Filename should match compatibles. nokia,n9-modem.yaml or nokia,modem.yaml

Aren't hsi-channel-ids related to hsi-channel-names? If so, they should
be here with constraints.

This should be "modem".

Ack, I will switch to nokia,modem.yaml in v2.

Indeed. I forgot them, since they were not in the old binding :)
I will constraint them to min/max items 4 in v2.

-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-names = "mcsaab-control",
