Support for SAA7146 and AV7110 based DVB cards as produced
by Fujitsu-Siemens, Technotrend, Hauppauge and others.
This driver only supports the fullfeatured cards with
onboard MPEG2 decoder.
This driver needs an external firmware. Please use the script
"<kerneldir>/Documentation/dvb/get_dvb_firmware av7110" to
download/extract it, and then copy it to /usr/lib/hotplug/firmware
or /lib/firmware (depending on configuration of firmware hotplug).
Alternatively, you can download the file and use the kernel's
EXTRA_FIRMWARE configuration option to build it into your
kernel image by adding the filename to the EXTRA_FIRMWARE
configuration option string.
Say Y if you own such a card and want to use it.

help
The AV7110 firmware provides some code to generate an OnScreenDisplay
on the video output. This is kind of nonstandard and not guaranteed to
be maintained.
Anyway, some popular DVB software like VDR uses this OSD to render
its menus, so say Y if you want to use this software.
All other people say N.

Support for Budget Patch (full TS) modification on
SAA7146+AV7110 based cards (DVB-S cards). This
driver doesn't use onboard MPEG2 decoder. The
card is driven in Budget-only mode. Card is
required to have loaded firmware to tune properly.
Firmware can be loaded by insertion and removal of
standard AV7110 driver prior to loading this
driver.
Say Y if you own such a card and want to use it.
To compile this driver as a module, choose M here: the
module will be called budget-patch.

/* OLD (Original design by Roberto Deza):
** This code will setup the SAA7146_RPS1 to generate a square
** wave on GPIO3, changing when a field (TS_HEIGHT/2 "lines" of
** TS_WIDTH packets) has been acquired on SAA7146_D1B video port;
** then, this GPIO3 output which is connected to the D1B_VSYNC
** input, will trigger the acquisition of the alternate field
** and so on.
** Currently, the TT_budget / WinTV_Nova cards have two ICs
** (74HCT4040, LVC74) for the generation of this VSYNC signal,
** which seems that can be done perfectly without this :-)).
*/
/* New design (By Emard)
** this rps1 code will copy internal HS event to GPIO3 pin.
** GPIO3 is in budget-patch hardware connected to port B VSYNC
** HS is an internal event of 7146, accessible with RPS
** and temporarily raised high every n lines
** (n in defined in the RPS_THRESH1 counter threshold)
** I think HS is raised high on the beginning of the n-th line
** and remains high until this n-th line that triggered
** it is completely received. When the reception of n-th line
** ends, HS is lowered.
** To transmit data over DMA, 7146 needs changing state at
** port B VSYNC pin. Any changing of port B VSYNC will
** cause some DMA data transfer, with more or less packets loss.
** It depends on the phase and frequency of VSYNC and
** the way of 7146 is instructed to trigger on port B (defined
** in DD1_INIT register, 3rd nibble from the right valid
** numbers are 0-7, see datasheet)
**
** The correct triggering can minimize packet loss,
** dvbtraffic should give this stable bandwidths:
** 22k transponder = 33814 kbit/s
** 27.5k transponder = 38045 kbit/s
** by experiment it is found that the best results
** (stable bandwidths and almost no packet loss)
** are obtained using DD1_INIT triggering number 2
** (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
** and a VSYNC phase that occurs in the middle of DMA transfer
** (about byte 188*512=96256 in the DMA window).
**
** Phase of HS is still not clear to me how to control,
** It just happens to be so. It can be seen if one enables
** RPS_IRQ and print Event Counter 1 in vpeirq(). Every
** time RPS_INTERRUPT is called, the Event Counter 1 will
** increment. That's how the 7146 is programmed to do event
** counting in this budget-patch.c
** I *think* HPS setting has something to do with the phase
** of HS but I can't be 100% sure in that.
** hardware debug note: a working budget card (including budget patch)
** with vpeirq() interrupt setup in mode "0x90" (every 64K) will
** generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
** and that means 3*25=75 Hz of interrupt frequency, as seen by
** watch cat /proc/interrupts
**
** If this frequency is 3x lower (and data received in the DMA
** buffer don't start with 0x47, but in the middle of packets,
** whose lengths appear to be like 188 292 188 104 etc.
** this means VSYNC line is not connected in the hardware.
** (check soldering pcb and pins)
** The same behaviour of missing VSYNC can be duplicated on budget
** cards, by setting DD1_INIT trigger mode 7 in 3rd nibble.

/*
Retrieve encoded MAC address from 24C16 serial 2-wire EEPROM,
decode it and store it in the associated adapter struct for
use by dvb_net.c
This card appear to have the 24C16 write protect held to ground,
thus permitting normal read/write operation. Theoretically it
would be possible to write routines to burn a different (encoded)
MAC address into the EEPROM.
