[PATCH] dvb: dvb-ttpci: fix SMP race, budget: fixe init race, misc fixes

- [DVB] dvb-ttpci: re-added support for Fujitsu-Siemens DVB-S rev 1.6 0x13c2:0x0006
- [DVB] dvb-ttpci: finally clean up debi irq/tasklet handling to make it work on SMP
- [DVB] dvb-ttpci: misc. changes to av7110_send_fw_cmd() error handling done along the way
- [DVB] dvb-ttpci: budgetpatch integrated into dvb-ttpci: enables full ts option running
        in parallel with all previous functions of dvb-ttpci
- [DVB] dvb-ttpci: fix Oops provoked by insmod/rmmod test loop, patch by Emard
- [DVB] budget: Fixed start_ts_capture(): saa7146 will not issue a VPE interrupt
        if VPE bit is set in PSR and VPE interrupts are enabled afterwards.
- [DVB] budget: enable satelco support. code was commented out, but actually it works, patch by Emard
- [DVB] budget: Budget patch improved driver, fixed slight packet loss by using different trigger mode

+/* Budgetpatch note:
+ * Original hardware design by Roberto Deza:
+ * There is a DVB_Wiki at
+ * http://212.227.36.83/linuxtv/wiki/index.php/Main_Page
+ * where is described this 'DVB TT Budget Patch', on Card Modding:
+ * http://212.227.36.83/linuxtv/wiki/index.php/DVB_TT_Budget_Patch
+ * On the short description there is also a link to a external file,
+ * with more details:
+ * http://perso.wanadoo.es/jesussolano/Ttf_tsc1.zip
+ *
+ * New software triggering design by Emard that works on
+ * original Roberto Deza's hardware:
+ *
+ * rps1 code for budgetpatch 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.

+/*      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

+**      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.

+**      (check soldering pcb and pins)
