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"
- reg-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>;
reg = <0>, <1>, <2>, <3>;
reg-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";
};
};
