I am trying to interface WM-BAC-BM28 module via UART to IMX6SX. Please provide me the device tree, GPIO configuration and other required details.

Thanks..

Hello.

Sorry, can't help here. This is UART device, while broadcom-bt-firmware aimed to PCIe/USB SoC device family. As I can see from your output, there no firmware issues related to BCM chipsets.
