+Subject: [PATCH 09/15] drivers:media:radio: wl128x: FM Driver Common sources
+
+These are the sources for the common interfaces required by the
+FM V4L2 driver for TI WL127x and WL128x chips.
+
+These implement the FM channel-8 protocol communication with the
+chip. This makes use of the Shared Transport as its transport.

++ * 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)
