+	 * there could be some tuner I2C hacks done by firmware and this may
+	 * lead problems if firmware expects those bytes are used.
+	 *
+	 * TODO: Here is few hacks. AF9035 chip integrates AF9033 demodulator.
+	 * IT9135 chip integrates AF9033 demodulator and RF tuner. For dual
+	 * tuner devices, there is also external AF9033 demodulator connected
+	 * via external I2C bus. All AF9033 demod I2C traffic, both single and
+	 * dual tuner configuration, is covered by firmware - actual USB IO
+	 * looks just like a memory access.
+	 * In case of IT913x chip, there is own tuner driver. It is implemented
+	 * currently as a I2C driver, even tuner IP block is likely build
+	 * directly into the demodulator memory space and there is no own I2C
+	 * bus. I2C subsystem does not allow register multiple devices to same
+	 * bus, having same slave address. Due to that we reuse demod address,
+	 * shifted by one bit, on that case.
+	 *
+	 * For IT930x we use a different command and the sub header is
+	 * different as well:
+	 * 0: data len
+	 * 1: I2C bus (0x03 seems to be only value used)

+/* DVB USB compliant linux driver for Conexant USB reference design.
+ *
+ * The Conexant reference design I saw on their website was only for analogue
+ * capturing (using the cx25842). The box I took to write this driver (reverse
+ * engineered) is the one labeled Medion MD95700. In addition to the cx25842
+ * for analogue capturing it also has a cx22702 DVB-T demodulator on the main
+ * board. Besides it has a atiremote (X10) and a USB2.0 hub onboard.
+ *
+ * Maybe it is a little bit premature to call this driver cxusb, but I assume
+ * the USB protocol is identical or at least inherited from the reference
+ * design, so it can be reused for the "analogue-only" device (if it will
+ * appear at all).

+Guess at API of the I2C function:
+I2C operation is done one byte at a time with USB control messages.  The
+index the messages is sent to is made up of a set of flags that control
+the I2C bus state:
+0x80:  Send START condition.  After a START condition, one would normally
+       always send the 7-bit slave I2C address as the 7 MSB, followed by
+       the read/write bit as the LSB.
+0x40:  Send STOP condition.  This should be set on the last byte of an
+       I2C transaction.
+0x20:  Read a byte from the slave.  As opposed to writing a byte to the
+       slave.  The slave will normally not produce any data unless you
+       set the R/W bit to 1 when sending the slave's address after the
+       START condition.
+0x01:  Respond with ACK, as opposed to a NACK.  For a multi-byte read,
+       the master should send an ACK, that is pull SDA low during the 9th
+       clock cycle, after every byte but the last.  This flags only makes
+       sense when bit 0x20 is set, indicating a read.
+
+What any other bits might mean, or how to get the slave's ACK/NACK
+response to a write, is unknown.

+ * Register page 1:

+ * 0x78		Global control, bit 6 controls the LED (inverted)
+ * 0x80		Compression balance, 2 interesting settings:

+ *		0x50 Values >= this switch the camera to a lower compression,
+ *		     using the same table for both luminance and chrominance.
+ *		     This gives a sharper picture. Only usable when running
+ *		     at < 15 fps! Note currently the driver does not use this

+ * Address	Description
+ * 0x02		Clock divider 3-63, fps = 90 / val. Must be a multiple of 3 on
+ *		the 7302, so one of 3, 6, 9, ..., except when between 6 and 12?
+ * 0x03		Variable framerate ctrl reg2==3: 0 -> ~30 fps, 255 -> ~22fps
+ * 0x04		Another var framerate ctrl reg2==3, reg3==0: 0 -> ~30 fps,
+ *		63 -> ~27 fps, the 2 msb's must always be 1 !!
+ * 0x05		Another var framerate ctrl reg2==3, reg3==0, reg4==0xc0:
+ *		1 -> ~30 fps, 2 -> ~20 fps
+ * 0x0e		Exposure bits 0-7, 0-448, 0 = use full frame time
+ * 0x0f		Exposure bit 8, 0-448, 448 = no exposure at all
+ * 0x10		Gain 0-31
+ * 0x12		Another gain 0-31, unlike 0x10 this one seems to start with an
+ *		amplification value of 1 rather then 0 at its lowest setting
+ * 0x21		Bitfield: 0-1 unused, 2-3 vflip/hflip, 4-5 unknown, 6-7 unused
+ * 0x80		Another framerate control, best left at 1, moving it from 1 to
+ *		2 causes the framerate to become 3/4th of what it was, and
+ *		also seems to cause pixel averaging, resulting in an effective
+ *		resolution of 320x240 and thus a much blockier image
+ *
+ * The registers are accessed in the following functions:

+ *
+ * Address	Description
+ * 0x08		Unknown compressor related, must always be 8 except when not
+ *		in 640x480 resolution and page 4 reg 2 <= 3 then set it to 9 !
+ * 0x1b		Auto white balance related, bit 0 is AWB enable (inverted)
+ *		bits 345 seem to toggle per color gains on/off (inverted)
+ * 0x78		Global control, bit 6 controls the LED (inverted)
+ * 0x80		Compression balance, interesting settings:
+ *		0x01 Use this to allow the camera to switch to higher compr.
+ *		     on the fly. Needed to stay within bandwidth @ 640x480@30
+ *		0x1c From usb captures under Windows for 640x480
+ *		0x2a Values >= this switch the camera to a lower compression,
+ *		     using the same table for both luminance and chrominance.
+ *		     This gives a sharper picture. Usable only at 640x480@ <
+ *		     15 fps or 320x240 / 160x120. Note currently the driver
+ *		     does not use this as the quality gain is small and the
+ *		     generated JPG-s are only understood by v4l-utils >= 0.8.9
+ *		0x3f From usb captures under Windows for 320x240
+ *		0x69 From usb captures under Windows for 160x120
+ *
+ * Register page 4:
+ *
+ * Address	Description
+ * 0x02		Clock divider 2-63, fps =~ 60 / val. Must be a multiple of 3 on
+ *		the 7302, so one of 3, 6, 9, ..., except when between 6 and 12?
+ * 0x0f		Master gain 1-245, low value = high gain
+ * 0x10		Another gain 0-15, limited influence (1-2x gain I guess)
+ * 0x21		Bitfield: 0-1 unused, 2-3 vflip/hflip, 4-5 unknown, 6-7 unused
+ *		Note setting vflip disabled leads to a much lower image quality,
+ *		so we always vflip, and tell userspace to flip it back
+ * 0x27		Seems to toggle various gains on / off, Setting bit 7 seems to
+ *		completely disable the analog amplification block. Set to 0x68
+ *		for max gain, 0x14 for minimal gain.

+	  Support for external USB adapters designed by Technotrend and
+	  produced by Hauppauge, shipped under the brand name 'DEC2000-t'
+	  and 'DEC3000-s'.
+
+	  Even if these devices have a MPEG decoder built in, they transmit
+	  only compressed MPEG data over the USB bus, so you need
+	  an external software decoder to watch TV on your computer.
+
+	  This driver needs external firmware. Please use the commands
+	  "<kerneldir>/scripts/get_dvb_firmware dec2000t",
+	  "<kerneldir>/scripts/get_dvb_firmware dec2540t",
+	  "<kerneldir>/scripts/get_dvb_firmware dec3000s",
+	  download/extract them, and then copy them to /usr/lib/hotplug/firmware
+	  or /lib/firmware (depending on configuration of firmware hotplug).
+
+	  Say Y if you own such a device and want to use it.

+ * SOF = m * PTS + p
+ *
+ * Several methods to compute the slope (m) and intercept (p) can be used. As

+ * assume that the line that goes through the points at both ends of the window
+ * is a good approximation. Naming those points P1 and P2, we get

+ *     + (SOF1 * STC2 - SOF2 * STC1) / (STC2 - STC1)

+ * computed with
+ *
+ * TS = ((TS2 - TS1) * SOF + TS1 * SOF2 - TS2 * SOF1) / (SOF2 - SOF1)	     (2)
+ *
+ * SOF values are coded on 11 bits by USB. We extend their precision with 16
+ * decimal bits, leading to a 11.16 coding.
+ *
+ * TODO: To avoid surprises with device clock values, PTS/STC timestamps should
+ * be normalized using the nominal device clock frequency reported through the
+ * UVC descriptors.
+ *
+ * Both the PTS/STC and SOF counters roll over, after a fixed but device
+ * specific amount of time for PTS/STC and after 2048ms for SOF. As long as the
+ * sliding window size is smaller than the rollover period, differences computed
+ * on unsigned integers will produce the correct result. However, the p term in
+ * the linear relations will be miscomputed.
+ *
+ * To fix the issue, we subtract a constant from the PTS and STC values to bring
+ * PTS to half the 32 bit STC range. The sliding window STC values then fit into
+ * the 32 bit range without any rollover.
+ *
+ * Similarly, we add 2048 to the device SOF values to make sure that the SOF
+ * computed by (1) will never be smaller than 0. This offset is then compensated
+ * by adding 2048 to the SOF values used in (2). However, this doesn't prevent
+ * rollovers between (1) and (2): the SOF value computed by (1) can be slightly
+ * lower than 4096, and the host SOF counters can have rolled over to 2048. This
+ * case is handled by subtracting 2048 from the SOF value if it exceeds the host
+ * SOF value at the end of the sliding window.
+ *
+ * Finally we subtract a constant from the host timestamps to bring the first
