           : ACPI entries in SSDT for ELAN according to CBI fw_config.
           : 
           : THC0 must be enabled when THC1 is enabled.
           : Major rework is required for Rex P1 and P2. minor Rework is needed for
           : EVT. Rex with THC rework won't be able to support UWB and FPCMU.

           : When THC is enabled and the THC rework is in place, the UWB and FPMCU
           : are not supported and need to be disable from the CBI.
