Convert generic PWM bindings to DT schema format using json-schema.  The
consumer bindings are split to separate file.

+description: |
+  PWM properties should be named "pwms". The exact meaning of each pwms
+  property must be documented in the device tree binding for each device.
+  An optional property "pwm-names" may contain a list of strings to label
+  each of the PWM devices listed in the "pwms" property. If no "pwm-names"
+  property is given, the name of the user node will be used as fallback.
+
+  Drivers for devices that use more than a single PWM device can use the
+  "pwm-names" property to map the name of the PWM device requested by the
+  pwm_get() call to an index into the list given by the "pwms" property.
+
+properties:
+  pwms:
+    $ref: /schemas/types.yaml#/definitions/phandle-array
+    description: |
+      Phandle to PWM controller node and pwm-specifier (controller specific).
+      pwm-specifier typically encodes the chip-relative PWM number and the PWM
+      period in nanoseconds.
+      Optionally, the pwm-specifier can encode a number of flags (defined in
+      <dt-bindings/pwm/pwm.h>) in a third cell:
+        - PWM_POLARITY_INVERTED: invert the PWM signal polarity
+
+  pwm-names:
+    $ref: /schemas/types.yaml#/definitions/string-array
+    description:
+      A list of strings to label each of the PWM devices listed in the "pwms"
+      property. If no "pwm-names" property is given, the name of the user node
+      will be used as fallback.
+

+    // The following example could be used to describe a PWM-based
+    // backlight device:
+
+    pwm: pwm {
+      #pwm-cells = <2>;

-Specifying PWM information for devices
-======================================
-
-1) PWM user nodes
------------------
-
-PWM users should specify a list of PWM devices that they want to use
-with a property containing a 'pwm-list':
-
-	pwm-list ::= <single-pwm> [pwm-list]
-	single-pwm ::= <pwm-phandle> <pwm-specifier>
-	pwm-phandle : phandle to PWM controller node
-	pwm-specifier : array of #pwm-cells specifying the given PWM
-			(controller specific)
-
-PWM properties should be named "pwms". The exact meaning of each pwms
-property must be documented in the device tree binding for each device.
-An optional property "pwm-names" may contain a list of strings to label
-each of the PWM devices listed in the "pwms" property. If no "pwm-names"
-property is given, the name of the user node will be used as fallback.
-
-Drivers for devices that use more than a single PWM device can use the
-"pwm-names" property to map the name of the PWM device requested by the
-pwm_get() call to an index into the list given by the "pwms" property.
-
-The following example could be used to describe a PWM-based backlight
-device:
-
-	pwm: pwm {
-		#pwm-cells = <2>;
-	};
-
-	[...]
-
-	bl: backlight {
-		pwms = <&pwm 0 5000000>;
-		pwm-names = "backlight";
-	};
-
-Note that in the example above, specifying the "pwm-names" is redundant
-because the name "backlight" would be used as fallback anyway.
-
-pwm-specifier typically encodes the chip-relative PWM number and the PWM
-period in nanoseconds.
-
-Optionally, the pwm-specifier can encode a number of flags (defined in
-<dt-bindings/pwm/pwm.h>) in a third cell:
-- PWM_POLARITY_INVERTED: invert the PWM signal polarity
-
-Example with optional PWM specifier for inverse polarity
-
-	bl: backlight {
-		pwms = <&pwm 0 5000000 PWM_POLARITY_INVERTED>;
-		pwm-names = "backlight";
-	};
-
-2) PWM controller nodes
------------------------
-
-PWM controller nodes must specify the number of cells used for the
-specifier using the '#pwm-cells' property.
-
-An example PWM controller might look like this:
-
-	pwm: pwm@7000a000 {
-		compatible = "nvidia,tegra20-pwm";
-		reg = <0x7000a000 0x100>;
-		#pwm-cells = <2>;
-	};
