+ *			memory mapped API, as defined by
+ *			&enum dmx_buffer_flags.
+ *
+ * This function callback prototype, provided by the client of the demux API,
+ * is called from the demux code. The function is only called when filtering
+ * on a TS feed has been enabled using the start_filtering\(\) function at
+ * the &dmx_demux.
+ * Any TS packets that match the filter settings are copied to a circular
+ * buffer. The filtered TS packets are delivered to the client using this
+ * callback function.
+ * It is expected that the @buffer1 and @buffer2 callback parameters point to
+ * addresses within the circular buffer, but other implementations are also
+ * possible. Note that the called party should not try to free the memory
+ * the @buffer1 and @buffer2 parameters point to.
+ *
+ * When this function is called, the @buffer1 parameter typically points to
+ * the start of the first undelivered TS packet within a circular buffer.
+ * The @buffer2 buffer parameter is normally NULL, except when the received
+ * TS packets have crossed the last address of the circular buffer and
+ * "wrapped" to the beginning of the buffer. In the latter case the @buffer1
+ * parameter would contain an address within the circular buffer, while the
+ * @buffer2 parameter would contain the first address of the circular buffer.
+ * The number of bytes delivered with this function (i.e. @buffer1_length +
+ * @buffer2_length) is usually equal to the value of callback_length parameter
+ * given in the set() function, with one exception: if a timeout occurs before
+ * receiving callback_length bytes of TS data, any undelivered packets are
+ * immediately delivered to the client by calling this function. The timeout
+ * duration is controlled by the set() function in the TS Feed API.
+ *
+ * If a TS packet is received with errors that could not be fixed by the
+ * TS-level forward error correction (FEC), the Transport_error_indicator
+ * flag of the TS packet header should be set. The TS packet should not be
+ * discarded, as the error can possibly be corrected by a higher layer
+ * protocol. If the called party is slow in processing the callback, it
+ * is possible that the circular buffer eventually fills up. If this happens,
+ * the demux driver should discard any TS packets received while the buffer
+ * is full and return -EOVERFLOW.
+ *
+ * The type of data returned to the callback can be selected by the
+ * &dmx_ts_feed.@set function. The type parameter decides if the raw
+ * TS packet (TS_PACKET) or just the payload (TS_PACKET|TS_PAYLOAD_ONLY)
+ * should be returned. If additionally the TS_DECODER bit is set the stream
+ * will also be sent to the hardware MPEG decoder.

+ *	-EINVAL, on bad parameter.
+ *
+ * @write: This function provides the demux driver with a memory buffer
+ *	containing TS packets. Instead of receiving TS packets from the DVB
+ *	front-end, the demux driver software will read packets from memory.
+ *	Any clients of this demux with active TS, PES or Section filters will
+ *	receive filtered data via the Demux callback API (see 0). The function
+ *	returns when all the data in the buffer has been consumed by the demux.
+ *	Demux hardware typically cannot read TS from memory. If this is the
+ *	case, memory-based filtering has to be implemented entirely in software.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @buf function parameter contains a pointer to the TS data in
+ *	kernel-space memory.
+ *	The @count function parameter contains the length of the TS data.
+ *	It returns:
+ *	0 on success;
+ *	-ERESTARTSYS, if mutex lock was interrupted;
+ *	-EINTR, if a signal handling is pending;
+ *	-ENODEV, if demux was removed;
+ *	-EINVAL, on bad parameter.
+ *
+ * @allocate_ts_feed: Allocates a new TS feed, which is used to filter the TS
+ *	packets carrying a certain PID. The TS feed normally corresponds to a
+ *	hardware PID filter on the demux chip.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	The @callback function parameter contains a pointer to the callback
+ *	function for passing received TS packet.
+ *	It returns:
+ *	0 on success;
+ *	-ERESTARTSYS, if mutex lock was interrupted;
+ *	-EBUSY, if no more TS feeds is available;
+ *	-EINVAL, on bad parameter.
+ *
+ * @release_ts_feed: Releases the resources allocated with @allocate_ts_feed.
+ *	Any filtering in progress on the TS feed should be stopped before
+ *	calling this function.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-EINVAL on bad parameter.
+ *
+ * @allocate_section_feed: Allocates a new section feed, i.e. a demux resource
+ *	for filtering and receiving sections. On platforms with hardware
+ *	support for section filtering, a section feed is directly mapped to
+ *	the demux HW. On other platforms, TS packets are first PID filtered in
+ *	hardware and a hardware section filter then emulated in software. The
+ *	caller obtains an API pointer of type dmx_section_feed_t as an out
+ *	parameter. Using this API the caller can set filtering parameters and
+ *	start receiving sections.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	The @callback function parameter contains a pointer to the callback
+ *	function for passing received TS packet.
+ *	It returns:
+ *	0 on success;
+ *	-EBUSY, if no more TS feeds is available;
+ *	-EINVAL, on bad parameter.
+ *
+ * @release_section_feed: Releases the resources allocated with
+ *	@allocate_section_feed, including allocated filters. Any filtering in
+ *	progress on the section feed should be stopped before calling this
+ *	function.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-EINVAL, on bad parameter.
+ *
+ * @add_frontend: Registers a connectivity between a demux and a front-end,
+ *	i.e., indicates that the demux can be connected via a call to
+ *	@connect_frontend to use the given front-end as a TS source. The
+ *	client of this function has to allocate dynamic or static memory for
+ *	the frontend structure and initialize its fields before calling this
+ *	function. This function is normally called during the driver
+ *	initialization. The caller must not free the memory of the frontend
+ *	struct before successfully calling @remove_frontend.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @frontend function parameter contains a pointer to the front-end
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-EINVAL, on bad parameter.
+ *
+ * @remove_frontend: Indicates that the given front-end, registered by a call
+ *	to @add_frontend, can no longer be connected as a TS source by this
+ *	demux. The function should be called when a front-end driver or a demux
+ *	driver is removed from the system. If the front-end is in use, the
+ *	function fails with the return value of -EBUSY. After successfully
+ *	calling this function, the caller can free the memory of the frontend
+ *	struct if it was dynamically allocated before the @add_frontend
+ *	operation.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @frontend function parameter contains a pointer to the front-end
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-ENODEV, if the front-end was not found,
+ *	-EINVAL, on bad parameter.
+ *
+ * @get_frontends: Provides the APIs of the front-ends that have been
+ *	registered for this demux. Any of the front-ends obtained with this
+ *	call can be used as a parameter for @connect_frontend. The include
+ *	file demux.h contains the macro DMX_FE_ENTRY() for converting an
+ *	element of the generic type struct &list_head * to the type
+ *	struct &dmx_frontend *. The caller must not free the memory of any of
+ *	the elements obtained via this function call.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	It returns a struct list_head pointer to the list of front-end
+ *	interfaces, or NULL in the case of an empty list.
+ *
+ * @connect_frontend: Connects the TS output of the front-end to the input of
+ *	the demux. A demux can only be connected to a front-end registered to
+ *	the demux with the function @add_frontend. It may or may not be
+ *	possible to connect multiple demuxes to the same front-end, depending
+ *	on the capabilities of the HW platform. When not used, the front-end
+ *	should be released by calling @disconnect_frontend.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @frontend function parameter contains a pointer to the front-end
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-EINVAL, on bad parameter.
+ *
+ * @disconnect_frontend: Disconnects the demux and a front-end previously
+ *	connected by a @connect_frontend call.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-EINVAL on bad parameter.
+ *
+ * @get_pes_pids: Get the PIDs for DMX_PES_AUDIO0, DMX_PES_VIDEO0,
+ *	DMX_PES_TELETEXT0, DMX_PES_SUBTITLE0 and DMX_PES_PCR0.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @pids function parameter contains an array with five u16 elements
+ *	where the PIDs will be stored.
+ *	It returns:

+/* Note that the cx25840 driver requires that the bridge driver calls the

+   Without this the audio standard detection will fail and you will
+   only get mono.
+
+   Since loading the firmware is often problematic when the driver is
+   compiled into the kernel I recommend postponing calling this function
+   until the first open of the video device. Another reason for
+   postponing it is that loading this firmware takes a long time (seconds)
+   due to the slow i2c bus speed. So it will speed up the boot process if
+   you can avoid loading the fw as long as the video device isn't used. */

+/* msp3400 routing
+   ===============
+
+   The msp3400 has a complicated routing scheme with many possible
+   combinations. The details are all in the datasheets but I will try
+   to give a short description here.
+
+   Inputs
+   ======
+
+   There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
+   to select which tuner input to use and which SCART input to use. The
+   selected tuner input, the selected SCART input and all I2S inputs go to
+   the DSP (the tuner input first goes through the demodulator).
+
+   The DSP handles things like volume, bass/treble, balance, and some chips
+   have support for surround sound. It has several outputs: MAIN, AUX, I2S
+   and SCART1/2. Each output can select which DSP input to use. So the MAIN
+   output can select the tuner input while at the same time the SCART1 output
+   uses the I2S input.
+
+   Outputs
+   =======
+
+   Most DSP outputs are also the outputs of the msp3400. However, the SCART
+   outputs of the msp3400 can select which input to use: either the SCART1 or
+   SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
+   bypassing the DSP.
+
+   Summary
+   =======
+
+   So to specify a complete routing scheme for the msp3400 you will have to
+   specify in the 'input' arg of the s_routing function:
+
+   1) which tuner input to use
+   2) which SCART input to use
+   3) which DSP input to use for each DSP output
+
+   And in the 'output' arg of the s_routing function you specify:
+
+   1) which SCART input to use for each SCART output
+
+   Depending on how the msp is wired to the other components you can
+   ignore or mute certain inputs or outputs.
+
+   Also, depending on the msp version only a subset of the inputs or
+   outputs may be present. At the end of this header some tables are
+   added containing a list of what is available for each msp version.
+ */
+
+/* Inputs to the DSP unit: two independent selections have to be made:
+   1) the tuner (SIF) input
+   2) the SCART input
+   Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
+   input, bits 4-7 are reserved.

+/* The msp has up to 5 DSP outputs, each output can independently select
+   a DSP input.
+
+   The DSP outputs are: loudspeaker output (aka MAIN), headphones output
+   (aka AUX), SCART1 DA output, SCART2 DA output and an I2S output.
+   There also is a quasi-peak detector output, but that is not used by
+   this driver and is set to the same input as the loudspeaker output.
+   Not all outputs are supported by all msp models. Setting the input
+   of an unsupported output will be ignored by the driver.
+
+   There are up to 16 DSP inputs to choose from, so each output is
+   assigned 4 bits.
+
+   Note: the 44x8G can mix two inputs and feed the result back to the
+   DSP. This is currently not implemented. Also not implemented is the
+   multi-channel capable I2S3 input of the 44x0G. If someone can demonstrate
+   a need for one of those features then additional support can be added. */

+/**
+ * struct tuner_params - Parameters to be used to setup the tuner. Those
+ *			 are used by drivers/media/tuners/tuner-types.c in
+ *			 order to specify the tuner properties. Most of
+ *			 the parameters are for tuners based on tda9887 IF-PLL
+ *			 multi-standard analog TV/Radio demodulator, with is
+ *			 very common on legacy analog tuners.
+ *
+ * @type:			Type of the tuner parameters, as defined at
+ *				enum param_type. If the tuner supports multiple
+ *				standards, an array should be used, with one
+ *				row per different standard.
+ * @cb_first_if_lower_freq:	Many Philips-based tuners have a comment in
+ *				their datasheet like
+ *				"For channel selection involving band
+ *				switching, and to ensure smooth tuning to the
+ *				desired channel without causing unnecessary
+ *				charge pump action, it is recommended to
+ *				consider the difference between wanted channel
+ *				frequency and the current channel frequency.
+ *				Unnecessary charge pump action will result
+ *				in very low tuning voltage which may drive the
+ *				oscillator to extreme conditions".
+ *				Set cb_first_if_lower_freq to 1, if this check
+ *				is required for this tuner. I tested this for
+ *				PAL by first setting the TV frequency to
+ *				203 MHz and then switching to 96.6 MHz FM
+ *				radio. The result was static unless the
+ *				control byte was sent first.
+ * @has_tda9887:		Set to 1 if this tuner uses a tda9887
+ * @port1_fm_high_sensitivity:	Many Philips tuners use tda9887 PORT1 to select
+ *				the FM radio sensitivity. If this setting is 1,
+ *				then set PORT1 to 1 to get proper FM reception.
+ * @port2_fm_high_sensitivity:	Some Philips tuners use tda9887 PORT2 to select
+ *				the FM radio sensitivity. If this setting is 1,
+ *				then set PORT2 to 1 to get proper FM reception.
+ * @fm_gain_normal:		Some Philips tuners use tda9887 cGainNormal to
+ *				select the FM radio sensitivity. If this
+ *				setting is 1, e register will use cGainNormal
+ *				instead of cGainLow.
+ * @intercarrier_mode:		Most tuners with a tda9887 use QSS mode.
+ *				Some (cheaper) tuners use Intercarrier mode.
+ *				If this setting is 1, then the tuner needs to
+ *				be set to intercarrier mode.
+ * @port1_active:		This setting sets the default value for PORT1.
+ *				0 means inactive, 1 means active. Note: the
+ *				actual bit value written to the tda9887 is
+ *				inverted. So a 0 here means a 1 in the B6 bit.
+ * @port2_active:		This setting sets the default value for PORT2.
+ *				0 means inactive, 1 means active. Note: the
+ *				actual bit value written to the tda9887 is
+ *				inverted. So a 0 here means a 1 in the B7 bit.
+ * @port1_invert_for_secam_lc:	Sometimes PORT1 is inverted when the SECAM-L'
+ *				standard is selected. Set this bit to 1 if this
+ *				is needed.
+ * @port2_invert_for_secam_lc:	Sometimes PORT2 is inverted when the SECAM-L'
+ *				standard is selected. Set this bit to 1 if this
+ *				is needed.
+ * @port1_set_for_fm_mono:	Some cards require PORT1 to be 1 for mono Radio
+ *				FM and 0 for stereo.
+ * @default_pll_gating_18:	Select 18% (or according to datasheet 0%)
+ *				L standard PLL gating, vs the driver default
+ *				of 36%.
+ * @radio_if:			IF to use in radio mode.  Tuners with a
+ *				separate radio IF filter seem to use 10.7,
+ *				while those without use 33.3 for PAL/SECAM
+ *				tuners and 41.3 for NTSC tuners.
+ *				0 = 10.7, 1 = 33.3, 2 = 41.3
+ * @default_top_low:		Default tda9887 TOP value in dB for the low
+ *				band. Default is 0. Range: -16:+15
+ * @default_top_mid:		Default tda9887 TOP value in dB for the mid
+ *				band. Default is 0. Range: -16:+15
+ * @default_top_high:		Default tda9887 TOP value in dB for the high
+ *				band. Default is 0. Range: -16:+15
+ * @default_top_secam_low:	Default tda9887 TOP value in dB for SECAM-L/L'
+ *				for the low band. Default is 0. Several tuners
+ *				require a different TOP value for the
+ *				SECAM-L/L' standards. Range: -16:+15
+ * @default_top_secam_mid:	Default tda9887 TOP value in dB for SECAM-L/L'
+ *				for the mid band. Default is 0. Several tuners
