1Nokia modem client bindings
2
3The Nokia modem HSI client follows the common HSI client binding
4and inherits all required properties. The following additional
5properties are needed by the Nokia modem HSI client:
6
7Required 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
