Subject: [PATCH v7 1/3] dt-bindings: net: Add ti,cc1352p7

Add DT bindings for Texas Instruments Simplelink CC1352P7 wireless MCU

BeaglePlay has CC1352P7 co-processor connected to the main AM62 (running
Linux) over UART. In the BeagleConnect Technology, CC1352 is responsible
for handling 6LoWPAN communication with beagleconnect freedom nodes as
well as their discovery.

It is used by gb-beagleplay greybus driver.
