-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";
- };
