+/*
+ * DOC: FCP (Focusrite Control Protocol) User-Space API
+ *
+ * This header defines the interface between the FCP kernel driver and
+ * user-space programs to enable the use of the proprietary features
+ * available in Focusrite USB audio interfaces. This includes Scarlett
+ * 2nd Gen, 3rd Gen, 4th Gen, Clarett USB, Clarett+, and Vocaster
+ * series devices.
+ *
+ * The interface is provided via ALSA's hwdep interface. Opening the
+ * hwdep device requires CAP_SYS_RAWIO privileges as this interface
+ * provides near-direct access.
+ *
+ * For details on the FCP protocol, refer to the kernel scarlett2
+ * driver in sound/usb/mixer_scarlett2.c and the fcp-support project
+ * at https://github.com/geoffreybennett/fcp-support
+ *
+ * For examples of using these IOCTLs, see the fcp-server source in
+ * the fcp-support project.
+ *
+ * IOCTL Interface
+ * --------------
+ * FCP_IOCTL_PVERSION:
+ * Returns the protocol version supported by the driver.
+ *
+ * FCP_IOCTL_INIT:
+ * Initialises the protocol and synchronises sequence numbers
+ * between the driver and device. Must be called at least once
+ * before sending commands. Can be safely called again at any time.
+ *
+ * FCP_IOCTL_CMD:
+ * Sends an FCP command to the device and returns the response.
+ * Requires prior initialisation via FCP_IOCTL_INIT.
+ *
+ * FCP_IOCTL_SET_METER_MAP:
+ * Configures the Level Meter control's mapping between device
+ * meters and control channels. Requires FCP_IOCTL_INIT to have been
+ * called first. The map size and number of slots cannot be changed
+ * after initial configuration, although the map itself can be
+ * updated. Once configured, the Level Meter remains functional even
+ * after the hwdep device is closed.
+ *
+ * FCP_IOCTL_SET_METER_LABELS:
+ * Set the labels for the Level Meter control. Requires
+ * FCP_IOCTL_SET_METER_MAP to have been called first. labels[]
+ * should contain a sequence of null-terminated labels corresponding
+ * to the control's channels.
