Bluray Drive, disc presence detector

There are 2 syscon pins dedicated to detect the disc insertion. One of pins powers a IR-LED (emitter), and the other pin is connected to a photo-transistor (receiver), both aligned with each other
When the disc interrupts the light beam a control signal is sent to syscon in the receiver pin. See BL1-001 and BL2-001

Missing lines

  • POW_FAIL (syscon input, unknown source) <--- is the same than ACIN_DET pin 41 ?
  • SB_RESET (syscon output, to south bridge)
  • SB_CGRST (syscon output, to south bridge)
  • RSX_RESET (syscon output, to RSX) <--------- Connected to RSX pad AW5 (RSX layout 41x41) ?
  • RSX_CGRST (syscon output, to RSX) <--------- Connected to RSX pad AV6 (RSX layout 41x41) ?
  • RSX_VINTE1 / VD_VINT1 (syscon input, from RSX) <--------- Connected to RSX pad AL38 (RSX layout 41x41). Exists in Template:Syscon_pinout_LQFP_100_pins
  • RSX_FBVDD_SEL (syscon output, to RSX) <----- existence doubtful
  • SW_HDD (syscon output, to HDD) <------------ existence doubtful
