75 */ |
| <&gpio5 29 GPIO_ACTIVE_HIGH>; /* 157 */ |
| gpio-names = "cmt_apeslpx", |
| "cmt_rst_rq", |
| "cmt_en", |
| "cmt_rst", |
| "cmt_bsi"; |
| }; |
| }; |
