1 Nokia modem client bindings
2
3 The Nokia modem HSI client follows the common HSI client binding
4 and inherits all required properties. The following additional
5 properties are needed by the Nokia modem HSI client:
6
7 Required properties:
8 - compatible: Should be one of
9 "nokia,n900-modem"
10 "nokia,n950-modem"
11 "nokia,n9-modem"
12 - hsi-channel-names: Should contain the following strings
13 "mcsaab-control"
14 "speech-control"
15 "speech-data"
16 "mcsaab-data"
17 - gpios: Should provide a GPIO handler for each GPIO listed in
18 gpio-names
19 - gpio-names: Should contain the following strings
20 "cmt_apeslpx" (for n900, n950, n9)
21 "cmt_rst_rq" (for n900, n950, n9)
22 "cmt_en" (for n900, n950, n9)
23 "cmt_rst" (for n900)
24 "cmt_bsi" (for n900)
25 - interrupts: Should be IRQ handle for modem's reset indication
26
27 Example:
28
29 &ssi_port {
30 modem: hsi-client {
31 compatible = "nokia,n900-modem";
32
33 pinctrl-names = "default";
34 pinctrl-0 = <&modem_pins>;
35
36 hsi-channel-ids = <0>, <1>, <2>, <3>;
37 hsi-channel-names = "mcsaab-control",
38 "speech-control",
39 "speech-data",
40 "mcsaab-data";
41 hsi-speed-kbps = <55000>;
42 hsi-mode = "frame";
43 hsi-flow = "synchronized";
44 hsi-arb-mode = "round-robin";
45
46 interrupts-extended = <&gpio3 8 IRQ_TYPE_EDGE_FALLING>; /* 72 */
47
48 gpios = <&gpio3 6 GPIO_ACTIVE_HIGH>, /* 70 */
49 <&gpio3 9 GPIO_ACTIVE_HIGH>, /* 73 */
50 <&gpio3 10 GPIO_ACTIVE_HIGH>, /* 74 */
51 <&gpio3 11 GPIO_ACTIVE_HIGH>, /* 75 */
52 <&gpio5 29 GPIO_ACTIVE_HIGH>; /* 157 */
53 gpio-names = "cmt_apeslpx",
54 "cmt_rst_rq",
55 "cmt_en",
56 "cmt_rst",
57 "cmt_bsi";
58 };
59 };
