Subject[PATCH v4 1/3] dt-bindings: uwb: Device tree information for Nxp SR1XX SOCs
Date
Ultra-wideband (UWB) is a short-range wireless communication protocol.

NXP has SR1XX family of UWB Subsystems (UWBS) devices. SR1XX SOCs
are FiRa Compliant. SR1XX SOCs are flash less devices and they need
Firmware Download on every device boot. More details on the SR1XX Family
can be found at https://www.nxp.com/products/:UWB-TRIMENSION

The sr1xx driver work the SR1XX Family of UWBS, and uses UWB Controller
Interface (UCI). The corresponding details are available in the FiRa
Consortium Website (https://www.firaconsortium.org/).
