* FM Driver for Connectivity chip of Texas Instruments.
*
* This sub-module of FM driver is common for FM RX and TX
* functionality. This module is responsible for:
* 1) Forming group of Channel-8 commands to perform particular
* functionality (eg., frequency set require more than
* one Channel-8 command to be sent to the chip).
* 2) Sending each Channel-8 command to the chip and reading
* response back over Shared Transport.
* 3) Managing TX and RX Queues and Tasklets.
* 4) Handling FM Interrupt packet and taking appropriate action.
* 5) Loading FM firmware to the chip (common, FM TX, and FM RX
* firmware files based on mode selection)
