Hi folks,
I think i did it. The card is now working fine under linux with 16
inputs. In fact, i can tell you it's REALLY working: we just caught a
thief in our university thanks to the cameras. One guard sneaked into a
professor room at 3am to steal memory and hd and gave a nice shot to our
camera! he's being fired today...
I needed to create a muxsel_hook as the crosspoint switch has to be
reseted and pulsed to change the input channel. Also uncommented some
code related to gpiomask2.
The patch is for linux-2.4.13 (linus). More information within.
Thanks everybody for the help, if you need anything fell free to ask...
Regards,
Miguel Freitas

+/* RemoteVision MX (rv605) muxsel helper [Miguel Freitas]
+ *
+ * This is needed because rv605 don't use a normal multiplex, but a crosspoint
+ * switch instead (CD22M3494E). This IC can have multiple active connections
+ * between Xn (input) and Yn (output) pins. We need to clear any existing
+ * connection prior to establish a new one, pulsing the STROBE pin.
+ *
+ * The board hardwire Y0 (xpoint) to MUX1 and MUXOUT to Yin.
+ * GPIO pins are wired as:
+ * GPIO[0:3] - AX[0:3] (xpoint) - P1[0:3] (microcontroler)
+ * GPIO[4:6] - AY[0:2] (xpoint) - P1[4:6] (microcontroler)
+ * GPIO[7] - DATA (xpoint) - P1[7] (microcontroler)
+ * GPIO[8] - - P3[5] (microcontroler)
+ * GPIO[9] - RESET (xpoint) - P3[6] (microcontroler)
+ * GPIO[10] - STROBE (xpoint) - P3[7] (microcontroler)
+ * GPINTR - - P3[4] (microcontroler)
+ *
+ * The microcontroler is a 80C32 like. It should be possible to change xpoint
+ * configuration either directly (as we are doing) or using the microcontroler
+ * which is also wired to I2C interface. I have no further info on the
+ * microcontroler features, one would need to disassembly the firmware.
+ * note: the vendor refused to give any information on this product, all
+ * that stuff was found using a multimeter! :)
