+/**
+ * DOC: Chip basics
+ *
+ * Each physical device of ours is a separate chip, that is being described by
+ * %cl_chip structure. Each chip may be several (%TCV_MAX) transceivers (bands),
+ * which are operating simultaneously and are described via own %ieee80211_hw
+ * unit (it refers to the private driver via specific pointer, described by
+ * %cl_hw). Totally, 3 types of bands are supported - 2.4G/5.2G/6G. Driver
+ * supports multiple chips (up to %CHIP_MAX). Since the driver can control up
+ * to %TCV_TOTAL entities, it is important to pass it's pointer to each
+ * function, that operates somehow with specific band/transceiver.
+ *
+ * Chip instance is being created during bus probing procedure and is being
+ * destroyed during bus removal procedure.
+ *
+ * Physically, 80xx chips family may have different amount of antennas (4/6/8),
+ * each of which may not be hardly bounded to the specific band (both bands are
+ * sharing them and may change antenna combinations in specific circumstances).
+ *
+ * Each band (transceiver) has own FW, that is being loaded by
+ * request_firmware() call during chip structure initialization procedure. At
+ * lower layer each band is associated with own HW die by LMAC and SMAC names
+ * (e.g: 5.2G and 2.4G). Celeno is using XMAC naming when we are referring to any
+ * of LMAC/SMAC components.
