/* 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 connectd 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 receiption 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 cant 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 freqency, 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 seting DD1_INIT trigger mode 7 in 3rd nibble.
