/*      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.
