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"; |
|
}; |
|
};
