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

  • RSX_RESET (syscon output, RSX input) <--------- Connected to RSX pad AW5 (RSX layout 41x41). Exists in Template:Syscon_pinout_LQFP_100_pins
  • RSX_VINTE1 / VD_VINT1 (syscon input, RSX output) <--------- Connected to RSX pad AL38 (RSX layout 41x41). Exists in Template:Syscon_pinout_LQFP_100_pins
  • RSX_CGRST (syscon output, RSX input) <--------- Connected to RSX pad AV6 (RSX layout 41x41) Nerfed in RSX with a 10k resistor to GND
  • SB_RESET (syscon output, south bridge input)
  • SB_CGRST (syscon output, south bridge input) <--- Nerfed too, like the RSX_CGRST ?
  • DISC_PHOT_LED (syscon output, bluray input) <--- disc insertion IR (emitter)
  • DISC_IN (syscon input, bluray output) <--- disc insertion phototransistor (receiver)
  • RSX_FBVDD_SEL (syscon output, RSX input) <----- existence doubtful
  • SW_HDD (syscon output, HDD power switch input) <------------ existence doubtful
  • POW_FAIL (syscon input, unknown source) <--- is the same than ACIN_DET pin 41 ?
