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.txt. + +This bindings follows the UART slave device binding in +../serial/slave-device.txt. + +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.
