Subject: [PATCH 3/3] dt-bindings: net: ti,bluetooth: Convert to json-schema
Convert the Texas Instruments serial-attached bluetooth Device Tree
binding documentation to json-schema.
Add missing max-speed property.
Update the example.
Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>

I listed David as maintainer, as he wrote the original bindings.
Please scream if not appropriate.

+
+ TI WiLink devices have a UART interface for providing Bluetooth, FM radio,
+ and GPS over what's called "shared transport". The shared transport is
+ standard BT HCI protocol with additional channels for the other functions.
+
+ TI WiLink devices also have a separate WiFi interface as described in
+ wireless/ti,wlcore.yaml.
+
+ This bindings follows the UART slave device binding in ../serial/serial.yaml.

-Texas Instruments Bluetooth Chips
----------------------------------
-
-This documents the binding structure and common properties for serial
-attached TI Bluetooth devices. The following chips are included in this
-binding:
-
-* TI CC256x Bluetooth devices
-* TI WiLink 7/8 (wl12xx/wl18xx) Shared Transport BT/FM/GPS devices
-
-TI WiLink devices have a UART interface for providing Bluetooth, FM radio,
-and GPS over what's called "shared transport". The shared transport is
-standard BT HCI protocol with additional channels for the other functions.
-
-TI WiLink devices also have a separate WiFi interface as described in
-wireless/ti,wlcore.yaml.
-
-This bindings follows the UART slave device binding in ../serial/serial.yaml.
-
-Required properties:
- - compatible: should be one of the following:
- "ti,cc2560"
- "ti,wl1271-st"
- "ti,wl1273-st"
- "ti,wl1281-st"
- "ti,wl1283-st"
- "ti,wl1285-st"
- "ti,wl1801-st"
- "ti,wl1805-st"
- "ti,wl1807-st"
- "ti,wl1831-st"
- "ti,wl1835-st"
- "ti,wl1837-st"
-
-Optional properties:
- - enable-gpios : GPIO signal controlling enabling of BT. Active high.
- - vio-supply : Vio input supply (1.8V)
- - vbat-supply : Vbat input supply (2.9-4.8V)
- - clocks : Must contain an entry, for each entry in clock-names.
- See ../clocks/clock-bindings.txt for details.
- - clock-names : Must include the following entry:
- "ext_clock" (External clock provided to the TI combo chip).
- - nvmem-cells: phandle to nvmem data cell that contains a 6 byte BD address
- with the most significant byte first (big-endian).
- - nvmem-cell-names: "bd-address" (required when nvmem-cells is specified)
-
-Example:
-
-&serial0 {
- compatible = "ns16550a";
- ...
- bluetooth {
- compatible = "ti,wl1835-st";
- enable-gpios = <&gpio1 7 GPIO_ACTIVE_HIGH>;
- clocks = <&clk32k_wl18xx>;
- clock-names = "ext_clock";
- nvmem-cells = <&bd_address>;
- nvmem-cell-names = "bd-address";
- };
-};
