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/).
