/* 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! :)
