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"
|
|
- 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"
|
|
"cmt_rst_rq"
|
|
"cmt_en"
|
|
"cmt_rst"
|
|
"cmt_bsi"
|
|
- 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";
|
